What is a hypothesis?

• A) A statement about the predicted relationship between two or more variables in a study.

• B) A detailed description of the methodology used in a study.

• C) A summary of the results obtained from a study.

• D) A review of the literature related to a study.

What must be provided to make variables under study testable?

• A) Hypothetical definitions

• B) Operational definitions

• C) Theoretical definitions

• D) Conceptual definitions

What do operational definitions describe?

• A) The theoretical background of the study

• B) The predicted outcomes of the study

• C) How the variables in a study are measured

• D) The literature review of the study

Why is random sampling important in most research designs?

• It increases the sample size

• It ensures the study is completed quickly

• It eliminates potential biases in the study

• It reduces the cost of the study

What does the method chosen for a study largely depend on?

• The available resources

• The nature of the question under study

• The time available for the study

• The number of researchers involved

What must researchers choose after selecting the research method?

• The hypothesis

• The data collection tools

• The participants for their study

• The research location

What type of statistics do researchers use to draw conclusions and decide whether their hypothesis has been supported?

• Descriptive statistics

• Inferential statistics

• Qualitative statistics

• Predictive statistics

What is the purpose of replicating studies in research?

• To increase the complexity of the research

• To further prove or potentially disprove previous research results

• To make the research more subjective

• To reduce the cost of research

What is an experiment in research?

• A) A method where researchers observe variables without interference.

• B) A method where researchers manipulate a variable under controlled conditions.

• C) A method where researchers only collect data from surveys.

• D) A method where researchers use historical data to predict future outcomes.

What is the purpose of an experiment?

• A) To observe natural occurrences without interference.

• B) To find out whether changes in one variable cause changes in another variable.

• C) To collect data from a large sample size.

• D) To analyze historical data trends.
