📝 What is the Statistics Calculator?
Imagine you ask 10 friends how much pocket money they get. You will have a list of different numbers. Statistics is a way to find patterns in those numbers.
Our Statistics Calculator does all the hard math for you. You just paste your list of numbers, and it instantly calculates the “Average” (Mean), the “Middle Number” (Median), and the “Most Common Number” (Mode). It even calculates harder things like Variance and Standard Deviation to show how spread out your data is. Plus, it draws a cool bar chart!
🧮 How Statistics Calculator Works?
To give you the correct answer, we use standard math formulas found in the code.
1. Mean (Average):
2. Variance ():
This measures how far each number is from the average.
3. Standard Deviation ():
This is the most common way to measure “spread” or “risk.”
The tool does these complex steps for you automatically.
