💡 Learning Objectives
 Describe what the Chisquare Tests are and how they work
 Calculate Chisquare tests
 Describe and calculate a onesample z test
 Calculate ttest and ANOVA by hand
 Articulate how the equations for all tests relate to what we’ve discussed about model building previously
💪🏿 This is what I accomplished my sixth week in the DTSC 550 course:
📘 Chapter 12 goes over:
 Categorical Analyses
📘 Chapter 13 goes over:
 Comparing Two Means
📘 Chapter 14 goes over:
 Comparing More than Two Means
📺 Videos watched (some videos have a 1 question quiz at the end):

ANOVA Introduction

ANOVA Part 2: Math

Multiple comparisons

ANOVA Practice Problems

tTest Practice Problems: I was given four different datasets and I had to calculate the tstatistic by hand, calculate the degrees of freedom, determine the critical tvalue, interpret the results

ANOVA Practice Problems: I needed to figure out which hypothesis is supported, calculate the total sum of squares, calculate the model sum of squares, calculate simple linear regression, compute degrees of freedom, calculate mean squares, calculate F value, find critical value
💯 Exam
 Module exam had 21 questions: fill in the blank, true/false, and multiple choice with one answer. It was heavy on true/false which was nice. This test looked easy but was difficult even with the true/false questions. Tricky wording! No calculations using R in R Studio.
 You can take the exam as many times as needed to get the score you want, but each test has different questions. I took the exam 5 times. Final score was 87.04%. You have until the end of the semester to take all your exams.
🔥 Summary
 I really enjoyed the practice problems since last week didn’t have any. This week had a short test, but could have been longer for reinforcement.
