Comparison groups

Ethical or Unethical: After discovering that subjects are experiencing adverse reactions to an intervention, researchers agree to discontinue the study.

Ethical

Experimental

This research study design involves random assignment to groups and manipulation of the independent variable. a. Quasi-experimental b. Experimental c. Correlational d. Quantitative

Experimental

All experiments must include a minimum of three group of subjects. True False

False

In a factorial design, only one group of subjects is required because they act as their own control. True False

False

In non-experimental designs researchers manipulate the IV to determine cause and effect relationships True False

False

Nonequivalent control group pretest-posttest design is best defined as an experimental design where two groups are measured before and after an intervention. True False

False

Researchers use correlations to determine if there are difference between two groups. True False

False

Quasi experimental designs include which of the following essential components? a. Randomization, control group, and manipulation of IV b. Randomization and control group c. Manipulation of the IV d. Randomization and manipulation of IV

Manipulation of the IV

Experimental and quasi-experimental designs are similar in what aspect of the design? a. Manipulation of the dependent variable b. Manipulation of the independent variable c. Generalization of the findings d. Manipulation of the coefficient

Manipulation of the independent variable

What is unique in the Solomon four-group design versus other experimental group designs? a. Both control groups are measured before and after the intervention, while both experimental groups are measured after the intervention. b. Both control groups and one experimental group are measured before and after the intervention, while the other experimental group is measured after the intervention. c. Both the control and experimental groups are measured before and after the intervention allowing for replication of the study findings. d. One experimental group and one control group are measured before and after the intervention, while the other experimental and control groups are measured only after the intervention.

One experimental group and one control group are measured before and after the intervention, while the other experimental and control groups are measured only after the intervention

In nursing studies, the intervention is conducted with the experimental group, while the control group receives what? a. The usual standard of care. b. The intervention being tested. c. A combination of the intervention and standard of care. d. No care or intervention is provided

Descriptive data are usually cross sectional and can be collected through surveys and questionnaires? True False

True

In a two-group pretest-posttest design, the subjects are randomly assigned to the experimental or control group and measured before and after the intervention. True False

True

Non- experimental designs can be used to develop and test theories. True False

True

Patients who are not in the intervention group must receive the usual standard of care. True False

True

The Solomon four group design is more effective at controlling for the treat of treating than is the two group pretest- posttest design? True False

True

The purpose of non experimental designs are to describe , explain and predict relationships. True False

True

Ethical or Unethical: A researcher assistant carefully explains in English, without using an interpreter the benefits and risks of being in a study to a woman who speaks only Spanish.

Unethical

Ethical or Unethical: A researcher tells a subject that he will not receive as high quality care if he withdraws from the study.

Unethical

A nonexperimental research design is best defined as: a. a research design with manipulation of the independent variable and random assignment. b. a research design with manipulation of the dependent variable and random assignment. c. a research design that lacks manipulation of the independent variable and random assignment. d. a research design that lacks manipulation of the independent variable with no random assignment
