Take any concept that we have covered so far in the class and explain it. Basically, talk us through what it means or how we calculate it. Hopefully, your explanation will help you make more sense of the material and assist your classmates in reviewing/understanding everything that we have done! Be detailed in your discussion and be sure to read others' posts so that you can have a nice review of the material.
As mentioned on Blackboard, please go to this website, read the graphs, and discuss one statistic and one trend here (thus, post again). Let's practice!

ReplyDeleteI am going to discuss percent increase. We all know that a percent is a portion out of 100. A percent increase is when we ask if number X increased to number Y, by how much percent did X increase. To figure this out we use the formula:
(New amount-old amount)/old amount
For example, let's say I bought a necklace for $10 and I want to sell it to someone else for $15 how much would the percent increase be? We take (15-10)/10=.5 or 50%. The percent increase was 50%.
Good start to the blog!
ReplyDeleteI am going to teach the mean. For my example im going to use the following numbers:
ReplyDelete20,5,10,5 and 8
The mean is the average so to find it by using the above numbers add them (20+5+10+5+8=48) then divide the sum by the number of digits used. There are 5 numbers so divide the sum by 5.(48/5 = 9.6) So 9.6 is the average of the above numbers. Easy right?
I am going to teach median. The median is the midpoint of a set of numbers. The median is also an average. However the difference between the mean and median is that mean is sensitive to the extremes and the median is not. In order to compute the median, the data has to be put in order from either highest to lowest or lowest to highest.
ReplyDeleteEX. 2, 10, 1, 0, 12, 5, 8
1. put number in order
0, 1, 2, 5, 8, 10, 12
2. the midpoint is the middle number
median=5
EX. 5, 9, 7, 8
1. put numbers in order
5, 7, 8, 9
2.the midpoint is the middle number and when you have an even number of data you take the two middle numbers and add the together and divide by 2.
7+8=15 15/2=7.5
3.the median is 7.5
I would like to talk about the mode. The mode is basically the number that shows up the most.
ReplyDeleteFor example if I had the numbers 2 4 6 4 8 5 4... the mode would be the number four because thats the number that shows up the most.
Converting Fractions to a percent 30/50 (divide the numerator by the denominator)=0.6 then multiply by 100 =60 remember to move the decimal
ReplyDeleteI'm going to review graphs. A graph is a visual display of collected & organized data. The type of graph used depends on the type of data collected. There are 3 types of graphs (1) Line graphs used to show changes over time. (2) Bar graphs (vertical or horizontal) used to compare quantities and (3) Cirle graphs or Pie charts, used to divide into parts.
ReplyDeleteI am going to talk about percent increase, this is when we want to find out how much more we have of something. For example lets say a person worked 10 hours and now they work 13 and you want to find how much of a raise they received for working more hours. You will take the new amount of hours which is 13 and subtract the old amount of hours which is 10 and you should get 3. Now take 3 and divide this by 10 which is the old amount of hours you used to work. Your answer should come out to .3 now take this number and multiple it by 100 and you should get 30% and this is the increase in your pay.
ReplyDeleteI am going to talk about how to calculate percent.
ReplyDelete1. 13 students in Mr. Best class made an A on their exam. 5 students made a B. 3 students made and C. 2 students made a D. 1 student made and F. Now what percent of students out of the class made an A.
1. add all the students in the class that took the exam = 24
2. Now we need to make a fraction = number of students who made an A goes on the top (13)
The total number of students in the class goes on the bottom (24)
3. Now we just simply divide 13/24=.54166666
4. Know you notice that we have a decimal instead of a percent. All you have to do is take the decimal .54166666 and multiply it by 100 to get a percent.
5. Take .54166666 * 100 = 54.2 percent
6. Now your answer is that 54.2 percent of students in Mr. Best class made and A
I will explaining how to figure out the tip of a bill. People have to realize that waitors/waitresses need that tip to pay their bills. ok, lets say that your bill was 85.45 and you are naturally supposed to leave 15% tip. You would take (85.45 * .15) = $12.82 or the amt. of bill and multiply by 15%(.15). Remember that waitresses dont make minimum wage so you need to tip them...THANKS
ReplyDeleteIm going to talk about mean, median, and mode...
ReplyDeleteWhen trying to find these 3 things we have to know what they mean.
mean= the average
median= the number in the middle
mode=is the number that occurs the most
How do you find them:
-to find the mean- you take all the numbers in your list add them up and divide by how many numbers you there are.
-to find the median- you have to put your numbers in order and find the number in the middle.
-to find the mode you just look in you list for the number that occurs the most
-Alicia Hill
Since everything I think I wanted to talk about is above me, I will discuss using formulas on excel.
ReplyDelete1st. To find the mean on excel you would list the numbers vertically in the first column (A column) Lets say you have 10 numbers so you have numbers in the a1 through a 10 column. in Column A11 you would type the equal sign, the word average then in parenthesis write the cells that you are trying to calculate. In this case it would be a1 through a10. Instead of - you would use the colon. Check below for the example.
A B C
1 10
2 8
3 18
4 20
5 7
6 7
7 9
8 10
9 16
10 6
11 =Average(a1:a10)
Then the formula will dissapear and the average will then be in box a11 like so
A B C
11 11.1
Mode formula is =Mode(a1:a10)
Median Formula =Median(a1:a10)
Multiplication =Product(a1:a2)

