Variables and Operationalization
Psychology ⇒ Research Methods in Psychology
Variables and Operationalization starts at 10 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Variables and Operationalization.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 11
A researcher wants to study the effect of caffeine on reaction time. Suggest an operational definition for 'reaction time'.
A researcher wants to study the effect of sleep on memory. What is the independent variable in this study?
A researcher wants to study the relationship between exercise and mood. Suggest an operational definition for 'exercise'.
A study examines the effect of background music on test performance. What is the dependent variable?

A researcher defines 'aggression' as the number of times a child hits a toy in 10 minutes. Is this an operational definition? (Yes/No)

Fill in the blank: A variable that can take on any value within a range is called a __________ variable.
Fill in the blank: A variable that is kept constant in an experiment to prevent it from influencing the outcome is called a __________ variable.
Fill in the blank: A variable that is not of primary interest but could influence the results if not controlled is called a __________ variable.
Fill in the blank: In an experiment, the variable that is deliberately changed by the researcher is called the __________ variable.
A psychologist measures stress by counting the number of times a person fidgets during an interview. Is this an example of operationalization? (Yes/No)
A researcher defines 'aggression' as the number of times a child hits a toy in 10 minutes. Is this an operational definition? (Yes/No)
True or False: A confounding variable is a variable that influences both the independent and dependent variables, potentially distorting the results.
True or False: Control variables are variables that researchers try to keep the same across all groups in an experiment.
