normal
Are the intervals equal in normal data?
yes equal intervals between values
What type of data allows for certain kinds of statistical tests, called ‘parametric’ statistics
Normal
______statistical tests have more ‘power’ (or ability) to detect relationships and/or differences
parametric
What type of data allows for the use of nonparametric statistics?
Nominal & Ordinal
______statistical tests have less ‘power’ to detect relationships and/or differences

What’s the difference between nominal and ordinal data?
Nominal level data can only be classified, while ordinal level data can be classified and ordered.
Are Likert scales ordinal/scale/nominal data?
Ordinal
Why are likert scales ordinal data?
because the items have clear rank order, but don’t have an even distribution.
