A t test involves comparing the average between two different groups. For example, a new curriculum was implemented at a middle school in the 2018â€“2019 school year in hopes of improving standardized test scores. To determine whether there was a difference in scores, leaders will conduct a t test using the data from the 2018â€“2019 school year and the previous school year, 2017â€“2018, as the two different groups. If scores improved, leaders are likely to implement it for the upcoming 2019â€“2020 school year to continue upward trends in student performance.
