QUESTION:
The first four deviations from the mean in a sample of n = 5 reaction times were .3, .9, 1.0, and 1.3. What is the fifth deviation from the mean? Give a sample for which these are the five deviations from the mean.
ANSWER:Answer :
Step 1 :
Given the first four deviations from the mean in a sample of n= 5 reaction times were 0.3, 0.9, 1.0, and 1.3.
We know that reaction times were 0.3, 0.9, 1.0, and 1.3.
0.3+0.9+1.0+1.3 =0
Therefore the total of four deviations is 3.5
The sum of the deviations of items taken from Actual Mean is always be equal to 0 irrespective of the number of items.
