Question

Suppose I'm going to do a study to see if I can use the high school GPA of college students to predict their college GPA.

Please let me know What are the cases?

What would be an appropriate label?

Give four examples of variables I could use and state whether they are categorical or quantitative variables and also state possible values each variable can take:

Answer 1

The report builds on a various study and examines whether high school GPA is less predictive for certain groups of students, such as students coming from different parts of the state or recent high school graduates than older students. regression analysis can be used to assess the extent to which high school GPA and test scores predict college grades. High school GPA explained 10-19 % variance in course grades for urban students, while test scores explained 1-4% variance. Similarly, high school GPA explained 8-22 % variance in course grades for rural students, while test scores explain 0-4 % variance in course grades. High school GPA can also predict the college course performance for students who directly entered college from high school compared to those who has delayed entry In a study it was proved GPA was a better predictor of college performance than scores on the SAT, ACT or similar examinations. Obviously students who exhibit better academic preparation in high school are more likely to complete college easily. But academic preparation can also mean different things. There are two ways to measure a student's academic performance (a)scores on standardized tests such as the SAT (b) grades in high school coursework. The SAT and similar tests exist to identify the differences in high schools grade students. Some teachers does not give students high marks despite excellent academic performance, this is called grade inflation. some high schools may run more tough courses than others. As a result, an A+ GPA at one school might be equivalent to a B+ at another,
