Applied Data Analysis: ANOVA on anorexia The next data to analyze is a data set on anorexia and is from the source quoted belowi. There is an "anorexia.csv" in the directory Supplementary Materials under the Content tab. If however, you have installed R on your computer, it is available by first typing: > librarylMASS] > anorexia Anorexia is an eating disorder and the data consists of three treatments for it: a control (Cont), cognitive behavioral treatment {CST}, and family treatment {FT}. The response measured are the patients weight prior to treatment (Prewtl and patients weight after the treatment [Postwt}. Our interest is in difference in weight {Postwt - Prewt} after each treatment across the three treatments. Use ANOVA to test the null hypothesis that all treatments are the same. You can perform the data analysis either by using a scientific calculator, using spreadsheet features, or, you can do this completely in R [some guidance will be provided on this weeks Discussion}. 1.
