A teacher wants to know if a new teaching method improves test scores compared to the standard method.
Problem
Needs to compare the test scores of two different classes to see if the difference is statistically significant.
How to use
Enter the test scores of Class A in Group 1 Values and Class B in Group 2 Values, keep hypothesized difference at 0, and select a two-sided alternative hypothesis.
Group 1: 85, 88, 90, 92, 87
Group 2: 78, 80, 85, 82, 79
Alpha: 0.05Outcome
The calculator outputs the t-statistic and p-value, showing whether the new method resulted in a statistically significant difference in scores.
