Question

Math help! Mean Deviation and Percentiles!

Answer 1

6-3 (6 feet, 3 inches)
6-5
6-8
6-6
6-8
6-8
6-10
6-3
7-1
6-7
6-9
6-10
6-5
6-6
Find the minimum (smallest), maximum (largest), median, 25th percentile, and 75th percentile for the data set
Calculate the mean, to the nearest inch, for the set of data. Enter the value in the essay box below. You might wish to convert the heights to inches first
Calculate the mean deviation, to the nearest inch, for the set of data.
. Using the mean deviation, between what two heights would expect to find the height of a Phoenix Suns player?
I really need someone to help me solve this

I have this so far smallest-6-3
largest-7-1
median- 6-7 and 6-8 (6-7.5)

Answer 2

4. Using the mean deviation, between what two heights would expect to find the height of a Phoenix Suns player?

5. On a sheet of paper, construct a box-and-whisker plot for the heights of the players on the Phoenix Suns basketball team roster for the 2007-2008 season.

Answer 3

i need help with number 4 and 5!

Answer 4

ahh stats ...ok give me a few minutes to read everything

Answer 5

Ok!

Answer 6

ok box whisker plot is easy



and what do they mean by "mean derivation"
\[\frac{\sum_{?}^{?}|x-mean|}{n}\]
?

Answer 7

Okay one sec let me look again

Answer 8

The mean deviation (also called average deviation) gives the average distance of the data points from the mean.



Study the example shown on the right and follow the steps below to calculate the mean deviation:

Find the mean. (810 ÷ 10 = 81)
Find the difference between the first data point and the mean.

This is called the deviation.
Take the absolute value of the deviation.
Repeat this process for each data point.
Find the mean of the deviation values. (86 ÷ 10 = 8.6)
The mean deviation for the data set shown is 8.6.

Answer 9

Okay I got the box wisker plot down now the problem is understanding the mean deviation and putting the numbers in the whisker plot

Answer 10

well looks like you already have the numbers for whisker plot right?

for mean deviation just plug in each height and subtract from mean, take absolute value
add up all of these "deviations" and divide by the total number of players

Answer 11

absolute value?

Answer 12

same as making number positive
|-6| = 6
|6| = 6

Answer 13

Thanks man you helped a lot,I subtracted the heights from the mean and plugged them in the plot thanks alot been stuck on this for days
