Calculating Median and MeanDefinitions•Mean: The average of a set of numbers, calculated by dividing the sum of all numbers by the total count of numbers.•Median: The middle value in a set of numbers when they are arranged in ascending or descending order. If there is an even number of observations, the median is the average of the two middle numbers.How to Calculate Mean1.Sum all the numbers in the set.2.Divide by the count of numbers in the set.Formula:Example:Calculate the mean of the numbers: 4, 8, 6, 5, 3.1.Sum: 2.Count: 53.Mean:How to Calculate Median1.Arrange the numbers in ascending order.2.If the count is odd, the median is the middle number.3.If the count is even, the median is the average of the two middle numbers.Example:Calculate the median of the numbers: 4, 8, 6, 5, 3.1.Arrange in ascending order: 3, 4, 5, 6, 8.2.Count: 5 (odd), so the median is the middle number (3rd position).3.Median: 5.Example with Even Count:Calculate the median of the numbers: 4, 8, 6, 5.1.Arrange in ascending order: 4, 5, 6, 8.2.Count: 4 (even), so the median is the average of the 2nd and 3rd numbers.
3.Median:Summary•Mean: Add all numbers and divide by the count.•Median: Arrange numbers and find the middle value (or average of two middle values if even).These calculations are fundamental in statistics and help summarize data effectively.
