NURS 329 PRACTICE SOLUTION SET 2026
QUESTIONS WITH SOLUTIONS GRADED
A+
⩥ types of true experimental designs Answer: the pretest-posttest
control group design; the posttest-only control group design, Solomon
4-group, Factorial, Repeated measures
⩥ quasi-experimental design Answer: An experiment that does not
require random assignment to conditions, but can manipulate IV,
Tx/Control,
⩥ Types of Quasi-Experimental Designs Answer: nonequivalent pre-
test posttest design, nonequivalent posttest only
⩥ methods to enhance equivalence if no random assignment? Answer:
-appropriate inclusion/exclusion criteria
-matching
-statistical control (ANCOVA)
-stat comparison of demographic characteristics/pertinent variables to
determine if differences between groups exist at outset
⩥ non experimental design definition Answer: describe relationships
among variables of ONE group of subjects; random assignment NOT
APPLICABLE
, ⩥ Types of non-experimental research Answer: ex post
facto/retrospective
descriptive correlational
time series design
survey research
outcomes research
secondary analysis, meta analysis, epidemiological, historical research
⩥ nonparametric testing data level Answer: nominal/ordinal
⩥ chi square Answer: Non parametric test used when you have
nominal data; used to determine whether two distributions differ
significantly; tests hypothesis about proportion of cases falling into
various categories; computed by summing differences between
observed and expected frequencies:
⩥ chi square example Answer: is there a difference between males
and females and smoking behavior?
⩥ Mann-Whitney U test Answer: a nonparametric test used to
compare two independent samples on an ordinal-level outcome
variable that utilizes ranking (nonparametric t-test equivalence)
