The Chi-Squared Distribution is graphed below in RED. It is shown as the degrees of freedom, df, changes from df=2 to df=51. Also included are three normal curves for comparison. The means and standard deviations of the normal curves have been selected to show a curve close to the Chi-Squared curve at representative values for df. The normal curves are: mean=5 with standard dev = 3.3, mean = 30 with standard dev=8, and mean=50 with standard dev=10. The Chi-squared Curve should be automatically animated. If it is not, right click on the df and select animate.
How does the Chi-Squared Distribution compare to the normal curve as the df increases? Prof. G. Battaly
