How to Use This Calculator

Enter up to five numbers in the Value fields (at minimum two values are required for meaningful statistics).
The Mean output is the arithmetic average — the sum of all values divided by the count.
Median is the middle value when the list is sorted; it is less sensitive to outliers than the mean.
Mode shows which value appears most often; 'No mode' is displayed when all values are distinct.
Geometric Mean and Harmonic Mean are specialized averages useful for growth rates and rates-of-change respectively — both require all values to be positive.
Range (max − min) tells you how spread out the data is; pair it with Standard Deviation for a fuller picture.
