What is the mode of this set of data: 78, 79, 80, 80, 89, 89, 92, 93, 94, 95, 95, 95?

A. 80
B. 89
C. 79
D. 95

Answer :

Final answer:

The mode of the provided data set is 95, as it appears with the highest frequency, occurring three times.

Therefore correct option is D

Explanation:

The student has asked to find the mode of the data set: 78, 79, 80, 80, 89, 89, 92, 93, 94, 95, 95, 95. The mode is a measure of central tendency which represents the most frequently occurring value(s) in a data set. Upon examining the data set provided, we can count the frequency of each value:

  • 78 occurs once
  • 79 occurs once
  • 80 occurs twice
  • 89 occurs twice
  • 92 occurs once
  • 93 occurs once
  • 94 occurs once
  • 95 occurs three times

Since the value 95 occurs three times, which is more frequent than any other number in the set, the mode of this data set is 95.
