Basic statistics involves understanding and analyzing data by using simple measures such as mean, median, and mode. These concepts help us summarize and interpret a set of numbers.

Here’s a quick explanation of these terms:
- Mean: The average of a set of numbers. Add all the numbers and divide by how many there are.
- Median: The middle number in an ordered set of numbers. If there is an even number of values, take the average of the two middle numbers.
- Mode: The number that appears most often in a set. Some sets may have more than one mode or no mode at all.

Examples:

Example 1: Calculating the Mean
Numbers: 4, 8, 6, 10
Step 1: Add the numbers: 4 + 8 + 6 + 10 = 28
Step 2: Divide by the total numbers: 28 ÷ 4 = 7
Answer: The mean is 7.

Example 2: Finding the Median
Numbers: 3, 7, 1, 5
Step 1: Arrange in order: 1, 3, 5, 7
Step 2: Take the average of the two middle numbers: (3 + 5) ÷ 2 = 4
Answer: The median is 4.

Example 3: Identifying the Mode
Numbers: 2, 4, 4, 6, 8
The number 4 appears most often.
Answer: The mode is 4.

Basic statistics helps us understand data patterns and make informed decisions, whether it’s analyzing test scores, survey results, or sports statistics.
