Introduction to Mean, Median, and Mode
In statistics, the mean, median, and mode are fundamental measures of central tendency that help you understand a dataset. Each of these measures provides a different way to summarize and interpret data.
What is the Mean?
The mean is the average of a set of numbers. To calculate the mean, add up all the numbers and then divide by the count of numbers. It's commonly used to find the overall average value in a data set.
Formula: Mean = (Sum of all values) / (Number of values)

What is the Median?
The median is the middle value in a sorted list of numbers. If there is an odd number of values, the median is the middle number. If there is an even number of values, the median is the average of the two middle numbers.
Formula: Median = Middle value of a sorted dataset
What is the Mode?
The mode is the value that appears most frequently in a dataset. A dataset can have one mode (unimodal), more than one mode (multimodal), or no mode at all if no value repeats.
Formula: Mode = Most frequent value in the dataset
