Calculate mean, median, mode, and range for any set of numbers
Statistical averages help us understand and summarize data sets by finding central tendencies and spread. Each measure provides different insights into your data, making them valuable for analysis in various fields including education, business, science, and everyday decision-making.
The mean is the sum of all values divided by the count of values. It's the most commonly used average.
The median is the middle value when data is sorted. If there's an even count, it's the average of the two middle values.
The mode is the value that appears most frequently. A dataset can have one mode, multiple modes, or no mode.
The range is the difference between the maximum and minimum values, showing the spread of your data.
Your data is normally distributed without extreme outliers. The mean is sensitive to every value, making it ideal for evenly distributed data like test scores or measurements.
Your data has outliers or is skewed. The median is resistant to extreme values, making it better for income data, housing prices, or any dataset with significant outliers.
You need to find the most common value. The mode is useful for categorical data, finding popular choices, or identifying the most frequent occurrence in your dataset.
