Unit 2: Research Review

Method of intense study of just one individual:

• Naturalistic Observation

• Experimental Study

• Case Study

• Survey

In an experiment, the _________________ variable is tested by the researcher to observe its effect(s) on the _________________ variable.

• A.independent; dependent

• B.first; second

• C.dependent; independent

• D.research; results

This research method is a descriptive technique in which one individual or group is studied in depth in the hope of revealing universal principles

• Case Study
• Survey
• Observational
• Correlational
• Experiments

This is a method of research where an investigator manipulates one or more factors (independent variables) to observe the effect on some behavior or mental process (the dependent variable).

• Experiments
• Case Study
• Survey
• Observational
• Correlational

The advantage of this descriptive method of research is that it creates an immense amount of data to be gathered quickly and inexpensively.

• Survey
• Observational
• Correlational
• Experiments
• Case Study

Identify the type of relationship between weight and price.

• The price is never 0 on the graph

• As weight increases, price increases

• There is a negative linear correlation between weight and price

• The price gets high at the end of the graph

Cardinal rule of naturalistic observation:

• Setting up dependent and independent variables

• Research and find enough participants

• Not disturbing participants in the study

• Getting enough different age groups for study

An individual suffered a major traumatic brain injury after getting in a bad accident at work. If a psychologist wants to know the effects of the trauma, what method would be best?

• Naturalistic observation

• Case study

• Experimental research

• Survey

In experimental studies which group receives nothing? In other words, they do not get the variable that is under study.

• Experimental group

• Control group

This refers to the method of gaining enough participants that represent various backgrounds of people, allowing researchers to generalize results to the larger population:

• Full sampling

• Double-blind placebo experiment

• Random sampling

• Naturalistic study
