Correct answer: Range
Explanation:
Measures of central tendency are statistical measures that describe the center of a data set. These include: - Mean: The average of the data set. - Median: The middle value when the data set is ordered. - Mode: The value that appears most frequently in the data set. The range, however, is a measure of the spread or dispersion of the data, not the central tendency. It is the difference between the largest and smallest values in the data set. Hence, the correct answer is Range, as it is not a measure of central tendency.
Find the mean and mode of the following data:
Class | 15--20 | 20--25 | 25--30 | 30--35 | 35--40 | 40--45 |
Frequency | 12 | 10 | 15 | 11 | 7 | 5 |
