Which term below refers to a study involving the manipulation of one or more variables to determine the effect on another variable?
Correct Answer
B. Experiment
Explanation
An experiment refers to a study involving the manipulation of one or more variables to determine the effect on another variable. In an experiment, researchers intentionally change certain variables (independent variables) to observe the impact on another variable (dependent variable). This allows them to establish cause-and-effect relationships and draw conclusions about the effect of the manipulated variables on the outcome variable.
2.
Which variable in an experiment is manipulated by the researcher?
Correct Answer
D. Independent variable
Explanation
The independent variable is the variable that is manipulated by the researcher in an experiment. It is the variable that the researcher intentionally changes or controls in order to observe its effect on the dependent variable. The dependent variable, on the other hand, is the variable that is measured or observed to determine the effect of the independent variable.
3.
Which variable in an experiment is the variable expected to be affected by the manipulation?
Correct Answer
A. Dependent variable
Explanation
The dependent variable is the variable in an experiment that is expected to be affected by the manipulation. It is the outcome or response variable that is measured or observed to determine the effect of the independent variable. In other words, changes in the independent variable are believed to cause changes in the dependent variable.
4.
All of the following are terms used to refer to an independent variable except _____.
Correct Answer
C. Criterion
Explanation
The term "criterion" does not refer to an independent variable. In research, an independent variable is the variable that is manipulated or controlled by the researcher. It is the variable that is believed to have an effect on the dependent variable. "Predictor" and "explanatory" are terms that are commonly used to refer to an independent variable, as they imply a cause-and-effect relationship. However, "criterion" refers to a standard or measure used to evaluate or judge something, and it is typically used to refer to the dependent variable in research.

B. Control group
Explanation
A control group is used in an experiment to serve as a comparison to the experimental group. It allows researchers to assess the existence and potency of any manipulation or intervention being tested. By comparing the results of the control group to the experimental group, researchers can determine whether any observed effects are due to the intervention or simply due to chance. The control group provides a baseline against which the effects of the manipulation can be evaluated.
14.
When an experiment is conducted in actual environmental conditions, it is called a(n) _____ experiment.
Correct Answer
C. Field
Explanation
When an experiment is conducted in actual environmental conditions, it is called a field experiment. This type of experiment takes place in real-world settings, such as a natural environment or a specific location, rather than in a controlled laboratory setting. Field experiments allow researchers to observe and measure behavior and outcomes in a more realistic and authentic context, providing insights that may not be possible to obtain in a laboratory setting.
15.
Which source of evidence to support experimental results is most threatened by the use of a field experiment?
Correct Answer
C. Control of contamination from extraneous variables
Explanation
A field experiment involves conducting an experiment in a real-world setting, which makes it difficult to control or eliminate extraneous variables that could influence the results. Contamination from extraneous variables refers to the presence of factors other than the independent variable that may impact the dependent variable. Since field experiments are conducted in natural settings, it is challenging to control or minimize the influence of these extraneous variables. Therefore, the control of contamination from extraneous variables is most threatened by the use of a field experiment.

This step is crucial in designing a well-structured and meaningful experiment.
24.
When participants do not know if they are being exposed to the experimental treatment, they are said to be _____.
Correct Answer
A. Blind
Explanation
When participants do not know if they are being exposed to the experimental treatment, they are said to be blind. This term refers to the concept of blinding in research studies, where participants are kept unaware of whether they are receiving the actual treatment or a placebo. Blinding helps to eliminate bias and ensures that the results of the study are not influenced by participants' expectations or beliefs.
25.
When it is not possible to randomly assign participants to groups, _____ should be used.
Correct Answer
B. Matching
Explanation
When it is not possible to randomly assign participants to groups, matching should be used. Matching involves selecting participants for different groups based on specific characteristics that are relevant to the study. This helps to create comparable groups and reduce the influence of confounding variables. By matching participants on key variables, researchers can ensure that any differences observed between groups are more likely to be due to the treatment or intervention being studied, rather than other factors. Matching is especially useful in situations where random assignment is not feasible or ethical.
26.
Measurement in research consists of assigning numbers to _____ in compliance with a set of rules.
