The 20 questions
-
What is a main practical advantage of using correlational research?
- Controls all variables
- Proves cause-effect
- Uses existing data
- Eliminates bias
-
What is a major limitation of correlational research?
- Uncontrolled third variables
- Time-consuming procedures
- Difficulty measuring data
- High ethical risk
-
Why might a strong correlation between reading ability and vocabulary size be misleading?
- Reading causes vocabulary
- Vocabulary causes reading
- Variables are unmeasurable
- Schooling affects both
-
Why are correlations often more ethical than experiments when studying stress?
- No stress induced
- Participants are anonymous
- Stress is cured
- Results are guaranteed
-
Why are correlations useful preliminary tools for researchers?
- They eliminate hypotheses
- They guarantee funding
- They suggest relationships
- They establish causation
-
What is the main limitation of a correlation based on an unrepresentative sample?
- Low generalisability
- Subjective scoring
- Low internal validity
- High demand characteristics
-
What is an advantage of using existing school records for correlational research?
- Quick and cheap
- Highly experimental
- Standardises environments
- Establishes causation
-
Why does a correlation between screen time and attention span not prove screen time causes short attention?
- Direction is unknown
- Data is qualitative
- Sample size varies
- Variables are unmeasurable
-
Which research method should follow a correlation to establish cause and effect?
- A scatter diagram
- An experiment
- A questionnaire
- A case study
-
Why would a researcher use a correlation rather than an experiment to study trauma?
- Financial profit
- Faster publishing
- Simplified statistics
- Ethical reasons
-
What is the primary strength of conducting correlational research?
- Proves direct causation
- Controls extraneous variables
- Explains underlying mechanisms
- Identifies relationships
-
What can a correlational study establish between two variables?
- A relationship
- An effect
- A cause
- A difference
-
If height and salary are correlated, what conclusion can be drawn?
- Salary causes height
- Height limits salary
- Height causes salary
- They are linked
-
What is a main limitation of correlational research?
- Requires large samples
- Cannot show causation
- Cannot plot graphs
- Uses no numbers
-
Why are correlations useful when studying potentially harmful variables?
- Proves exact causation
- Avoids ethical issues
- Eliminates participant bias
- Manipulates the IV
-
Which term describes a variable that may explain a correlation between two other variables?
- A control condition
- A demand characteristic
- A third variable
- A dependent variable
-
How do data points appear on a scatter diagram for a perfect correlation?
- A circle pattern
- A straight line
- A random scatter
- A curved line
-
What unmeasured factor might explain an observed correlation between two variables?
- An independent variable
- A third variable
- A control group
- A demand characteristic
-
Unlike experimental research, what can correlational research never demonstrate?
- Cause and effect
- Linear relationships
- Statistical links
- Quantitative data
-
What term describes the uncertainty over which variable caused changes in the other?
- Investigator effect
- Direction of causality
- Order effect
- Demand characteristic
