Start with x=75 and add four x values to make a smaple of five data such that the standard deviation of these data equals 0.

If there is no deviation from the mean, all scores = the mean.

still confused....

To create a sample of five data points with a standard deviation of 0, we must have all the data points equal to each other.

Starting with x = 75, we would need to find four more values that are equal to 75.

Therefore, the sample of five data points with a standard deviation of 0 is:

75, 75, 75, 75, 75
