How do you assess convergent and discriminant validity?
Convergent and discriminant validity are essentially two sides of the same coin: convergent validity requires a positive correlation between different tests that measure the same thing; discriminant validity requires there to be no correlation between tests that measure different things.
How do you calculate discriminant validity?
To determine discriminant validity in PLS, some researchers use either way: compare square roots of AVE vs correlations between constructs whereby when the former (square roots of AVE) is higher than correlations between constructs indicating there is discriminant validity.
What is convergent validity and how we calculate?
Convergent validity states that tests having the same or similar constructs should be highly correlated. Two methods are often applied to test convergent validity. One is to correlate the scores between two assessment tools or tools’ sub-domains that are considered to measure the same construct.
Why are convergent and discriminant validity often evaluated together?
Why are convergent and discriminant validity often evaluated together? Both terms mean the same thing. Both involve collecting information from a lot of psychological measures of theoretical interest. Both require the use of scatterplots.
What is discriminant validity example?
A determination along the latter lines is referred to as discriminant validity (de Vet et al., 2011; Streiner et al., 2015). For example, a performance-based measure of walking should be positively correlated with self-reported ability to walk a block.
How do I do a validity analysis in SPSS?
Step by Step Test Validity questionnaire Using SPSS

- Turn on Variable View and define each column as shown below.
- After filling Variable View, you click Data View, and fill in the data tabulation of questioner.
- Click the Analyze menu, select Correlate, and select the bivariate.
What is an example of discriminant validity?
How do you measure concurrent validity in SPSS?
The concurrent validity of classifications is examined when you are interested in the extent to which classifications (master/non master) are correct. You determine this by correlating your classifications (x) with classifications or scores from a criterion measure (y).
What is convergent validity in statistics?
Convergent Validity is a sub-type of construct validity. Construct validity means that a test designed to measure a particular construct (i.e. intelligence) is actually measuring that construct. Convergent validity takes two measures that are supposed to be measuring the same construct and shows that they are related.
