Question

can u give me sample problems of correlation with data of 20 students pertaining to their grades and BMI?

Answer 1

Solution:

Sample problem:

The study objective is to determine whether academic performance in university students is correlated with BMI. Students from two consecutive academic years (Jan–May 2015 and Jan–May 2016) were given an optional class survey in May, as extra credit. Of the 452 students that completed the survey, 204 females and 75 males (N = 279; 73% female and 27% male) consented to participate in the study. The number of correct answers to problem-solving questions (PSQs) and the overall final grade for the class are to be compared to the calculated BMI using linear regression with a Pearson's R correlation and unpaired t-tests.
