stdDev( ) MATH/Statistics menu stdDev(list[, freqlist]) ⇒ expression Returns the standard deviation of the elements in list. stdDev({a,b,c}) ¸ stdDev({1,2,5,ë 6,3,ë 2}) ¸ Each freqlist element counts the number of consecutive occurrences of the corresponding element in list. Note: list must have at least two elements. stdDev({1.3,2.5,L6.4},{3,2,5}) ¸ 4.33345 stdDev(matrix1[, freqmatrix]) ⇒ matrix Returns a row vector of the standard deviations of the columns in matrix1. Each freqmatrix element counts the number of consecutive occurrences of the corresponding element in matrix1. stdDev([1,2,5;-3,0,1;.5,.7,3]) ¸ [2.179... 1.014... 2] stdDev([L1.2,5.3;2.5,7.3;6,L4],[4,2;3 ,3;1,7]) ¸ [2.7005,5.44695] Note: matrix1 must have at least two rows. stdDevPop( ) MATH/Statistics menu stdDevPop(list[, freqlist]) ⇒ expression Returns the population standard deviation of the elements in list. Each freqlist element counts the number of consecutive occurrences of the corresponding element in list. Note: list must have at least two elements.
