What This Document Is
This document contains a homework assignment (Homework 3) for Intro to Statistics (STA 144) at California Baptist University, assigned on July 23, 2022, by Professor Ogbochi A. Mckinney. It focuses on applying statistical concepts covered in Chapters 5 and 6.
Why This Document Matters
This assignment is intended for students enrolled in STA 144. It serves as a practice opportunity to reinforce understanding of correlation analysis, scatterplots, and coefficient of determination—key topics in introductory statistics. Successful completion contributes to the overall course grade.
Common Limitations or Challenges
This document *is* the assignment itself. It does not provide instruction on *how* to perform the statistical analyses. Students are expected to have learned these methods in class and utilize statistical software (SPSS is specifically mentioned) to complete the tasks. It also doesn't offer solutions or explanations.
What This Document Provides
The homework includes five main problems involving: calculating Pearson correlation coefficients using SPSS, interpreting scatterplots, ranking correlation strengths, correlating variables (exercise minutes with GPA), and determining the coefficient of determination. Data sets are referenced (Chapter 5 Data Sets 2, 3, 5, and 6) and are either included directly or available in an appendix. The assignment also includes example SPSS output tables.
