100
An approach to psychology that treats it as one of the natural sciences, and therefore assumes that it is susceptible to the experimental method.
What is Experimental Psychology
100
is concerned with the selection of a subset of individuals from within a statistical population to estimate characteristics of the whole population
What is sampling?
100
Explores or tests relations between variables
What is correlational design/study?
100

The null hypothesis suggests that any observed difference is due to.

What is random error?

200

The the two primary methodologies used in scientific research.

What are qualitative and quantitative methodologies?

200
A research design in which every unit in the population has a chance of being selected in the sample
What is probability sampling?
200
Studies participants in their natural setting
What is field research design?
200
An error committed when the research falsely concludes that there was a treatment effect.

Type 1

300

This type of research design has more than 1 independent variable.

What is a factorial design?

300
A research design in which a given size, all such subsets of the frame are given an equal probability of being selected.
What is simple random sampling?
300
Directly establishes cause-effect nature of relationship between variables
What is experimental psychology designs?
300

The type of error committed when the research falsely concludes that there was not a treatment effect.

What is Type II

400

Variables measured on/at this scale of measurement have equal intervals and an absolute zero point that indicates the absence of the variable being measured.

What is the ratio (level)?

400
This research method relies on arranging the study population according to some ordering scheme and then selecting elements at regular intervals through that ordered list.
What is systematic sampling?
400
A small group of representative people who are questioned about their opinions as part of a research project.
What is a focus group?
400

Which parametric inferential test is appropriate to test differences between the means of two independent groups.

What is an independent samples t-test

500

The type of validity surrounding the extent to which findings may be generalized.

What is external validity?

500
Where the population embraces a number of distinct categories, the frame can be organized by these categories into separate "strata."
What is Stratified sampling?
500
Research for asking questions: conducting research during which somebody is asked questions
What is an interview?
500

What type of analysis is considered predictive.

What is Regression Analysis?
