What is Homogeneity reliability?
Give this one a try later!
, Within the test...
Different questions, same construct/ idea
It assesses the correlation between multiple items in a test that are
intended to measure the same construct.

Different questions, same construct/ idea
Asking multiple questions to gather data on one topic
Define Debriefing. What is its importance
Give this one a try later!
It is informing the subjects after the observation and allowing them the
opportunity to refuse to have their data included in the study.
Explain a test of relationship

, Explores the relationship btwn 2 or more variables
Determining the correlation, the degree of association (ranges from -1.0 to
+1.0)
4 types of validity

Face Validity Content Validity Criterion-Related Validity
Construct Validity
Define positive skew/ right skew
Give this one a try later!
The "tail" of the skew is pointing to the right/ pointing is the poistive
direction along the number scale (x axis)
Define criterion-related validity
Give this one a try later!
Indicates the degree of relationship between the subject's performance on
the measurement tool and the subject's actual behaviour.
, What is test-retest reliability?
Give this one a try later!
Same people, same test, DIFFERENT TIMES
Explain Split-half-reliability
Give this one a try later!
You randomly split a set of measures into two sets. After testing the entire
set on the respondents, you calculate the correlation between the two sets
of responses.
Alternative vs. Null Hypothesis
Give this one a try later!
Alternative: proves what the researcher wants to prove
Null: disproves what the researcher wanted to prove
Why would a researcher set the alpha level at 0.01
