WebSep 17, 2024 · Step 1: Find the mean To find the mean, add up all the scores, then divide them by the number of scores. Mean (x̅) Step 2: Find each score’s deviation from the mean Subtract the mean from each score to get the deviations from the mean. Since x̅ = 50, here we take away 50 from each score. Step 3: Square each deviation from the mean

WebOct 19, 2024 · Take these two steps to calculate the mean: Step 1: Add all the scores together Step 2: Divide the sum by the number of scores used As an example, imagine that your psychology experiment returned the following number set: 3, 11, 4, 6, 8, 9, 6. To calculate the mean, you first add all the numbers together (3 + 11 + 4 + 6 + 8 + 9 + 6 = 47). WebThe lower the standard deviation, the closer the data points tend to be to the mean (or expected value), μ. Conversely, a higher standard deviation indicates a wider range of values. Similar to other mathematical and statistical concepts, there are many different situations in which standard deviation can be used, and thus many different equations.
