The mean of a sample distribution is 5.0 If 4 were added to each score in the distribution the mean of the distribution would be?
The answer is 9. Let's first use and example, then view it conceptually. If we have scores of 3, 4, 5, 6, and 7, the mean will be five. (3 + 4 + 5 + 6 + 7)/5 = 25/5 or 5 If we add 4 to each of those scores we will then have: (7 + 8 + 9 + 10 + 11)/5 = 45/5 = 9 To see that this will work for all sets of scores, think of the formula for the mean: (a1 + a2 + a3 ... + an)/n = original mean Where a represents a single score in the distribution and n = number of scores in the sample. If we were to add 4 to each of the scores, then: [(a1+4) + (a2+4) + (a3+4) ... + (an+4)]/n [(a1 + a2 + a3 ... + an)+4n]/n [(a1 + a2 + a3 ... + an)/n] + 4 original mean + 4
