A researcher aims to evaluate the effect of aerobic exercise training on Peak Expiratory Flow Rate (PEFR) in healthy young men. He recruited twenty healthy male students aged 18-21 years. The subjects participated in a 16 weeks aerobic exercise plan. The PEFR was recorded in Liter Per Minute (l/min) before the commencement of training and at the end of training. We want to examine whether the difference in the PEFR is just chance variation or not. Suppose that we observe the results in Table 1 (see the last page) from SAS when we analyzed our data using the UNIVARIATE procedure.
