A control group is_______ . a. a set of individuals that have a certain characteristic or receive a certain treatment b. the standard against which an experimental group is compared c. the experiment that gives conclusive results
a) Does the data support your hypothesis?
b) How could you improve this experiment? Consider the other factors you could have / should have controlled in this experiment.
The purpose of the constant is to:
a. allow for adjustment of the control
b. eliminate other potential factors/variables in the experiment
c. allow for the dependent variable to show the necessary outcome
d. help prove the hypothesis correct

- Ideally, an experimental group differs from a control group (a) only with respect to the hypothesis being tested (b) because its subjects are more reliable (c) in that it is less subject to bias (d) in that it is less vulnerable to sampling error (e) only with respect to the variable being studiedarrow_forwardWhy is it important to always use a large sample size in an experiment? A. To make sure that spontaneous generation is taking place B. To make sure that there are not two variables being tested C. Make sure the data is qualitative D.
