Question

Homework #2 (10 Points Total)- Show Work! A sample of n -9 scores has a sum of 108. What is the only measure of central tendency you can calculate with this information? Identify it and compute it. 1. Compute the mean, median, and mode for the following three sets of scores: a. 2. 3,7, 5, 4, 5, 6, 7,8, 6, 5 b. 34, 54, 17, 26, 34, 25, 14, 24, 25, 23 c. 154, 167, 132, 145, 154, 145, 113, 156, 154, 123 3. One sample of n =IO has a mean of 8 and a second sample of"-5scores has a mean of 2. If the two samples are combined, what is the mean for the combined sample? Explain your reasoning. (Hint: Use your notes on weighted means.") 4. Under what conditions would you use the median rather than the mean as a measure of central tendency? Why? Provide two specific examples of two situations in which the median might be more useful than the mean as a measure of central tendency 5. Under what conditions would you use the mode rather than the mean as a measure of central tendency? Why? Provide two specific examples of two situations in which the mode might be more useful than the mean as a measure of central tendency.

Explanation / Answer

1.

Formula of mean is

X/n = 109/9= 12

so average or arithmetic mean is the central tendacy which we identified here.

Please post remaining questions saperately.

Hope above answer will helps you. Thanks and God Bless You :-)
