D514 Test Study Material with Complete
Solutions
Quantitative Data
"Static" Numeric and Verifiable Data.
Qualitative Data
Observable, categorical and subjective Data.
P Value
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
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
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
obscures effect of another variable
Exercise machine to see if BP is lowered, patient is on (BP meds)
Ordinal Variable
,a qualitative variable that incorporates an ordered position, or ranking.
ex. income levels, levels of agreement, levels of satisfaction
Continuous Variable
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
Binary variable, occurs in only two possible states.
ex. Patient is diabetic or non diabetic
Cross Sectional Study
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
Analyzing data taken at predetermined points.
Made up of multiple cross sectional data pulls.
, ex. Monthly patient experience scores pulled.
Focus Group
Demographically diverse group pulled together into a guided discussion.
Case Study
an observation technique in which one person is studied in depth in the hope of revealing
universal principles. Usually no interaction with study subject
ex. How health system because one of the first integrated health delivery models
Cohort Study
Following a subset of a population over a time. Usually answers a healthcare question
ex. 20 year study on how eating habits influence genetic inheritance
Longitudinal study
study that occurs dover a long period or time
Literature Review
Learning and reviewing documents for learnings sake.
Meta Analysis
Literature review but you also take action on what you learned
ex. learning about proper lifting techniques and then implementing a course to train others.
Factor Analysis
