Directions: Use the table below to determine the standard deviation of the given test scores. Show all calculations and values in the chart. Round the mean, standard deviation, and variance to the nearest tenth. Find the standard deviation for the following test scores. Use the chart below to record the steps. 85, 100, 92, 96, 87, 94, 75 Difference from Score the Mean (Difference from the Mean) Sum of (Difference from the Mean)* A. Mean: C. Sum of (Difference from the Mean)* divided by (n ): = variance. B. : D. Standard deviation = square root of variance. Standard deviation = E) Explain the mean of set of test scores in a complete sentence. F) Explain the standard deviation of this set of test scores in a complete sentence.
