Math Tutor | Dvd Statistics Vol 7

The course by Math Tutor DVD focuses specifically on advanced hypothesis testing, with a heavy emphasis on the F-Distribution and Analysis of Variance (ANOVA) .

These fields rely heavily on proportions. Market research (business), survey analysis (psychology/sociology), and public health (epidemiology) demand proficiency in proportion tests. This DVD aligns perfectly with the second half of a semester-long course. math tutor dvd statistics vol 7

The course focuses on the mathematical tools needed to compare the means of more than two populations: The F-Distribution The course by Math Tutor DVD focuses specifically

[ z = \frac(\hatp_1 - \hatp_2) - (p_1 - p_2)\sqrt\hatp(1-\hatp)\left(\frac1n_1 + \frac1n_2\right) ] Where ( \hatp = \fracx_1 + x_2n_1 + n_2 ) (pooled proportion) survey analysis (psychology/sociology)
