standard deviation of -1.55, -1.03, 0, 0.52, 0.77, 1.29
You asked:
Find the sample standard deviation of the following data: \(-1.55, -1.03, 0, 0.52, 0.77, 1.29\)
MathBot Answer:
The sample standard deviation is a measure of the spread of values around the arithmetic mean in a data set. It is the square root of the sample variance, and it is calculated with the formula: \[S = \sqrt{\frac{1}{n-1}{\sum_{i=0}^{n}{(x_i - X)^2}}}\] where \(x_i\) represents the individual values, \(n\) represents the number of values in the data set, and \(X\) represents the arithmetic mean.
The sample standard deviation of \(-1.55, -1.03, 0, 0.52, 0.77,...\) is \(1.09460495156929\).
