The document describes conducting a one-way ANOVA to analyze the average IB grades between two different IB classes. It provides the hypotheses, data collection process, data tables for each class, a normal distribution check, and the ANOVA calculation and results in Excel. The ANOVA analysis found no significant difference between the average IB grades of the two classes, as the p-value was greater than 0.05 and the F-value was less than the critical F-value.
