NURS 329 FINAL EXAM QUESTIONS
AND 100% ACCURATE ANSWERS.
True experimental design - Answer -manipulation of IV
Tx and Control group
-Random Assignment to treatment and control group to optimize equivalence
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)
logistical regression - Answer tests relationships between multiple IVs and a NOMINAL DV: probability
of an event to occur
logistical regression example - Answer do weight, height, and gender predict an MI (yes/no)?
multiple regression - Answer to predict relationships: do multiple IVs predict a DV? (I/R level data)
multiple regression example - Answer do hours of sleep, hours of studying, age, and gender predict
scores on a research exam?
simple linear regression - Answer regression analysis involving one independent variable and one
dependent variable in which the relationship between the variables is approximated by a straight line
simple linear regression example - Answer do number of daily calories consumed predict weight in lbs?
parametric test level of measurement - Answer DV is at interval or ratio level
