List and Describe the Three Measures of Central Tendency

Question

Examlex · Accepted Answer

The Answer is The three measures of central tendency are mean, median, and mode.

1. Mean: The mean is the average of a set of numbers. It is calculated by adding up all the numbers in the set and then dividing by the total number of values. The mean is useful when you want to find the average value of a data set. For example, if you want to find the average score of a class on a test, you would use the mean.

2. Median: The median is the middle value in a data set when the values are arranged in ascending order. If there is an even number of values, the median is the average of the two middle values. The median is useful when you want to find a value that represents the middle of the data set, especially when there are outliers that could skew the mean. For example, if you want to find the middle income in a group of people, you would use the median.

3. Mode: The mode is the value that appears most frequently in a data set. A data set can have one mode, more than one mode, or no mode at all. The mode is useful when you want to find the most common value in a data set. For example, if you want to find the most popular color in a survey, you would use the mode.

In a situation where the data set is normally distributed and does not have any extreme outliers, the mean would be the best measure of central tendency to use. In a situation where the data set has extreme outliers, the median would be the best measure of central tendency to use. In a situation where you want to find the most common value in a data set, the mode would be the best measure of central tendency to use.
