Mean = (Sum of the numbers) ÷ (The number of numbers)
2. Median is the middle number which is obtained after arranging the group of numbers in either ascending or descending order. [And if there are even number of numbers, then take the mean of the two middle numbers.]
Median = {(n + 1) ÷ 2}th, where “n” is the number of items in the set and “th” means the (n)th number.
3. Mode is the number that appears most often or most frequently in a set of numbers.
The only way to find out the mode is by making a frequency table through which the most frequent number can be obtained.
