6. Find   the mean, median and mode for the set of scores in the following frequency   distribution table:       X F    10 2    9 3    8 5    7 6    6 3    5 1   

14. A   sample of N=6 scores has a mean of M=12 if the one person with a score of X=8   is removed from the sample what will be the new value for the new mean?

16. A   population of N=8 scores has a mean of u=20 if one score is changed from X=14   to X=20 what will be the value for the new mean?   

22. One   sample of n=20  scores has a mean of m=50 a second sample of n=5   scores has a mean of M=10. If the two samples are combined what is the mean   for the combined sample? 

24   Identify the circumstances in which the median rather than the mean is the   preferred measure of central tendency.
