Question

FAN AND MEDAL! Ike made the following long jumps - 12 ft, 14.5 ft, 16 ft, and 13.5 ft. What is the mean absolute deviation of his four jumps...

Answer 1

first find the mean of those 4 data values

Answer 2

14

Answer 3

excellent, the mean is 14

our next step is to look at each data point and calculate its distance from 14

so basically, we calculate:

| 12 - 14 | = __
| 14. 5 - 14 | = __
|16 - 14 | = __
|13.5 - 14| = __

Answer 4

| | means absolute value

Answer 5

-2, .5, 2, -.5

Answer 6

almost, absolute value means we take off any negative signs

so our values are 2, 0.5, 2, 0.5

now take the mean of those 4 numbers and we'll have our answer!

Answer 7

5!
