In Table 4.9, we see that the mean is higher for the girls than for the boys. The obtained value is greater than the critical value in this test, so we reject the null. This independent t-test has significance. In Table 4.10, an independent t-test is performed to examine the post-test differences between the girls and the boys in literature.
