NURS 630, Statistics: Field, A: Chapter 1
exam with answers
Quantitative methods - ** VERIFIED ANSWERS **✔✔Inferring evidence
for a theory through measurement of variables that produce
numeric outcomes.
Qualitative Methods - ** VERIFIED ANSWERS **✔✔Extrapolating
evidence for a theory from what people say or write.
Pilot FIsh - ** VERIFIED ANSWERS **✔✔(Naucrates ductor) - a
carnivorous fish in the Caragidae family known for congregating
around larger more impressive beings (e.g., sharks) and feeding
parasitically from their bodies.
Variables - ** VERIFIED ANSWERS **✔✔Anything that can be measured
and can differ across entities or across time.
Theory - ** VERIFIED ANSWERS **✔✔A hypothesized general principle
or set of principles that explain known findings about a topic and
from which new hypothesis can be generated.
Hypothesis - ** VERIFIED ANSWERS **✔✔A prediction about the state
of the world.
Falsification - ** VERIFIED ANSWERS **✔✔The act of disproving a
hypothesis or theory.
Independent Variable - ** VERIFIED ANSWERS **✔✔Another name for a
predictor variable. This name is usually associated with
experimental methodology, and is used because it is the variable
, that is manipulated by the experimenter and so its value does not
depend on any other variables.
Dependent Variable - ** VERIFIED ANSWERS **✔✔Another name for
outcome variable. This name is usually associated with experimental
methodology, and is used because it is the variable that is not
manipulated by the experimenter and so its value depends on the
variable that have been manipulated.
Predictor Variable - ** VERIFIED ANSWERS **✔✔A variable that is used
to try to predict values of another variable known as an outcome
variable.
Outcome Variable - ** VERIFIED ANSWERS **✔✔A variable whose value
we are trying to predict from one or more predictor variables.
Level of Measurement - ** VERIFIED ANSWERS **✔✔The relationship
between what is being measured and the numbers obtained on a
scale.
Categorical Variable - ** VERIFIED ANSWERS **✔✔Entities are divided
into two distinct categories. (i.e., student at University of Sussex vs
Harvard).
Binary Variable - ** VERIFIED ANSWERS **✔✔There are only two
categories (e.g., dead or alive), mutually exclusive.
Nominal Variable - ** VERIFIED ANSWERS **✔✔Nomine (name) -
Numbers merely represent names. There are more than two
categories (e.g., whether someone is an omnivore, vegetarian,
vegan or fruitarian).
Ordinal Variable - ** VERIFIED ANSWERS **✔✔The same as nominal
variable, but the categories have a logical order (e.g., whether
