Final answer:
The median is a number that measures the center of the data, while the mode is the most frequent value. The mean is calculated by adding all the values and dividing by the number of values. The correct option is a) Median
Step-by-step explanation:
The median is a number that measures the center of the data. It separates the ordered data into halves, where half the values are the same number or smaller than the median, and half the values are the same number or larger. For example, if we have the data set {1, 2, 3, 4, 5}, the median would be 3 because it separates the data into two equal parts.
The mode is the value that appears most frequently in a set of data. For example, in the data set {1, 2, 2, 3, 4, 4, 4, 5}, the mode would be 4 because it appears more frequently than any other value.
The mean (also known as the average) is another measure of the center of the data. It is calculated by adding up all the values in the data set and then dividing by the number of values. For example, if we have the data set {1, 2, 3, 4, 5}, the mean would be (1+2+3+4+5)/5 = 3.
The correct option is a) Median
