How it works

The list is sorted for median and range, summed for mean, and counted for modes. The median is the centre or average of the middle pair; modes tie at the greatest frequency.

  • The list is treated descriptively without a distribution assumption.
  • A value occurring once is not treated as a meaningful mode.

Worked example

Dataset Summary
Calculate statistics for a dataset of sales figures
Input
											120, 150, 130, 150, 180, 110, 145
Output
												Count: 7
Sum: 985
Mean: 140.71428571428572
Median: 145
Mode: 150
Min: 110
Max: 180
Range: 70

When to use this

Classroom datasets summarize centre, surveys identify common responses, and quality reports compare median with mean under skew.

Edge cases

  • An outlier can move mean more than median.
  • Several values can tie as modes.
  • An empty or nonnumeric list cannot produce statistics.
