Validity vs. Reliability
Research Design
Sampling
Research Process
100

the extent to which an experiment, test, or measure produces the same results on repeated trials.

What is Reliability

100

Research design in which the relationship among two or more variables is examined, but causality cannot be determined.  

What is correlational research?

100
Sampling technique that gathers samples, and allows everyone within the population an equal chance of being selected.
What is Probability Sampling
100
Overall strategy underlying the study, created only after a research question has been developed; serves as a visual model, as to how the question will be answered.
What is a Research Design
200

refers to the degree to which a study accurately reflects the content that the researcher is attempting to measure.

What is Validity

200

A single subject design that involves a baseline, manipulation and return to baseline. 

What is an ABA reversal design?

200
Ensure all participants are listed, then choose a random number of participants. (ex. everyone comes in and signs their names beside a number, the researcher then randomly picks 10 participants.
What is Simple Random Sampling
200
Type of research that is less structured, involves interviews, group discussions. Does not focus on statistical methods.
What is Qualitative Research
300

when a measure or test is repeated on the same subject at a future date.

What is Test-Retest?

300

Research design that manipulates a variable, but does not involve manipulation. 

What is quasi-experimental research? 

300

Subjects are selected because they are easily accessible. Easiest, cheapest, and less time consuming. (ex. classmates, family members, friends, etc.)

What is a convenience sample?

300
Type of Research that uses statistical methods to analyze numerical data.
What is Quantitative Research
400

Positive relationship between scores and a future behavior that is related to the construct assessed by the scale.

What is predictive validity? 

400

Research design in which the primary goal is to describe the variables, not examine relationships.

What is descriptive research?

400
When the researcher divides the entire population into different subgroups and randomly select the participants from the subgroup. (ex. Researcher chooses to study college students, he/she then divides the pop into 3 groups: athletes, non-traditional, and traditional. The researcher randomly selects the same amount from each group).
What is Stratified Sampling
400
1. Variable that the researcher wants to test. 2. Variable that the researcher believes will have a presumed effect.
What is 1. Independent Variable, 2. Dependent Variable.
500
extent to which 2 or more individuals agree; address the consistency of the implementation of a rating system.
What is Interrater Reliability.
500

Detailed investigation of single individual, group or organization.

What is a case study?

500
Used when it is either impossible or impractical to compile a list of subjects. (ex. the target pop is church members in the US, it is hard to compile a complete list of church members in the US). This type of sampling is also known as 2 stage sampling.
What is Cluster Sampling
500
A proposed explanation on the relationship of two or more variable, based on limited evidence.
