This is an example of...

• Reliability but Not Validity

• Validity but Not Reliability

• Neither Validity or Reliability

• Validity and Reliability

• Measures the consistency of the measurement taken under the study.

• Covers the the full range of the issue set for the study

• Measures the accuracy of the concept that it supposes to measure.

Whether a measure is actually measuring what it claims to be measuring - this refers to ...

• Reliability

• Validity

Participants completed a personality test. A week later, the researcher asked the participants to complete the test again and revealed consistent results. This shows that the test is:

• Valid

• Reliable

Which one of these won't help to improve validity

• Using appropriate equipment

• All variables controlled

• A method that tests the hypothesis

• Changing more than one thing in the experiment.

To ensure results are reliable the experiment should be

• Done once

• Repeated

• Done as exactly the same as the method outlines

• Repeated if necessary

Repetition _______________ the effect of outliers and allows them to be removed.

• increases

• minimises

• equals

• justifies

Evidence-based conclusions are

• Conclusions based on personal opinions
• Conclusions derived from anecdotal evidence
• Conclusions that ignore empirical data
• Conclusions drawn from systematic analysis of empirical data.
