Solution
To standardize the value of a variable, one has to calculate the Z-score of the variable to make a standard normal curve.
Here are the steps to calculate the Z-score:
-
Find the mean (average) of the dataset. This is done by adding all the data points and then dividing by the number of data points.
-
Subtract the mean from each data point. This gives you the deviation of each point from the mean.
-
Square each deviation. This removes any negative signs and gives more weight to larger deviations.
-
Find the mean of these squared deviations. This is the variance.
-
Take the square root of the variance. This gives you the standard deviation.
-
For each data point, subtract the mean and then divide by the standard deviation. This gives you the Z-score.
The Z-score tells you how many standard deviations a data point is from the mean. A Z-score of 0 means the data point is exactly at the mean. A Z-score of 1.0 means the data point is one standard deviation above the mean. A negative Z-score
