EXAM STUDY QUESTIONS AND 100%
CORRECT ANSWERS!!

inspecting the data.
false; it should be BEFORE
True or false: Published statistics tend to be optimistic.
true
What is quantitative variable
have a numerical value associated.
Quantitative variable types
Continuous -> infinite number
Discrete
What is qualitative variable?
without a numerical value associated,
refer to a category or quality.
Qualitative variable type
Ordinal -> can be ranked
Nominal variable
What is Response or dependent variables?
rincipal variable of the
study, the outcome of the study
, What is the Explanatory or independent variables?
variables that have
an effect on the response variable, you watch what happens to the dependent variable
What is the classification of the variables according to their role
independent and dependent
Generally, age is consider as a
quantitative CONTINUOUS
What is a population?
It's the set of elements or individuals that meet the characteristics that are intended to study.
Normally the number of individuals in the population is represented by the letter ?
N
What is the target population?
set of individuals to whom the results are
intended to be inferred; generally very numerous and
not available to researchers
What is accessible population?
comes from the target population but with a smaller number of individuals, and therefore,
susceptible
to study.
What is study population?
comes from the accessible population and is the population from which the data are actually
collected.
In the accessible, what do we want to study?
objective
