hypothesis

  a student gets more sleep, they will get a higher test score.

A hypothesis is a testable prediction or statement about the relationship between variables in an experiment. It typically follows an “If… then…” structure, where the “If” part refers to the cause or independent variable, and the “then” part refers to the effect or dependent variable. In this case, the hypothesis is making a specific prediction: if a student gets more sleep, then their test score will improve. This statement can be tested through experimentation, where the amount of sleep is controlled and test scores are measured.
