Given the following Data Set: 9, 3, 2, 7, 8, 2, 4, 1, 5, which measure of central tendency is equal to 2?

  1. Mean

  2. Mode

  3. Median

  4. Range

The correct answer is: Mode

The measure of central tendency that is equal to 2 in the provided data set is the mode. The mode is defined as the value that appears most frequently in a data set. In this case, the number 2 occurs twice, while all other numbers appear only once. To further understand the context of central tendency, the mean is calculated by adding all numbers together and dividing by the count of numbers, which will yield a different value. The median, which is the middle number when the data set is arranged in ascending order, would result in yet another value. Lastly, the range describes the difference between the largest and smallest numbers, providing a measure of dispersion rather than a measure of central tendency. Therefore, among the options, the mode accurately represents the value 2 as the most frequent occurrence in the data set.
