An experiment was conducted to compare two methods of teaching spelling to children. Method 1 and Method 2. The objective of the experiment is to estimate the difference between , the mean score on a standardized spelling test for all children taught by Method 1 and , the mean score on the same test for all children taught by Method 2.

Any two-valued independent variable can be included in a simple or multiple regression analysis. The regression can be used to compare the means of the two groups . yielding the same conclusion as the equal-variances independent groups t-test. Example: Suppose the performance of two groups trained using different methods is being compared.

Here t* is the value for density curve with area C between –t* and t*. To test the hypothesis ,compute the pooled two-sample t statistic. In terms of a random variable T having the t( distribution, the P-value for a test of against . is P() is P() is 2P() Example 5. Take Group 1 to be the calcium group and Group 2 to be the placebo group.

To see the results of the t-test for the difference in the two means, find the p-value for the test. The p-value is labeled as “Sig.” in the SPSS output (“Sig.” stands for significance level). To find the correct “Sig.”, look in the section of the “Independent Samples Test” output labeled “t-test for Equality of Means” and you will find a column labeled “Sig. (2-tailed).”
