A student is designing an experiment about the factors that affect math grades. Which statement best represents a possible hypothesis for this
experiment?
A. I think practicing math problems is the most important factor in a
student's math grade.
B. If students spend at least 1 hour per night studying math, then
they will get a grade of 85 or higher.
C. Students who study more get higher math grades.
D. Steve studied math for 1 hour every night and got a grade of 87.

B. If students spend at least 1 hour per night studying math, then

they will get a grade of 85 or higher.

Explanation:

A hypothesis is a pivotal part of any scientific experiment. It is a testable explanation or suggested solution to the given problem that led to the experiment. A hypothesis aims to give a predictive explanation to an outcome. A hypothesis must be testable via an experiment, whose outcome either proves or disproves it.

Hypothesis usually goes in an IF, THEN format i.e if (cause), then (effect) and it contains the relationship between the independent and dependent variable of the experiment. In this question regarding students designing an experiment to determine how certain factors affect math grade, the best possible hypothesis will be: B. If students spend at least 1 hour per night studying math, then

they will get a grade of 85 or higher.

According to the hypothesis which is an IF (cause), THEN (effect) format. This means that spending at least one hour per night (independent variable) will cause the students to have a math grade of 85 or higher (effect). It suggests a possible solution to the problem, which can of course be tested by conducting an experiment.
