Explanation Given: Assume that in your Abnormal Psychology class you have earned test scores of 74, 81, 56, and 70, and only one test remains. Formula used: Mean: If a data set contains n data values, the mean x ¯ of the data set is x ¯ = ∑ x n Calculation: Consider the given data set of scores of 4 test, 74, 81, 56, and 70 Let score in 5 th test be x To determine b) To calculate: The scores obtained in final test when a mean score of 80 is needed to earn a B.
