Research method: experiment quiz

What is an operational definition?

• A summary of a study's findings

• A clear description of how a variable will be measured

• A method of participant selection

• A theoretical explanation of a phenomenon

Why is it important to control variables in an experiment?

• • To increase the complexity of the study

• • To ensure that any changes in the dependent variable are due to the independent variable

• • To simplify the data analysis process

• • To eliminate the need for a hypothesis

What is random sampling?

• Selecting participants based on convenience

• Choosing participants from a larger population at random

• Asking volunteers to participate

• Selecting specific individuals based on characteristics

What is a potential disadvantage of opportunity sampling?

• It is time-consuming

• It may lead to a biased sample

• It is too complex to implement

• It ensures diversity

What is the purpose of a control condition in an experiment?

• To introduce an independent variable

• To provide a comparison to the experimental condition

• To manipulate variables

• To increase the sample size

In an independent measures design, how are participants assigned?

• Each participant experiences all conditions

• Different participants are assigned to each condition

• Participants are matched based on specific traits

• Participants choose their own conditions

What is a demand characteristic?

• A bias that occurs when participants alter their behavior

• A variable that influences results

• An ethical concern in research

• A type of sampling method

What is the order effect?

• Changes in performance due to the sequence of tasks

• Differences between participants' backgrounds

• Variability in data due to sampling error

• Random differences in treatment

Which method can be used to control for order effects?

• Random sampling

• Counterbalancing

• Volunteer sampling

• Pilot study

What is a pilot study?

• A large-scale trial of the main study

• A small preliminary study to test feasibility

• A comparison between two different studies

• A study that lacks ethical guidelines
