Question

the sample that is not exposed to the independent variable and is the standard that is used to determine if the dependent variable is affected by the independent variable in the predicted manner.
a) control
b) dependent variable
c) hypothesis
d) prediction

Explanation:

In experimental design, a control group (or control sample) is not exposed to the independent variable. It serves as a standard to compare with the group exposed to the independent variable, helping to determine if the dependent variable is affected by the independent variable as predicted. A dependent variable is what's being measured (affected), a hypothesis is a proposed explanation, and a prediction is a statement of what is expected to happen. So the correct term here is "control".

Answer:

a) control
