This demonstrates how to use cloud variables to gather statistical information. We use only 3 variables: num, for the number of entries. sum, for the sum of all entries. sq_sum is for the sum of all squared entries. Press space to move through stat displays.
Formulas used: let n be number of entries let xi be the ith entry average = (1/n) * Σ[xi], where i is from 1 to n (for those unfamiliar with big sigma notaiton, this is the same thing as x1 + x2 + x3 + x4 + ... + xn) variance = (1/n) * Σ[xi^2] - (average^2), where i is from 1 to n standard deviation = sqrt(variance)
