Section Two - C985 questions
fully solved & updated(graded
A+)
Categorical variables - answer the value is the name or label. Types of
cancers (breast, skin, lung) are categorical variables
confounding variable - answer it obscures the effect of another variable,
the research may initially believe the variable will have an influence on
research, but findings show it does not.
- as a researcher, you may not be able to control its influence on the result
of the research, but you should have an awareness that it is impacting
your results and do not allow it to skew your data
continuous variable - answer interval variable - meaningful difference
between values. example = body temperature
databases - answer well-designed healthcare database captures data to
support the organizations analysis and comparison of safety, quality,
effectiveness, efficiency, timeliness, and efficacy of actual care and
services delivered to the patient over time
data warehouses - answer assimilate data rom multiple transaction
systems. Data warehouses can be used to distinguish larger trends in data
from multiple sources
Dichotomous variable - answer also called binary variable - occurs in one
of two possible states
- for example male or female. The patient has cancer or does not.
Disease registries - answer a hybrid between transaction systems and
warehouses, are designed for tracking explicitly-defined data at a case-
specific level
