Mean is simply described the average. Mean is sum of all the given numbers & divided by number of numbers. Mode can be calculated by finding the highest repeated numbers in the series. If each number in the set occurs the same number of times, the set of data has no mode. The given numbers can have more than one Mode. Median is the Middle value of the given set of numbers which is where the given set of numbers are arranged in ascending order. For calculating the median we use separate formula odd entries as well as for Evan entries. After sorting the list in the increasing order, If the list has an odd number of entries, the median is the middle entry in the list. If the list has an even number of entries, the median is equal to the sum of the two middle (after sorting) numbers divided by two.This worksheet help you to understand how to compute mean, median and mode from the given set of data.
Formula to calculate mean:
Mean = Sum of X values / N(Number of values) (or)
Mean, Median, Mode Example:
Find the mean, median & mode for 5,20,20,50,40?
To Find Mean
Mean = (5 + 20 + 20 + 50 + 40)/5
= 135/5
= 27
To find Median
Now arrange the above set of data in ascending order.
5,20,20,40,50
The middle value of the above data set is 20, therefore median is 20.
To find Mode
In the given values 20 is repeated. Hence mode is 20.
When you try such calculations on your own, this mean, median mode calculator can be used to verify your results.
