Why does an investigator change the value of a variable parameter during an investigation?

Answer: Hi!

Usually you have two types of variables, the independents (parameters that you can change and modify, such as the time you left a potato in a hot oven) And dependent variables ( such as the temperature of said potato when you took it out of the oven).

The parameters in a investigation are independent variables, and you want to change them to see how the changes impact in the dependent variables, in order to describe these changes.

An investigator doesn't change the value of a  variable parameter because it changes by itself since a variable parameter is factors that change or vary throughout the experiment. Hope this answers the question. Have a nice day. Feel free to ask more questions.
