Answer to relevant QuestionsWhy is it necessary to have more than one method for measuring central tendency? A population of N = 15 scores has a mean of m = 8. One score in the population is changed from X = 20 to X = 5. What is the value for the new population mean? One sample has a mean of M = 8 and a second sample has a mean of M = 16. The two samples are combined into a single set of scores. a. What is the mean for the combined set if both of the original samples have n = 4 ...For the following population of N = 6 scores: 11 0 2 9 9 5 a. Calculate the range and the standard deviation. (Use either definition for the range.) b. Add 2 points to each score and compute the range and standard deviation ...Calculate SS, variance, and standard deviation for the following population of N = 6 scores: 1, 6, 10, 9, 4, 6.
