Body mass index (BMI) is one measure of body size commonly used in research.
It is calculated as or ∙ 703. From reported
weight and height in the class survey dataset, calculate each respondent’s BMI (note: BMI should be recorded as missing (.) if either height or weight is missing, and respondents with missing BMI should be excluded from this analysis). [You may wish to calculate this in Excel and then import again.]
a. WhatproportionofrespondentshadBMI<25?
b. What proportion had BMI of at least 25 but less than 30?
c. What proportion had BMI of 30 or greater?
I have already calculated the BMI through excel but i can't wrap my head around which code i need to come up with the answers.
Thank you in advance
Define the BMI categories as a format and use proc freq to calculate the proportions.
