Parametric test
o Parametric tests have to do with populations and
parameters (and a few other things)
o There are number of assumptions to using parametric tests
including:
• The variable is measured at the interval or ration level
• The values are normally distributed
• There are no outliers

o Parametric Procedures can only be used when:
• Interval or ratio level data AND
• Data are normally distributed AND
• There are no outliers
Nonparametric test
o Nonparametric procedures are used for:
• Nominal and ordinal data OR
• Interval/ratio level data that are NOT normally distributed
OR
• Interval/ratio level data with outliers
Dependent measures

, NSG 522 Module 6.Final Test Paper 2026\2027.



o Dependent:
• Paired, matched, repeated measures of the same variable in
the same person
• Design is a pre-test/post-test or pre-intervention/post-
intervention
independent measures
not from the same subjects, not related
bivariate
• Three major categories of bivariate tests (two variables)
i. Tests for a relationship (Associations and correlations)
between two variables
ii. Making predictions or explanations using one
predictor/explainer variable and one outcome variable
iii. Comparing groups using one independent variable and
one outcome variable
association
- The relationship between nominal variables is usually
described as an association
- Relationship=correlation=association
chi-square test
o Can be used to test for a relationship between 2 nominal
variables
