Hint: Make sure to discuss study’s goal, subjects, and variables in the data.
The Early childhood Longitudinal Study that the U.S. Department undertook in the late 1990s. It was a design that included over twenty thousand students from the first grade to the fifth grade. The ECLS listed student’s academic performance and collected general information such as nationality and gender. Student interviews also involved the student’s parents and school administrators. The results of this project leave students with superb data that tell remarkable stories.
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 powerful analytical process that allows you to explore the correlation between two or more variables of curiosity. While there hold various varieties of regression analysis, by their gist people all examine the influence of one or more independent variables on a dependent variable.
Hint: A correct answer must have a discussion on causality versus correlation.
The drawback of regression analysis is that it can show a similarity between the subjects but it can’t determine the cause. Regression analysis cant determine questions that deal with proving a cause. For example, it can’t answer a question like: does writing a number of essays in your life leading up to your child performing better in writing? It simply won’t answer this because it can’t prove it because the child might not put his time into learning grammar and stuff.
Hint: See page 150.
Students who attend a better quality of schooling does, in fact, play a huge role in students’ academic performance. Students who go to private schools tend to get into better colleges. Public schools and private schools often send kids to college, while trade schools often give students jobs right out of highschool.
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”.
To control the quality of schools, I would have private school teachers host meetings and give valuable tips to teach their kids better. Like what they do that’s different from each other. I would mainly focus on and evaluate how students learn. As everyone learns differently, I would try to give different opportunities for students that learn. After evaluating, I would separate people into a group that has the same learning techniques to work and collaborate together.
One major takeaway from the reading was learning about regression analysis. Trying to figure out what it is and how it is used in the real world was fun and interesting. Not only did I learn about regression analysis but I learned about the ECLS project. It was cool to see how it helped over 20,000 students. I was very impressed to learn how students were performing in classes
