Question

Dot plot help*

Calculate the measure of the center for the data in the dot plot, rounding your answers to the nearest tenths place. Show how you determined your answer.

Answer 1

I found the average by adding 0(1)+4(3)+5(8)+6(3)+7(1)+8(5)+9(2)+10(3)=165. After this, I counted the number of C’s shown, which is 26. I divided 165 by 26 and got 6.346. To the nearest ten, the answer is 6.3

Answer 2

The mode if 5, because 5 occurs 8 times, which is more than any other numbers occurring more than once. The median is 6, and this is because when you line up the numbers in order and cross them off to find the middle number, it is 6. I rounded to the mean to about 6.4. I got this by adding all of the numbers up, or by doing 12 + 40 +18 +7, etc, and got the total of 165. Because there is a total of 26 data points, I divided those numbers and got 6.3461, which ends up rounding to 6.4.
