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. 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 …
WebApr 28, 2024 · Subtract the mean from each value in the data set. Square the differences found in step 2. Add up the squared differences found in step 3. Divide the total from step 4 by either N (for population data) or (n – 1) for sample data (Note: At this point, you have the variance of the data) Take the square root of the result from step 5 to get the ... WebLet's take the calculator out. So we get 12 divided by 6.3. It's 1.9 standard deviations. Its z-score is 1.9. Which means it's 1.9 standard deviations above the mean. So the mean is 81, we go one whole standard deviation, and then 0.9 standard deviations, and that's where a score of 93 would lie, right there. Its z-score is 1.9. And all that ...
