HannaahB Posted August 4, 2019 Report Share Posted August 4, 2019 For my biology IA I am going to compare one's BMI value to the new Relative Fat Mass Index value to determine how inaccurate BMI is for each person (I will average the percent error at the end as well). However, I'm struggling to determine what my independent variable is. Would it be an individuals height, weight, and waist measurement (which sounds wrong because its technically more than one thing being changed) or the test used (BMI vs. RFM)? I think the dependent variable would be the calculated percent error. Reply Link to post Share on other sites More sharing options...