.....so pretty much everything has been said but i guess i still can give an example!
ReplyDelete....Statistics is all about Numbers that tells different types of stories and they help us to uderstand what's going on!
I will be doing an example using percentage.
ReplyDeleteWhat percent of 20 is 30?
The original number (20) and the comparative number (30). The unknown in this problem is the rate or percentage. Since the statement is "(thirty) is (some percentage) of (twenty)", then the variable stands for the percentage, and the equation is:
30 = (x)(20)
30 ÷ 20 = x = 1.5
Since x stands for a percentage, I need to remember to convert this decimal back into a percentage:
1.5 = 150%
Thirty is 150% of 20.
My best example is in my family their are four children 3 girls and 1 boy. My percentage is 75% female and 25% male when it comes to voting on such things like what color to paint the bathroom that we all share.
Today i will be discussing the mode. The mode is the number that show up the most frequently out of a group of numbers. As for example if you have the following numbers 2,6,4,8,6,5,6 then the mode would come out to be 6 because that is the number that shows up the most frequently.Hope you learn and get a better understanding of the mode from my discussin and example.
ReplyDeleteGood work so far! I hope that everyone has been reading these posts, as it's been a great review of the course so far. If you feel as if "everything" has already been stated, you can always offer more examples.... - Dr. G
ReplyDeleteI will be explaining mean, median, and mode. The mean is basically the average. You add all the numbers up and divide all by the number of cases. The median is the middle number of a set of numbers from least to greatest. The mode is the number that occure the most. Below are some examples of each:
ReplyDeleteMean: 0,2,3,1,10,2
0+2+3+1+10+2= 3<---- answer
Median: 5,4,7,2,3
2,3,4,5,7: 4<---- answer
Mode: 0,7,5,0,6,4,0,7,0
0<---- answer
Here is how to find the mean of a group of numbers.
ReplyDeleteStep 1)Pick a set of numbers. Let’s use 89, 87, 57, 94 and 73.
Step 2)Find the mean of your group of numbers. To do this, simply find the average (the sum of the terms divided by the number of terms). So 89 + 87 + 57 + 94 + 73 = 400. And 400 ÷ 5 = 80. The mean is 80

