How the Calculation Works (Simple Explanation)
Let’s understand these math terms quickly and easily. These ideas help us describe a group of numbers and are often used in school, business, and daily life.
Mean (Average)
The mean is what most people call the average.
You find it by adding all the numbers together, then dividing by how many numbers you have.
It helps you understand the overall value of the data.
Median (Middle Number)
The median is the middle value in a list of numbers.
First, arrange the numbers from smallest to largest. The number right in the centre is the median.
If there are two middle numbers, just add them together and divide by two.
The median is useful because it shows the centre of the data without being affected too much by very big or very small numbers.
Mode (Most Common Number)
The mode is the number that appears more often than any other in the list.
It helps you see which value is the most popular or most frequent.
Some lists may have more than one mode, and some may have none at all.
Range (Spread of Numbers)
The range tells you how spread out the numbers are.
To find it, subtract the smallest number from the largest number.
A small range means the numbers are close together. A large range means they are more spread out.
Together, mean, median, mode, and range give a simple but powerful summary of your data.
Example
Numbers: 2, 4, 4, 6, 8
- Mean: (2 + 4 + 4 + 6 + 8) = 24 → 24 ÷ 5 = 4.8
- Median: The middle number is 4
- Mode: 4 (it appears twice)
- Range: 8 − 2 = 6
The calculator does all of this in one click.

FAQs
What is the difference between mean and median?
The mean is the average of all numbers. The median is the middle number after sorting. Median is better when numbers are very uneven.
Can there be more than one mode?
Yes. If two or more numbers appear the same number of times, the data can have multiple modes.
What if all numbers appear only once?
Then there is no mode, because no number repeats more than the others.
Do I need to sort numbers before entering them?
No. The calculator automatically arranges the numbers to find the median and other values.
Can I use decimals or negative numbers?
Yes. You can enter whole numbers, decimals, and negative numbers.
