Statistics
How to calculate mean?
The mean is the most common way to calculate the “average” of a data set.
- Formula: Mean = Σ(x_i) / n
- Σ (sigma) represents the sum of all the values (x_i) in the data set.
- n represents the total number of values in the data set.
How to calculate median?
The median is the ‘middle’ value when the data is ordered from least to greatest.
- If you have an odd number of data points, the median is the exact middle value.
- If you have an even number of data points, the median is the mean of the two middle values.
How to calculate mode?
The mode is the most frequent value in the data set. A data set can have multiple modes, or even no mode at all if all the values appear an equal number of times.

Introduction of Statistics and its Types
Statistics and its Types: Statistics is a branch of math focused on collecting, organizing, and understanding numerical data. It involves analyzing and interpreting data to solve real-life problems, using various quantitative models. Some view statistics as a separate scientific discipline rather than just a branch of math. It simplifies complex tasks and offers clear insights into regular activities. Statistics finds applications in diverse fields like weather forecasting, stock market analysis, insurance, betting, and data science.
