Question

A team of researchers measured the length of 5 different rainbow trout pulled from different locations in a lake. length, in.: {18, 22, 15, 28, 17} what is the estimated mean absolute deviation of the lengths of rainbow trout in the lake? 1.3 in. 4 in. 20 in. 61 in.

Answer 1

Answer:

4 in

Step-by-step explanation:

18 + 22 + 15 + 28 + 17 = 100

100 / 5 = 20

So, the mean for the data set: 18, 22, 15, 28, 17 is 20.

18 - 20 = |2|

22 - 20 = |2|

15 - 20 = |5|

28 - 20 = |8|

17 - 20 = |3|

2 + 2 + 5 + 8 + 3 = 20

20 / 5 = 4

So, 4 in is the mean absolute deviation (MAD).

I also took the test.
