Answer 1

Standard Deviation Formula

The standard deviation formula is similar to the variance formula. It is given by:

Standard Deviation Formula The standard deviation formula is similar to the variance formula. It is given by: sigma = squareroot 1/N sigma^N_i = 1 (c = x_i -x^bar)^2 sigma = standard deviation xi = each value of dataset x (with a bar over it) = the arithmetic mean of the data (This symbol will be indicated as mean from now) N = the total number of data points sigma (xi -mean)^2 = The sum of (xi - mean)^2 for all datapoints For simplicity, we will rewrite the formula: sigma squareroot [sigma(x-mean)^2 /N]

σ = standard deviation

xi = each value of dataset

x (with a bar over it) = the arithmetic mean of the data (This symbol will be indicated as mean from now)

N = the total number of data points

∑ (xi - mean)^2 = The sum of (xi - mean)^2 for all datapoints

For simplicity, we will rewrite the formula:

σ = √[ ∑(x-mean)^2 / N ]
