Answer:
Option B) Mode is correct
The grade C represent the measure of central tendency is Mode
Explanation:
Given that "A teacher 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."
To find the grade of C would represent which measure of central tendency:
The mode is the most occurring value in a data set.
In the given 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,therefore it is the mode.
Only if the given was a normal distribution, the mode must be equal to the mean and the median.
In this case the median(middle term) is also C .
Hence C is the mode because it is the value that occurs most in the given set of data.
∴ the measure of central tendency for grade C represents is Mode.
