Hint: Make sure to discuss study’s goal, subjects, and variables in the data.
The Early childhood Longitudinal Study is that the U.S. Department undertook in the late 1990s, it was a design that included twenty thousand students from the first to the fifth grade. The ECLS listed the students academic performance and collected general information such as nationality and gender. Student interviews also involved the students parents and school administrators. The results of this project left students with superb data that told 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 people to explore the correlation between two or more variables of curiosity. While they hold various varieties of regression analysis, by their gist people can 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 negative part 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 your child practicing a sport every day really make them better? it’s logistics won’t answer that.
Hint: See page 150.
Students who attend a better quality of schooling does play a huge role in students’ academic performance. Students who go to private schools do 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 most private school teachers host meetings and give valuable tips to teach their kids better. I would mostly 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 and trying to figure out what it is and how it would operate in the real world was interesting. Not only did I learn about regression analysis but I learned about the ECLS project, It was nice to learn how it helped over 20,000 students, I was very impressed to learn how students were performing in classes overall.
Hint: Use message, echo and results in the chunk options. Refer to the RMarkdown Reference Guide.
