Question

Straight A’s now, healthy later A study by Pamela Herd of the University of Wisconsin– Madison found a link between high school grades and health. Analyzing data from the Wisconsin Longitudinal Study, which has tracked the lives of thousands of Wisconsin high school graduates from the class of $1957$, Herd found that students with higher gradepoint averages were more likely to say they were in excellent or very good health in their early $60\mathrm{s}$. Explain how confounding makes it unreasonable to conclude that people will live healthier lives if they increase their GPA, based on this study

Short answer

Confounding makes it unreasonable to conclude that people will live healthier lives if they increase their GPA, based on this study because it depends on several other factors like parents, enviornment, etc.

Step-by-step solution

Given information

We are given a study by Pamela herd of university of Wisconsin - Madison on confounding between grades and health.

Simplify

Pamela Herd of the University discovered a correlation between high academic results and health in her research.
In this study, we will examine the impact of children's health on grades and test scores.
Because private schools have more resources than public schools, the type of university may be a hidden variable.
Furthermore, parents who send their kids to private schools are more likely to be wealthy, to be in good health, and to receive good grades in school.
They are also more clever, which means they have a higher score than others.
As a result, there is a risk of confounding between grades and health.
