Answer :
action of departing from an established course or accepted standard.
There's mean deviation and standard deviation.
Mean Deviation: The average distance to the mean.
Standard deviation = Square root of variance
-----------------------------------------------------------------
Standard deviation formula:
[tex]\sigma =\sqrt { \frac { \Sigma { x }^{ 2 } }{ n } -{ \left( \frac { \Sigma x }{ n } \right) }^{ 2 } } [/tex]
Mean Deviation: The average distance to the mean.
Standard deviation = Square root of variance
-----------------------------------------------------------------
Standard deviation formula:
[tex]\sigma =\sqrt { \frac { \Sigma { x }^{ 2 } }{ n } -{ \left( \frac { \Sigma x }{ n } \right) }^{ 2 } } [/tex]
