SEE THIS EXAMPLE. ADD THEM ALL UP AND DIVIDE THE RESULT BY THE NUMBER OF TERMS, WHICH ARE 10 HERE:

Statistical file:
{11, 23, 24, 35, 54, 56, 76, 21, 13, 19}

 


Average (mean): μ=33.2
Absolute deviation: 176.4
Mean deviation: 17.64
Minimum: 11
Maximum: 76
Variance: 422.76
Standard deviation σ=20.5611283737
Corrected sample standard deviation s=21.673332308
Median: 23.5
Mode: {35, 54, 56, 76, 24, 23, 13, 19, 21, 11} - multimodal
Geometric mean: 27.5658344385
Harmonic mean: 23.183959497
Sum: 332
Sum of absolute values: 332
