Data Collection Procedures

What is the main purpose of an intervention in research?

• To summarize previous studies

• To bring about a desired change

• To eliminate all variables

• To avoid ethical issues

Which of the following should be included when describing an intervention?

• What it is, who it's for, how it works, where/when it happens

• Research budget and timeline only

• Literature review of past interventions

• Number of researchers involved

In an experimental study, the variable that is manipulated is called:

• Dependent variable

• Control variable

• Independent variable

• Confounding variable

Which of the following is an example of a dependent variable?

• Amount of fertilizer applied

• Temperature of the room

• Height of the plant

• Number of samples chosen

Why are controlled conditions important in experimental research?

• To increase the sample size

• To ensure only the independent variable affects the outcome

• To minimize research costs

• To make the experiment more difficult

A pilot test in data collection is conducted to:

• Replace the main study

• Test the instruments and identify issues before the main study

• Increase the population size

• Skip ethical approval

Which research strand commonly uses experimental designs?

• ABM

• HUMSS

• STEM

• Arts

In non-experimental research, variables are:

• Manipulated

• Controlled

• Observed and measured

• Eliminated

Which design is most commonly used in ABM and HUMSS research?

• Experimental

• Descriptive and correlational

• Quasi-experimental

• Longitudinal intervention

Identifying and operationalizing variables refers to:

• Defining variables and constructs

• Pilot testing instruments

• Choosing respondents randomly

• Eliminating errors in sampling
