Variables

The video tutorial explores the concept of variables in psychology, emphasizing their importance in research and exams. It defines variables, discusses their types, and explains operationalization with examples. The tutorial also covers extraneous variables and demand characteristics, highlighting methods to control them in experiments. The conclusion reinforces the relevance of these concepts in psychology and provides exam tips.

Why are variables considered important in psychology?

• They are not relevant to students.

• They are fundamental to understanding psychological research.

• They are rarely mentioned in exams.

• They are only used in specific studies.

What is the role of an independent variable in an experiment?

• It is the outcome being measured.

• It is manipulated to observe its effect.

• It is not used in psychological experiments.

• It remains constant throughout the study.

How is operationalization used in psychological research?

• By avoiding the use of variables.

• By defining variables in measurable terms.

• By using general ideas without specifics.

• By ignoring abstract concepts.

What are extraneous variables?

• Factors that are irrelevant to the study.

• Variables that are always constant.

• Factors that can unintentionally affect the outcome.

• Variables that are intentionally manipulated.

Which method is used to control participant variables?

• Using random allocation and matched pairs design.

• Ignoring individual differences.

• Changing the environment frequently.

• Allowing participants to choose their tasks.

What are demand characteristics?

• Factors that have no impact on the study.

• Variables that are always controlled.

• Clues that lead participants to guess the study's purpose.

• Participants' natural behaviors.

How can researchers minimize the impact of demand characteristics?

• By revealing the study's purpose.

• By using double-blind trials.

• By allowing participants to discuss the study.

• By ignoring participants' behaviors.
