Textbook Problem

A sample of n = 7 scores has a mean of M = 16. One score in the sample is changed from X = 6 to X = 20. What is the value for the new sample mean?

To determine

To Find: The value of new sample mean when a score is changed from 6 to 20.

Explanation

Given info:

A sample of 7 scores has mean 16.

Calculation:

Let the 6 scores = x1x2x3x4x5x6 and 7th score x7=6

The formula for sample mean is:

M=Xn

Substitute the values X=x1+x2+x3+x4+x5+x6+6,n=7,M=16 in the above formula

16=x1+x2+x3+x4+x5+x6+67112=x1+x2+x3+x4+x5+x6+6106=x1+x2+
