Explore the Distributions - ( You can type in any multiples of " c " into the frequency for RV Sigma, but multiples of two have certain steps ) c*.4 or c*.8 are o.k. -- Somehow " A " has become fixed - must have happened during some changes! ( student frequencies have become fixed by accident ) see my other worksheet " student " for frequency of purple equation. student - 3 degrees of freedom - Type 5 and Type 6 Pearson's Curve ( Refer to Citing below for information on this " name and works " ) Normal - 1 degree of freedom RV Sigma - 2 degrees of freedom - Type 10 Pearson's Curve The Probable Error of a Mean (Citing ) Author(s): Student Source: Biometrika, Vol. 6, No. 1 (Mar., 1908), pp. 1-25 Published by: Biometrika Trust Stable URL: http://www.jstor.org/stable/2331554 Accessed: 11/12/2009 10:55
You can model the distributions and see the differences between them. Explore Frequencies( M ) for RV sigma are to be type in in multiples of 2*c or c or c/2 2c*2*2 or 2c /2 *2 *2 , etc.
