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:

  1. 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.

  2. Subtract the mean from each data point. This gives you the deviation of each point from the mean.

  3. Square each deviation. This removes any negative signs and gives more weight to larger deviations.

  4. Find the mean of these squared deviations. This is the variance.

  5. Take the square root of the variance. This gives you the standard deviation.

  6. 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
