What is the difference between IV and HV?

IV (independent variable) and HV (hypothesized variable) are terms used in scientific research. The independent variable is the variable that is being changed or manipulated in an experiment, while the hypothesized variable is a variable that a researcher believes may affect the outcome of the experiment but is unable to control or manipulate. The independent variable is generally used to determine the relationship between independent and dependent variables, while the hypothesized variable is used to explain why a particular relationship exists. In short, the main difference between IV and HV is that one is controlled by the researcher, while the other is not.
