    This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

    Only for above listed OTA
    1 set of information with a) solving for sd using conceptual formula and b)solving for sd using computational formula.
    Information:
    Mean:37/6=6.17
    Median:31
    Mode:27
    From the Raw data which is:
    14,16,16,16,20,20,20,21,23,23,24,24,26,27,27,27,27,30,31,31,32,33,34,34,35,35,35,37,38,38,39,42,46,48,49,52,55)
    Frequency table has 6 classes starting @ 0.
    a) s^2 = Sumf (x-mean)^2 / n-1 Use to find standard deviant using conceptual formula
    b) Compute varience of f table using computational version of formula s^2 = n*Sumf*x^2-(Sumf*x)^2 /n(n-1)Use this to find standard deviation
    What do you notice either formula that is used?
