1.What does it meanfor a sample to have a standard deviationof zero? Describe the scores in such a sample.

2. A population has mean, M =100 and standard deviation, s = 20. If you select a single score from this population, on the average, how close would it be to the population mean? Explain answer.

1. What does it mean for a sample to have a standard deviation of zero? Describe the scores in such a sample.

If the standard deviation is zero, it means that all the values in the sample are equal. The scores in such a sample are all equal such as 47, 47, 47, 47, 47, – – – – – -, 47.
