Q2 Describe regression analysis in your own words.

Hint: A correct answer must have a discussion on a main concept of regression, often called as, “all else being equal”, “controlling for other variables”, or “Ceteris paribus”. The author explained this concept using “the circuit board analogy”.

Regression analysis is a method used by economists and data analysts to look at diffrent ways that can identify correlations in the data set.

Q3 What is a drawback of regression analysis. What type of questions can regression analysis not answer?

Hint: A correct answer must have a discussion on causality versus correlation.

A drawback of regression analysis is that it cannot prove causation it can only show a corrlation.

Q4 What role does the quality of schools play in academic performance of students.

Hint: See page 150.

There are many key factiors that play in to academic performance and quality of the schools also are a factor. The factors that can cause that are, class size, teachers’ education, computer-to-student ratio, gang problems, nonstudents loitering. If your area has thease issues then it has been proven to have a effect.

Q5 Continued from Q4. How could you control for the quality of schools in the study?

Hint: For this question, you may need additional information in addition to the assigned reading. You may Google search someting like “how does regression control for variables”.

I dont think its possible to control the quality of schools because many of the factors that have an effect on proformance happen out side of school so changing things in school wont make a diffrence.

Q6 The author says that regression is more art than science. What does he mean?

He means that therer is many diffrent and hidden factors that can all play a roll in an outcome much just like art.

Q7 What are major takeaways from the reading?

The major take aways from this reading are that there are many factors that play in regression. Regression Analysis can solve problems and make it clear for you to see what you want to look at.
