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 WebThe standard deviation is 0.15m, so: 0.45m / 0.15m = 3 standard deviations. So to convert a value to a Standard Score ("z-score"): first subtract the mean, then divide by the Standard Deviation. And doing that is called "Standardizing": We can take any Normal Distribution and convert it to The Standard Normal Distribution.
