Question

1. jimmy likes to work with his friend joe on 7th grade science class labs. however, he notices that he tends to get lower grades when he does work with joe, because he and joe like to talk about basketball and not science. hes decided to investigate if his science lab grades are higher when he works with joe or if theyre higher when he works with someone else. he has set goals to become a better student, so could you please help him write a hypothesis for his study?

hypothesis
if
independent variable
dependent variable
(then)
(because)
(independent variable)
(dependent variable)

Explanation:

Step1: Identify the variables

The factor Jimmy can control (whom he works with) is the independent variable. The outcome he is measuring (science lab grades) is the dependent variable.

Step2: Formulate the hypothesis

A hypothesis is an if - then statement. Based on the situation, the hypothesis relates the independent and dependent variables.

Answer:

• Independent variable: Whether Jimmy works with Joe or someone else
• Dependent variable: Jimmy's science lab grades
• Hypothesis: If Jimmy works with someone other than Joe on 7th - grade science labs, then his science lab grades will be lower because he tends to get lower grades when he works with Joe.
