t test quiz

A t test involves comparing the average between two different groups. For example, a new curriculum was implemented at a middle school in the 2018–2019 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 2018–2019 school year and the previous school year, 2017–2018, as the two different groups. If scores improved, leaders are likely to implement it for the upcoming 2019–2020 school year to continue upward trends in student performance.
