Analysis

What is the association between education and BMI-pre intervention in adult females in this study?

Based on the variables that I will be using in this study, I will be using independent sample t test.

Summary

The sample in this study is thirty with an average age of 55.27 and standard deviation of 17.14. There are twenty sessions available in this study with an average of 12.10 and standard deviation of 6.32. In this study, the race consists of African American, White, and Latino.
