16
Q

TRUE or FALSE
In an experiment, the researcher looks for the possible effect on the dependent variable that might be caused by changing the independent variable.

A

TRUE

17
Q

For instance, in a study examining the effects of a new study technique on exam performance, the technique would be the _______ variable (as it is being introduced or manipulated), while the exam scores would be the ______ variable (as they represent the outcome of interest that’s being measured).

A

independent ; dependent

18
Q

TRUE or FALSE
There can be more than one independent or dependent variable in a study.

A

TRUE

19
Q

In some studies, researchers may want to explore how multiple factors affect the outcome, so they include more than one ______ variable.

A

independent

20
Q

may measure multiple things to see how they are influenced, resulting in multiple _______ variables.

A

dependent

21
Q

related to independent and dependent variables involve treating participants fairly and protecting their rights.

A

Ethical considerations

22
Q

Researchers must ensure that participants provide informed consent and that their privacy and confidentiality are respected. Additionally, it is important to avoid manipulating independent variables in ways that could cause harm or discomfort to participants.

A

Ethical considerations

23
Q

Researchers should also consider the potential impact of their study on vulnerable populations and ensure that their methods are unbiased and free from discrimination.

A

Ethical considerations

24
Q

TRUE or FALSE
Ethical guidelines help ensure that research is conducted responsibly and with respect for the well-being of the participants involved.

A

TRUE

25
Q

consists of participants who do not receive any experimental treatment.

A

control group

26
Q

The control participants serve as a ______ group.

A

comparison

27
Q

The control group is matched as closely as possible to the _________ group, including age, gender, social class, ethnicity, etc.

A

experimental

28
Q

The difference between the control and experimental groups is that the control group is not exposed to the ________ variable, which is thought to be the cause of the behavior being investigated.

A

independent

29
Q

TRUE or FALSE
Researchers will compare the individuals in the control group to those in the experimental group to isolate the independent variable and examine its impact.

A

TRUE

30
Q

The ______ ______ is important because it serves as a baseline, enabling researchers to see what impact changes to the independent variable produce and strengthening researchers’ ability to draw conclusions from a study.

A

control group

31
Q

TRUE or FALSE
Without the presence of a control group, a researcher cannot determine whether a particular treatment truly has an effect on an experimental group.

A

TRUE

32
Q

Control groups are critical to the ________ as they help ensure the internal validity of a study.

A

scientific method

33
Q

consists of participants exposed to a particular
manipulation of the independent variable.

A

experimental group

34
Q

These are the participants who receive the treatment of interest.

A

experimental group

35
Q

TRUE or FALSE
Researchers will compare the responses of the experimental group to those of a control group to see if the independent variable impacted the participants.

A

TRUE

36
Q

TRUE or FALSE
An experiment must have at least one control group and one experimental group; however, a single experiment can include multiple experimental groups, which are all compared against the control group.

A

TRUE

37
Q

TRUE or FALSE
Having multiple experimental groups enables researchers to vary different levels of an experimental variable and compare the effects of these changes to the control group and among each other.

A

TRUE
