How to Determine the Mean Score

Initially, even the basics of statistics can be confusing. Once you get past the technical wording and equations, however, statistics becomes much easier. The mean score is the same thing as the average score.

Things You'll Need

• Calculator
• Paper
• Pen

Instructions

1. Write each score on a piece of paper, making sure there are no duplicates. Count how many individual scores there are and record this number. Label it "n."

2. Calculate the sum of the scores, and record this number. Label the number "sum." Sometimes the word sum is denoted by the Greek uppercase letter Sigma.

3. Divide the sum of the scores by the count of individual scores, n. Record this number, and label it "mean."

Tips & Warnings

• Be sure to double-check your numbers to ensure accuracy. Label all numbers and calculations for easier revision and checking. Cross out scores as they are summed to prevent using a single score twice.
