Mean, median, and mode are measures of central tendency in statistics. They are used to represent a set of data by a single value that summarizes the data. Here is a brief explanation of each measure:
-
Mean: The mean is the average value of a set of numbers. It is found by adding up all the numbers in the set and then dividing by the total number of values in the set.
-
Median: The median is the middle value when a data set is ordered from least to greatest. If there is an even number of values, the median is the average of the two middle values.
-
Mode: The mode is the value that appears most frequently in a data set. If there are multiple values that appear with the same highest frequency, the data set is said to be multimodal.
These measures are used to describe the central tendency of a data set, but they do not provide information about the spread or variability of the data. To get a more complete picture of a data set, other measures such as range, variance, and standard deviation can be used.
