The mean of a data set is the sum of the elements divided by the number of elements. Add the elements, then divide by 7:
.
15 is not the mean.
The median of the data set with an odd number of values is the value that is in the exact center if the elements are arranged in ascending order. The data set is already as such; the center element is 15, as seen below:
That makes 15 the median.
The mode of the data set is the value that appears most frequently. The only value that appears multiple times is 15, as seen below:
.
That makes 15 the mode.
Statements (b) and (c) are correct, but not Statement (a).
