Results
The average of all values. Add all numbers and divide by the count.
The middle value when numbers are sorted. If there's an even count, it's the average of the two middle values.
The value(s) that appear most frequently. There can be multiple modes or no mode at all.
The difference between the largest and smallest values. Shows the spread of data.
Statistical Definitions
Mean
The arithmetic mean is calculated by adding all values in a data set and dividing by the number of values. It represents the central tendency of the data.
Median
The median is the middle value in a sorted data set. For an even number of values, it is the average of the two middle numbers. It is less affected by outliers than the mean.
Mode
The mode is the value that appears most frequently in a data set. A data set may have one mode, multiple modes, or no mode if all values appear with equal frequency.
Range
The range measures the spread of data by calculating the difference between the maximum and minimum values. A larger range indicates more variability in the data.
