**Explanation for Educational Purposes:**
This exercise involves calculating the mean and standard deviation for three different samples, each with three data points. The samples are chosen to have the same spread but different mean values. The purpose is to demonstrate whether standard deviation is dependent on the mean value of a data set.
Standard deviation measures the amount of variation or dispersion in a set of values. The higher the standard deviation, the more spread out the values are. This exercise helps clarify if and how the mean value impacts standard deviation, which is critical to understanding statistical variability.
