Ateacher writes the results of a test on the board: 7 students received a’s, 10 students received b’s, 18 students received c’s, 4 students received d’s and 1 student received an f. the grade of c would represent which measure of central tendency?

mode

Explanation:

The mode is the most common value in a data set. In this case, the frequency distribution was 7 A's, 10 B's, 18 C's, 4 D's and 1 F, since C is the most common grade, it is the mode.

Only if this was a normal distribution, the mode should be equal to the mean and the median. In this case the median is also C (the number in the middle), but if we assign numbers to the grades (A=5, B=4, C=3, D=2 and F=1) the mean = 3.45.

The measure of central tendency that grade C represents is the Mode.

From the given question, the frequency distribution is as follows:

7 A's, 10 B's, 18 C's, 4 D's and 1 F

C is the mode because it is the value that occurs most (common grade) in the set of data.

Thus, the central tendency that grade C represents is Mode.

Central of tendency refers to a summary of a set of data through a single value that identifies the center position in the given data.

A measure of central tendency is an attempt to describe the central position of a set data. The central tendency does not provide details as to the single value in data distribution, it only provides a descriptive summary of the all the values in a data set.

However, the three measures of central tendency include:
