598 Chapter 20 ested in the magnitude of the difference between the means, not its direction or sign (plus or minus). We are only interested here, then, in the absolute value of t, 6.844. Looking at the values in appendix C, we see that any t-value above 3.291 is significant for a two-tailed test at the .001 level. Assuming that our samples represent the populations of American students and Liberian students, we’d expect the observed difference in the means of how many children they want to occur by chance less than once every thousand times we run this survey. Analysis of Variance A t-test measures the difference between two means. Analysis of variance, or ANOVA, is a technique that applies to a set of two or more means. Table 20.3 shows the scores for four groups of states in the United States on the percentage of teenage births in 1996. Each group of states has a mean percentage of teenage births. The question we want to answer is: Are the differences among the means significantly different, at say, the .05 level? To answer this question we will calculate the ratio of the between-group variance, s 2 between, to the within-group variance, s 2 within. The between-group and within-group variances sum to the total variance, s 2 . We already know, from chapter 19, the formula for the total variance. Here it is again: 2 xx s 2 Formula 20.3 n1 where x represents the raw scores in a distribution of interval-level observations, x is the mean of the distribution of raw scores, and n is the total number of observations. So, to find the variance in a distribution: (1) subtract each observation from the mean of the set of observations; (2) square the difference (thus getting rid of negative numbers); (3) sum the squared differences (this is called the sum of the squares); and (4) divide that sum by the sample size, minus 1. 2 The variance is calculated from the sum of the squares,xx . Here is the formula for calculating the sum of the squares directly from the data in table 20.3: x 2 2 x n Formula 20.4
