Research Basics
100

This type of quantitative research describes and interprets current conditions without manipulating variables.

Descriptive Research

100

This quality of research means it is based on actual evidence and not personal opinions.

Objectivity

100

This is the variable that the researcher manipulates in an experiment.

Independent Variable

100

Variables that can take on any value within a range are called this.

Continuous Variable

100

The first step in conducting research is identifying this.

Research Problem

200

This type tests cause-and-effect relationships by manipulating one variable and controlling others.

Experimental Research

200

This characteristic ensures that the results are consistent when repeated under similar conditions.

Reliability

200

This is the variable that is measured in an experiment.

Dependent Variable
200

This type of variable is based on ranking or order but without consistent differences between

Ordinal

200

A possible answer to a research problem, stated in a testable form.

Hypothesis

300

This method studies the relationship between two or more variables without establishing causation.

Correlational Research

300

This trait ensures that research truly measures what it intends to measure.

Validity

300

These variables can influence results but are not the main focus of the study.

Extraneous Variable

300

These variables have equal intervals between values but no true zero point.

Interval Variable

300

The process of reviewing existing studies to understand what has been done before.

Literature review

400

This research follows subjects over a period of time to observe changes and developments.

Longitudinal

400

This means research findings can be generalized to larger populations.

Generalizability

400

These variables can confuse results because they change alongside the independent variable.

Confounding Variable


400

These variables have equal intervals and a true zero point, such as weight or height.

Ratio

400

The plan that describes how research will be conducted, including methods and tools.

Research design

500
A type of research that examines the cause and effect relationships

Causal Comparative/ Quasi-experimental

500

This characteristic ensures that research is free from bias and reflects true findings.

Objective/ Neutral

500

These variables categorize subjects without a natural order, such as gender or blood type.

Nominal Variable

500

Variables that take on only whole numbers or distinct values are called this

Discreet Variable

500

An illustration of the relationship between variables
