9: CHAPTER TWO SAMPLE TESTS WITH NUMERICAL DATA Grown-ups love figures. ... Only from these figures do they think they have learned anything. The Little Prince Advantages of non-parametric methods: 1. Quick and easy 2. Require few assumptions 3. Can be used on nominal and ordinal data as well as ratio and interval data. Disadvantages: 1. Less efficient (since they do not use all the information) 2. Less powerful when parametric methods are appropriate. Example 1: Does increasing calcium intake reduce blood pressure? Observational studies suggest that there is a link, and that it is strongest in African-American men. Twenty-one African-American men participated in an experiment to test this hypothesis. Ten of the men took a calcium supplement for 12 weeks while the remaining 11 men received a placebo. Researchers measured the blood pressure of each subject before and after the 12-week period and the data is in pooledt.xls. Is there a decrease in the blood pressure after taking calcium? Example 2: The dataset pairedt.xls contains labor the force participation rate (LFPR) of women in 19 cities in the United States in each of two years (1968 and 1972). The data help to measure the growing presence of women in the labor force over this period. Compare LFPR rates in the two years. Example 3: The price of fish varies by species and time (see fishprc.xls). The average price received by fishermen and vessel owners for several species of fish increased from 41 cents per pound in 1970 to \$1.10 per pound in 1980. Is this increase significant? Example 4: Seven people between the ages of 15 and 25 and six people between the ages of 45 and 60 were random...
