Statistical treatments are techniques utilized to analyze and interpret data. Some of the most commonly used statistical treatments include t-tests, ANOVA, chi-square, and regression analysis. T-tests determine if two sets of data means are significantly different, while ANOVA analyzes differences between three or more groups. Chi-square determines significant associations between two categorical variables, while regression analysis determines the relationship between a dependent variable and on...

1. Do students at UT spend more time on homework per week in college than they did in high school? For the first question, I ran a one-tailed dependent t-test that was dealing with the amount of homework per week that a student studied in high school and college. Since it was a dependent test, and the question mentions “more”, we want to make the alternative hypothesis include a greater than sign. The null hypothesis for this dependent t-test is that the amount of hours spent on homewo...
