Step-by-Step Statistics

Location Statistics

See the steps for finding the expected value, or mean:

average of {1, 2, 3, 4, 5, 6, 7}
mean of {x, 2x, 3x, 4x, 5x}

Find the median step by step:

median {5, 3, 2, -4, 7, 1}

Learn how to calculate the mode:

mode of {1, 5, 4, 2, 3, 4, 5, 11, 4, 11, 20}

Calculate and simplify the geometric mean one step at a time:

geometric mean 4, 2, 1, 6

Order Statistics

Apply basic formulas in order statistics on a set of data, seeing the steps along the way:

quartile of {1, 2, 3, 4, 5, 6}
step by step 3rd quartile {8, 7, 6, 56, 7, 7, 8, 89}
find the range of 2, 5, 9, 15, 7, 4, 12, 3, 9

Dispersion Statistics

Find and learn to compute variance and standard deviation:

variance 4, 6, 7, 9, 10, 11
standard deviation -3, 2, -39, 1, 9, 11, 5

Get the steps for how to find the range of a set of numbers:

range of {8, 7, 6, 56, 7, 7, 8, 89}
