If you are using statistics to compute a sample mean you should divide the sum of all observations in your sample by A. 1. B. The sample size minus 1 (n - 1). C. The sample size (n). D. The sample size minus 2 (n - 2). E. None of the above.
Homework Answers
Solution:
Given that,
Option C is correct.
Answer: The sample size (n)
because,
The formula for sample mean is,
x bar = sum of observation / n

You should have found ∑X = 160, N = 16, so M = 10. Make sure you
understand how each of these values was computed. 20. Although you
have been able to compute the mean for a long time now, you
probably don’t know “what the mean does” or how it “defines”
center. The mean defines center by balancing deviation scores. In
