Question

1. taylor wanted to see if eating apples would help her do better on her classwork. the first day, she didnt eat any apples. on day 2, she ate one apple, on day 3, she ate 2 apples, and on day 4, she ate 3 apples. each day, she recorded the grades she got on her science work.

a. independent variable (iv):
b. dependent variable (dv):
c. control:

Explanation:

Part a: Independent Variable (IV)

The independent variable is the factor that is manipulated or changed in an experiment to observe its effect on another variable. In Taylor's experiment, she is changing the number of apples she eats each day. So the independent variable is the number of apples eaten per day.

The dependent variable is the factor that is being measured or observed and is expected to change in response to the independent variable. Here, Taylor is recording her science grades to see how they are affected by the number of apples she eats. So the dependent variable is her science grades.

A control in an experiment is a group or condition that is used as a standard of comparison. In this case, the day when Taylor didn't eat any apples (day 1) serves as the control because it provides a baseline to compare the grades from the days when she ate apples.

Answer:

Number of apples eaten per day

Part b: Dependent Variable (DV)
