digital statistical calculator

Statistics such as sum, mean, maximum, minimum, population variance, sample variance, median, etc. of statistics

This tool only supports numbers, other characters will be ignored.

Explanation of commonly used statistical items: (Take the numerical list 1, 2, 3, 4, 5 as an example)

  • The sum of all numbers.
sum = 1+2+3+4+5
  • Average: Sum of all numbers divided by number of numbers
    • avg = (1+2+3+4+5)/5
  • The highest of all numbers.
    • max = 5
  • The smallest of all numbers.
    • min = 1
  • Sample variance: Sum of squared differences between each data point and the mean, divided by the number of digits minus one
    • variance = ((1-3)^2+(2-3)^2+(3-3)^2+(4-3)^2+(5-3)^2)/(5-1)
  • Population variance: Sum of squared differences between each data point and the mean, divided by number of digits
    • variance = ((1-3)^2+(2-3)^2+(3-3)^2+(4-3)^2+(5-3)^2)/5
  • The number in the middle of an ordered set of data.
    • median = 3