ReplyDeleteWell several people have talked about what I am going to discuss but I will say it again because this piece of information has SIGNIFICANT importance to me. How to figure out by how much percent something in numbers is increased. So say for example you are sharing an amount of money- say $500.00 and your share is $40.00, you think you should get more than $40.00. So the other person offers you a 20% increase in your share. 20% sound like a substantial percent so you may be quick to agree, but here is where it gets tricky. So an increase of 20% to $40.00 looks like this 40x.20=8. So to find out how much your increased share is you add the 8, which represents the AMOUNT of increase to your share, to your original share amount of 40 and you get $48.00. But even though your share increased by 20%, the percent of your portion of the entire amount has not gone up very much at all. To find out what percent of the whole $500.00 was when you were getting $40.00 you divide 40 by 500 which gives you .08 then multiply that by 100 (or move the dicimal over to the left two spaces) and you have 8%. That is what your $40.00 share was. To find out what the new 20% increased share amounts to in relation to the whole pot of $500.00 you do the same thing with the new amount - 48 divided by 500 and you get .096 Again multiply the .096 by 100 (or move the decimal over to the left two spaces) and you get 9.6%. So to find out by how much percent did your portion icrease of the whole amount you subtract the 8% from the 9.6% and you find that it is only a 1.6% increase of the whole pot. That is why you have to be very careful about how percent increases are applied.
Men and women had an increase in actual earnings between 1960 and 2001.
ReplyDeleteMen made $37k in actual earnings in 1973, while women made $22k during the same time.
Rachel Weathers....
ReplyDeleteI have selected the last graph titled, A Continuing Gap in U.S. Earning Trends?
One statistic is that full time, year round working women 15 years and older made only around $16K in 1960 compared to full time, year round working men 15 years and older who made $27K in 1960. One trend on this graph is that as the years go by men and women are making more money but there is still a large gap in the wages earned between men and women.
When taking a look at percent increase, you always subtract the lowest from the highest number,... then divide it by the lowest number. So if you made 35000 and you recieved a raise and now you make 37500. That means you would do 37500-35000=2500...then 2500/35000=.071 So you had a 7% increase.
ReplyDeleteEarnings in Relationship to Simarily Educated Men Graph. Says 73% of women with only a highschool education make more than men. One trend is that 75% women with associate degree along with 75% of women with bachelors degree have a higher earning than of men with.

ReplyDeleteYou and your friends are out having drinks and the waiter brings your bill. The bill is $71.29. AS a customer you have opptions, you and your friends could leave the waiter a 5%,10%,15% or a 25% tip. The friends choose to leave a 15% tip. To find out how much they are leaving, they will Multiply the total price by the 15%. Example: "71.29*.15=10.69". The waiter tip is $10.69.

ReplyDeleteWell I haven't worked with mean, mode, and median since middle school and I forgot how to solve the median. Heres the solution to that
For example,in this group of numbers 1,3,5 the median is 3. But in a group with an even about of numbers like this group 9,6,1,4 the median of the list (1,4,6,9)(put the numbers in order frm less to greatest) take the two middle numbers which is 4 and 6, and find the mean
i.e. ---> (4 + 6)/2 = 5

ReplyDeleteA Continuing Gap in U.S. Earning Trends?
One statistic fact that this graph show is that in 1969 women earned 20k while the men earned between 33k and 34k. One trend that I noticed on this graph is that as time goes on men and women earnings increase. However a large gap would remain between men and women wages.
Hey i am going to teach how to do the mean, mode, and median. The mean is the average so what you would do is add up all the numbers then divide it by the amount of all the digits add up so for example you can have shots basketball shots 10,20,4,8,6,7,2,2 an then you would add all those numbers up so the answer would be 59 now you would divide that by 8 because there are seven numbers an it gives you 7.35. Now when it comes down to the mode all you do is number thats shows up the most in this case it would be 2. Finally median all you do is arrange the numbers in order from smallest to biggest like this 2,2,4,6,7,8,10,20 and then see what number is in the middle which is 6 and 7 now you would add 6 and 7 up and divide by 2 which is 13 and when dived by to gives us 6.5 That is how you can find the mean, mode and, median
ReplyDeleteThe concept I would like to discuss would be the disadvantage of using the mean as oppossed to the median. Unlike the median, the mean is sensitive to the extremes. So say u have a group of numbers like 3,5,5,6,7,8,80. Using the mean would push the average of these numbers to 16.3 this could be misleading because there is only one number that is even above 16 and that number is 80. If the median were used in this situation u would get a better idea because the high number is no so influential while using the median.

