How to know whether a methodological technique is quantitative or qualitative? How do you classify NASA TLX, ANOVA, Matched Pair T-Test, Self-Efficacy Scale, and System Usability Scale?
Are these types of data analysis considered quantitative or qualitative?
Please answer whether each is quantitative or qualitative.
Below are a few webpages about these forms of data analysis.

NASA TLX (Wikipedia),

ANOVA (Wikipedia),

Matched Pair t-Test  (Wikipedia),

The General Self-Efficacy Scale (GSE),

System Usability Scale (Usability.gov).


I believe that the NASA TLX, Self-Efficacy Scale, and System Usability Scale are qualitative. While ANOVA and the Matched Pair T-Test are both quantitative.
If I am wrong, please let me know what the correct answer is and why.
ANOVA and t-tests are statistical tests for significance and therefore quantitative.

The other mentioned items are scales (adding numbers to a certain choice) and therefore they can be considered as ordinal scales, and hence as quantitative as they are based on numbers. 

The NASA one can be administered by using a sliding scale which can be considered to be a continuous scale, allowing for parametric statistical testing. However, if divided in say 10 choices, it becomes an ordinal scale and non-parametric tests have to be used.
