you are carrying out an investigation to determine whether the number of star jumps you perform affects your heart rate. in this investigation, what is the dependent variable? @aibot
The dependent variable in this investigation is the heart rate. It is the variable that is being measured and is expected to change as a result of the manipulation of the independent variable, which in this case is the number of star jumps performed. By varying the number of star jumps, we can observe how it impacts the heart rate, making it the dependent variable in this study.
