Question

Quizplus · Accepted Answer

The results given by the teacher represent the frequency distribution of the test scores among the students. Therefore, the correct option is C, frequency distribution. Measures of central tendency (such as mean, median, and mode) and variability (such as range, variance, and standard deviation) require additional numerical data beyond the given frequencies. A correlation table requires pairs of numerical data for each student, which are not provided in the given information.
