WGU D514 Test - Questions With Expert Solutions
Quantitative Data Correct Ans - "Static" Numeric and Verifiable
Data.
Qualitative Data Correct Ans - Observable, categorical and
subjective Data.
P Value Correct Ans - The probability of results of the
experiment being attributed to chance. Utilized to test the
hypothesis. Lower P value indicates results are impacted by
intervention.
Independent Variable Correct Ans - Has an affect on the
dependent variable "what you control"
(Exercise machine) to see if BP is lowered, patient is on BP meds
Dependent Variable Correct Ans - Variable that is going to
change as a result of intervention
Exercise machine to see if (BP is lowered), patient is on BP meds)
Confounding Variable Correct Ans - obscures effect of another
variable
Exercise machine to see if BP is lowered, patient is on (BP meds)
Ordinal Variable Correct Ans - a qualitative variable that
incorporates an ordered position, or ranking.
ex. income levels, levels of agreement, levels of satisfaction
Continuous Variable Correct Ans - A variable that can take any
value in a given range
, (AKA Interval variable)
Numerical/Quantitative
ex. 10 degree temperature change, equal points on a chart.
ex. credit score, GMAT score, Temperature
Dichotomous Variable Correct Ans - Binary variable, occurs in
only two possible states.
ex. Patient is diabetic or non diabetic
Cross Sectional Study Correct Ans - Analyses data from subset
at a specific time. Data that will be pulled is predetermined.
ex. HR pulling records into how many employees were injured last
week.
Time Series Study Correct Ans - Analyzing data taken at
predetermined points.
Made up of multiple cross sectional data pulls.
ex. Monthly patient experience scores pulled.
Focus Group Correct Ans - Demographically diverse group
pulled together into a guided discussion.
Case Study Correct Ans - an observation technique in which
one person is studied in depth in the hope of revealing universal
principles. Usually no interaction with study subject
