Question

claim 2. eating breakfast increases performance in school (5pts)
hypothesis: if __________________, then __________________

independent variable:		control(s):
dependent variable:
experimental group

Explanation:

To formulate the hypothesis, we base it on the claim that eating breakfast increases school performance. The independent variable is what we manipulate (eating breakfast), the dependent variable is what we measure (school performance), controls are factors kept constant (like same school, grade, study materials), and the experimental group is those who eat breakfast.

Hypothesis:

If a student eats breakfast, then their performance in school will increase.

Independent Variable:

Whether a student eats breakfast (this is the factor we change to see its effect).

Dependent Variable:

Student performance in school (this is the factor we measure to see the effect of the independent variable).

Control(s):

• Same school environment (e.g., same school, same grade level).
• Same study materials and teaching methods.
• Same time of day for testing/assessing performance.

Experimental Group:

The group of students who are given breakfast (or instructed to eat breakfast) before attending school.

Answer:
