What is Mean?
The mean is the average of the numbers.
For example,
Consider the following numbers: 12, 16, 12, 6, 18, 2, and 4
𝑀𝑒𝑎𝑛 = 𝑆𝑢𝑚 𝑜𝑓 𝑣𝑎𝑙𝑢𝑒𝑠/𝑁𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑣𝑎𝑙𝑢𝑒𝑠
= 12+16+12+6+18+2+4/7 = 70/7 = 10
∴ The mean of 12, 16, 12, 6, 18, 2 and 4 is 10.
What is Median?
The median is the middle value of the list when it’s arranged in ascending order.
For example,
Consider the following numbers:
12, 16, 12, 6, 18, 2, and 4.
The ascending order of these numbers is as follows: 2, 4, 6, 12, 12, 16, 18
12 is the middle value.
∴ The median of this set of values is 12.
What is Mode?
The mode is the value that appears most often in a set of data. For example,
Consider the following numbers:
12, 16, 12, 6, 18, 2, and 4
Here, 12 occurs twice which is the most number of occurrences.
∴ The mode of this set of values is 12.
