Hypothesis: If the temperature is higher, then performance will be decreased because the increased temperature may lead to dehydration and therefore lowered ability.
How does temperature affect a football players performance?
When playing football within hot temperatures, a player’s total distance and high-intensity activity will decrease markedly, though accompanying elevations in average heart rate and blood lactate are not always seen, when compared to performance within a temperate environment (Mohr et al., 2012).
How does temperature affect a football players performance independent variable?

When writing a hypothesis which variable is the IF?
A hypothesis states a presumed relationship between two variables in a way that can be tested with empirical data. It may take the form of a cause-effect statement, or an “if x,…then y” statement. The cause is called the independent variable; and the effect is called the dependent variable.
What is the control in an experiment?
Essentially, a control variable is what is kept the same throughout the experiment, and it is not of primary concern in the experimental outcome. Any change in a control variable in an experiment would invalidate the correlation of dependent variables (DV) to the independent variable (IV), thus skewing the results.
Is a Classroom noisier when the teacher leaves the room?
Is a classroom noisier when the teacher leaves the room? Teachers have rules about when to talk in the classroom. If they leave the classroom, the students feel free to break the rules and talk more, making the room nosier.
What effect does listening to music have on student test scores?
The result of the study showed that music with a higher intensity is more distracting and has a greater effect on task performance and concentration. The result helped formulate the Attention Drainage Effect theory, which is based on Kahneman’s (1973) capacity model of attention.
Do different types of music affect how well a person can do his/her homework?
Experiment #2 Question : Do different types of music affect how well a person can do his/her homework? Hypothesis : Music that does not have a strong beat makes concentrating on a homework assignment easier. Music with heavy beats makes concentration more difficult.
