Measures of Central Tendency

Measures of central tendency are statistical values that represent the center or typical value of a data set. The three most commonly used measures of central tendency are the mean, median, and mode.

1. Mean: The mean is the arithmetic average of a data set. To calculate the mean, you add up all the values in the data set and divide by the number of values. For example, if you had the following data set: 2, 4, 6, 8, 10, the mean would be (2+4+6+8+10)/5 = 6.

The mean is a useful measure of central tendency when the data set is normally distributed, meaning it has a symmetrical bell-shaped curve. However, the mean can be heavily influenced by extreme values, or _______ ________ ________ _____ _________ _________ __________ __________.
