Question

Determine the mean for the following raw scores of a pretest used in a marketing research study: 82, 83, 25, 29, 31, 82, 30, 90, 56, 76, 40, and 45. *

Answer 1

55.75

Step-by-step explanation:

Mean is the average score in the marketing data. It is obtained by first finding the total of all the data. The total is then divided by the number of entries.

The total for this data is 82 +83 + 25 + 29 + 31 + 82+ 30 +90+ 56, 76 +40+ 45= 669

The mean will be 669 divided by 12

=669/12

=55.75
