Understanding Quantitative Research

Which of the following is NOT a type of quantitative research design mentioned in the video?

• Correlational

• Qualitative

• Descriptive

• Experimental

What is the primary focus of descriptive research?

• To establish cause-effect relationships

• To describe the status of a variable or phenomenon

• To manipulate variables

• To measure the correlation between variables

In descriptive research, when is a hypothesis typically formed?

• No hypothesis is formed

• During data collection

• After data collection

• Before data collection

What is a key characteristic of correlational research?

• A hypothesis is formed before data collection

• It establishes cause-effect relationships

• Variables are measured but not manipulated

• Variables are manipulated

What does a positive correlation indicate?

• The variables are manipulated

• As one variable increases, the other also increases

• There is no relationship between the variables

• As one variable increases, the other decreases

What is the main goal of experimental research?

• To describe phenomena

• To measure correlations

• To establish cause-effect relationships

• To compare groups without manipulation

In experimental research, what is typically manipulated?

• Independent variable

• Control variable

• Random variable

• Dependent variable

How does quasi-experimental research differ from true experimental research?

• It lacks random assignment of participants

• It always includes a control group

• It measures correlation instead of causation

• It does not manipulate any variables

What does the prefix 'quasi' in quasi-experimental research mean?

• True

• Opposite

• False

• Resembling

Which of the following is a limitation of quasi-experimental research?

• It cannot measure correlations

• It lacks random assignment and/or control groups

• It cannot establish any relationships

• It cannot describe phenomena