ReplyDeleteA specific statistic about the graph is that in 1991, 97% of a similar mens annual earnings were shared with full time working black women.
A trend would be that the minority of ethnicity groups are higher then the majority ethnicity group.
In the Gender wage gap graph, a statistic would be in 2000 white women annual earnings were 70% similar to men. A trend would be as the years increase, white women annual earnings decrease
ReplyDeleteIn the graph entitled "Earnings in Relation to Similary Educated Men's Earrings." 60% of women 25 years or Older with a Professional degree still make way less then men. A trend that I have observed is women who receive higher education still make less money then men do.
ReplyDeleteAccording to the chart entitled Earnings Related to Similarly Educated Men's Earnings, one statistic is 75% of women who are 25 years or older with a bachelor's degree make less than similarly educated men.
ReplyDeleteOverall the trend is that the higher the education a women 25 years or older has the overall earning rate stays about the same unless the degree is a professional degree where the earnings decrease.
Earnings in Relation to Similarly Educated Men's Earnings
ReplyDeleteStatistic: Women who earned an associate degree earned 75% of what men earned with a similar education
Trend: The more educated a woman is the less likely she is to earn what men earn
The graph that i choose to do was "Earnings In Relation To Similarly Educated Men's Earnings", a stastic that i observed was that 75% of women 25 years or older with a doctorate degree makes less then similarly educated men. Trend:Women who get a higher education still makes less then men.
ReplyDeleteCalculating the mean is one of the simplist processes in statistics. Take this set of numbers for example; {10 9 3 8 7 2 1 15 4 6} take the sum of these numbers(65) and divide by the quantity of the numbers(10). Your answer should be 6.5.
ReplyDeleteU.S. Gender Wage Gap Within Ethnicity Annual as a Percentage of Similar Men's:
Statistic shows that Asian/Pacific islander women earned 87% of what Asian/pacific islander men made in 1997. A trend would be between 1988 and 2001 it seems as tho hispanic and black women earned about the same.
I am going to show how to use mean. My example im going to use the following numbers:
ReplyDelete30,7,12,5 and 3
The mean is the average, in order to figure it out u will need to add all the numbers up(30+7+12+5+3+9=66) then divide the sum by 6. the average is 11 because 6 divided by 66 is 11
Earnings in Relation to Similarly Educated Men's Earnings
ReplyDeleteStatistic: Women who earned an some college and earned 72% of what men earned with a similar education
Trend: The higher the degree a women earns, she is less likely she is to earn what men earn
In year 2000, hispanic woman made 85% of what hispanic men made.
ReplyDeletein 1991, Black woman made 92% of what black men made.
In 1988 it seems that hispanic and black woman earned the same while white woman earned the least.
Hispanic woman stayed making between 85 and 92% from 1988-2001
LaQuita
In the year of 2000 black women maden 82% of what an a white women made. with all the groups from 1988 to 2000 the ratings increased and the decreased back to increasing back up to hispanic women.
ReplyDeleteRosa Saavedra
ReplyDeleteFirst let me say that I may be completly confused about these graphs but from what I can figure out it seems that there is a trend among asian and pacific islander women 15 years and older working full time -their year round median annual earnings seems to be decreasing. For the year 1988 this groups earnings as a percentage of similar mens earnings was about 90% and by year 2000 that percentage was about 70%. Of all the groups of women represented on this chart this group seems to be experiencing wider wage gap. i think this chart has the potential to make it appear that white women are the group with the largest disparity of wage difference but you really have to take into consideration that the comparison of white women is being made to white men - who are the group with the highest income. So it might be that for example in year 2000 white men made 100,000 and white women made 70% of that or 70,000. While for Latinos the numbers may be 50,000 and latina women made about 85% of that or 42,500. so even though the picture looks like white women are making less, that may not be the case.
In the graph,"Earnings in Relation to Similary Educated Men's Earrings", I notice about 60% of women 25 years or Older with a Professional degree make less than men. A trend would be women who receive higher education still make less money than men do. (Which is unfair)
ReplyDeleteI am going to discuss mean.
ReplyDeletemean=average
basically the concept is pretty easy. for example.....
10,21,45,76,93,85,77
lets say that these are all scores received on quizes. We want to figure out what would be the average score that the student would receive in the class. so we would add each score together and devide the total by the number of quizes that was taken.
10+21+45+76+93+85+77=407
407/7=58.14
we would then round to the nearest 10th which would make the student's average for the class 58.1....not so good
I will explain median. Say the data is
ReplyDelete12,45,67,43
In order to get the median ariange the numbers in order from least to greatest which is:
12,43,45,67
Next since there are two numbers in the midde add them and divide them by 2 and the answer is 44
