Mean, Median & Mode - Measures of Central Tendency - Medical Statistics Made Easy
Mean, median, and mode are all measures of central tendency used to describe the typical or central value of a set of data. This video is a part of the medical statistics made easy series by Edusurg Clinics.
Mean: The mean is the average value of a set of numbers. To find the mean, you add up all the numbers in the set and divide by the total number of values. For example, the mean of the numbers 2, 4, 6, and 8 is (2+4+6+8)/4 = 5.
Median: The median is the middle value in a set of numbers when they are arranged in order. To find the median, you first need to order the numbers from smallest to largest. If there is an odd number of values, the median is the middle value. If there is an even number of values, the median is the average of the two middle values. For example, the median of the numbers 2, 4, 6, and 8 is (4+6)/2 = 5.
Mode: The mode is the value that appears most frequently in a set of numbers. A set of data can have one or more modes, or it can have no mode at all. For example, the mode of the numbers 2, 2, 4, 6, and 8 is 2.
These measures of central tendency are useful for summarizing large amounts of data and providing a single value that represents the typical value of a dataset. However, they have limitations and should be used in conjunction with other statistical measures to fully describe a dataset.
