The Answer is The mean of a data set is sometimes one of the data points in a set of data.The mean, or average, of a data set is calculated by summing all the data points and then dividing by the number of data points. It represents the central value of the data set. The mean does not necessarily have to be one of the actual data points—it can be a value that doesn't appear in the data set at all. However, in some cases, the mean can indeed be one of the data points.
Here are two examples to illustrate this:
1. Example where the mean is not one of the data points:
Consider the data set {1, 2, 3, 4, 6}. The mean is calculated as (1 + 2 + 3 + 4 + 6) / 5 = 16 / 5 = 3.2. In this case, the mean (3.2) is not one of the data points in the set.
2. Example where the mean is one of the data points:
Consider the data set {2, 3, 4, 5, 6}. The mean is calculated as (2 + 3 + 4 + 5 + 6) / 5 = 20 / 5 = 4. In this case, the mean (4) is one of the data points in the set.
Therefore, the mean can sometimes be one of the data points, but it is not always the case.
