What is an Average?

In mathematics, an average is a single value that represents a group of numbers. It helps us understand data more easily by summarizing it into one figure. There are different types of averages:

  • Mean (Arithmetic Average): Add all numbers together and divide by how many there are.
  • Median: Arrange numbers in order and pick the middle value.
  • Mode: The most frequently occurring number in the dataset.
  • Weighted Average: Some values count more than others (for example, exam grades with different percentages).

FAQs

Q1:What is the difference between mean, median, and mode?

  • Mean is the sum of all numbers divided by the total count.

  • Median is the middle number when values are sorted.

  • Mode is the number that appears most often.

Weighted averages give more importance to certain values. For example, if an exam grade counts for 70% and homework counts for 30%, a weighted average gives you a fairer overall result.
