Frequently Asked Questions
How to calculate average?
Add up all the numbers and divide by how many numbers there are. This gives you the mean (average). Formula: Average = Sum / Count.
What is the difference between mean, median and mode?
Mean is the average of all numbers. Median is the middle value when sorted. Mode is the most frequently occurring number.
How to find median?
Sort the numbers from smallest to largest. If odd count, median is the middle number. If even count, median is the average of the two middle numbers.
