Web1 apr. 2024 · Carrying on with the screen time example we will calculate the z score of Monday. To do that we should subtract the mean from our data point and divide it to standard deviation value. For us, it means “2 -3 = -1″. Now we divide -1 to 0,9 which is our standard deviation value, ” -1 /0,9 = -1,1 “. The result is -1,1. speed lifts

How do you find the standard score of a given x-value?

Webstandard scores do, but do so based on a different numerical system with different means and standard deviation units as shown above.
