Given:
Given that the list of students' scores on a quiz.
The list of students' scores are 5, 12 ,7, 15, 20, 14, 7
We need to determine the mode of these scores.
Mode:
The mode of the set of data is the number that occurs most often in the given set of numbers.
Thus, from the data, the number that occurs most often is 7.
The number 7 occurs twice in the given set of data which is the maximum number of occurrence by any other number in the given set of data.
Hence, Mode = 7
Therefore, the mode of these scores is 7.
