Research Literacy Quick Check (High-level)
School of Education & Behavioral Studies
A lightweight quiz about research literacy and interpretation. Not professional certification.
1
Which is most likely to improve reliability in a questionnaire?
Changing questions each time
Using clear consistent items and scoring
Using only open-ended questions
Collecting fewer responses
2
Correlation means:
One variable causes the other
The variables move together, but causation is not confirmed
The study is biased
The sample is random
3
A confounding variable is:
A variable measured carefully
A hidden factor that may influence both variables
A type of random error
A way to prove causation
4
Random assignment primarily helps with:
Generalizing to the population
Reducing selection bias between groups
Increasing the sample size
Eliminating measurement error
5
A p-value below 0.05 typically suggests:
The effect is huge
The result is unlikely under the null hypothesis
The study is perfectly designed
The variables are uncorrelated
6
Which is an example of qualitative data?
Test score average
Reaction time in ms
Interview themes about classroom climate
Number of participants
7
Validity is about:
Consistency of results
Whether the measure captures what it intends to measure
Number of items
Whether results are statistically significant
8
A larger sample size generally:
Always proves causation
Reduces random error and increases statistical power
Guarantees no bias
Makes data less reliable
9
Which is the best first step when reading a study?
Skip methods
Check the research question and design
Only read the conclusion
Ignore limitations
10
A limitation section is important because it:
Makes the paper longer
Shows where interpretation should be cautious
Proves the results are wrong
Is required for all blogs
