| The angle between two intersecting planes in three dimensions is the quantity of normal vector of plane A dot normal vector plane B all over the quantity the magnitude of normal vector A times the magnitude of normal vector B. The line of intersection of planes A and B is given by an equation ax+b=cy+d=ez+f. The yates test is only accepted if Chi-squared is less than Chi-squared*. Chi-squared is found through sigma of (expected frequencies - observed frequencies)squared over the expected frequencies. Chi-squared* is observed by looking up the Chi-squared distribution graph under the coordinates (degree of freedom, 1 - significance level). I won't go on. In fact, I may well never need to. Because it's finally over. Two hour paper 1 exam. Three hour paper 2 exam. Forty-five hours in continuous wake. And now it feels like so long ago. |
