Analysis of Variance Lecture 11 April 26th‚ 2011 A. Introduction When you have more than two groups‚ a t-test (or the nonparametric equivalent) is no longer applicable. Instead‚ we use a technique called analysis of variance. This chapter covers analysis of variance designs with one or more independent variables‚ as well as more advanced topics such as interpreting significant interactions‚ and unbalanced designs. B.

A price control is either a price ceiling or a price floor. Essentially a law is passed that controls a maximum a product can sell for (price ceiling) or the minimum a product can sell for (price floor). A negative effect of a price ceiling‚ for example on prescription drugs‚ would be that drug companies would possibly produce less than they currently do because it wouldn’t be cost effective to make more. With the economy on the downward slope there has been a lot of discussion on the rising price
