Instruments Questions and Answers with 100%
Complete Solutions UPDATED!!!
Research Instrument - ANSWER - Refers to the device being
used to measure
Types of Instruments - ANSWER - Researcher-completed (e.g.
performance checklist, fMRI, interview)
- Subject-completed (e.g. questionnaire, survey)
Usability - ANSWER - How easy to use and efficient the
instrument is
- How long will it take to administer? Are the directions clear?
Validity - ANSWER - Making sure the instrument is measuring
what it claims to measure
- Problem: Measured in degrees because it can never be 100%
validity
- Validation involves assessing the accuracy of instrument by
collecting and analyzing data

Internal Validity - ANSWER - Extent to which you are able to say
that there are no other variables except the one you're studying
caused the result
- No extraneous variables
- DV due to IV and nothing else
External Validity - ANSWER - Extent to which results of s study
can be generalized to the world
Face Validity - ANSWER - Simply whether the test appears to
measure what it clams to measure
- Used for instruments like the Likert Scale
Content Validity - ANSWER - Same as FV but given to experts to
measure if it covers the full domain
- Used for instruments like the Thurstone Scale
Construct Validity - ANSWER - Construct: Collection of behaviors
associated in to create an image/idea invented for a research
purpose
