if you want to use your calc for this you would have to put it in as the operations to change the mixed to improper fraction i.e. input exactly as "((8*3)+6)*((3*7)+1)=" remember? take denominator times whole number plus numerator and put over denominator to convert from mixed to improper... hope this helps

Press 2ND [CSR] to clear the stat data.
For each data point, enter the number followed by SIGMA+
If you have grouped data, enter the number followed by 2ND [FRQ] followed by the frequency then SIGMA+
Press 2ND [sigma x n] for the population standard deviation or 2ND [sigma x n-1] for the sample standard deviation.
