Answer:
Explanation:
An independent variable is a variable in which does not rely on how other variables. It is usually cause in an experiment. From Sara Lilia experiment, we can identify the different music genres as her independent variable.
The dependent variable here is her ability to concentrate in her study. Here, we should know that the dependent variable is often the result of the effects of the independent variable.
There is no control in the experiment. In the controlled set up, we would have put all other know factors that would make concentrations easier into consideration. It could be the environment, the arrangement of the room and a particular time of the day. None of such was stated in the experiment.
The constant variable is the variable that was held fixed throughout the experimental procedure. Here the time of study was fixed at 5minutes. What would happen to concentration if this time was shorter or much more?
