When they say a variable is independent, it’s because it is not explained by the model but rather used as an input to explain something else. The model takes some input (the independent variable – could be whatever number you want) and based on that input, gives you some output (the dependent variable).
Use weight and calories eaten. Which of these would be the independent variable? Hint: which one would impact the other (but doesnt make sense if you flipped it)?
