CORRELATIONAL RESEARCH EXTRANEOUS VARIABLE DESIGN This is a variable that has no relationship - Relationships are sought to with the independent or dependent variable be interpreted. but can affect the outcome of the study. - Studies only the data, Extraneous variables can lead to erroneous relationships, and conclusions and can be controlled through distributor of variables. random assignment or statistical techniques.

TYPES OF RESEARCH QUESTIONS In Research, Variables refer to characteristics or DESCRIPTIVE RESEARCH QUESTION attributes that can be measured, manipulated, or - Seeks to describe phenomena or controlled. characteristics. Note: Manipulation of variables depend on - “What is...” which type of research design is being used. - Typically used in Survey / Descriptive Research.

It should be brief, direct, and give an DIFFERENCE RESEARCH QUESTION overview of what the study will be about. - Seeks to make comparisons between or within groups of interest. - Often associated with experimental research. - Comparison with the basis of existing characteristics.
