data.
quantitative Ans: represents the amount or quantity of something, it can

be continuous or discrete
qualitative (categorical) Ans: data that results from descriptions
Guru01 - Stuvia
ex) blood type of a person, marital status, religious affiliation
population Ans: the collection of all individuals or items under
consideration in a statistical study
sample Ans: that part of a population from which information is
collected
finite population Ans: In many cases the population under consideration
is one which could be physically listed.
ex) The students at UNCW
the books in a library
, For Expert help and assignment handling,
2
hypothetical population Ans: Also in many cases the population is much
more abstract and may arise from the phenomenon under
consideration.
ex) a factory producing light bulbs. If the factory keeps using the same
equipment, raw materials and methods of production also in future then
the bulbs that will be produced in factory constitute a hypothetical
population. That is, sample of light bulbs taken from current production
line can be used to make inference about qualities of light bulbs
produced in future.

descriptive statistics Ans: includes the construction of graphs, charts,
and tables, and the calculation of various descriptive measures such as
measures of variation, and percentiles. In fact, the most part of this
Guru01 - Stuvia
course deals with this kind of statistics.
inferential statistics Ans: includes methods like point estimation, interval
estimation and hypothesis testing which are all based on probability
theory.
parameter Ans: a determining or characteristic element; a factor that
shapes the total outcome; a limit, boundary
discrete variables Ans: Some variables, such as the numbers of children
in family, the numbers of car accidents on the certain road on different
days, or the number of students taking basics of statistics course are the
results of counting and thus these are __________. Typically, a ___________
is a variable whose possible values are some or all of the ordinary
counting numbers like 0,1,2,3,.... As a definition, we can say that a
variable is ______ if it has only a countable number of distinct possible
values. That is, a variable is ______ if it can assume only a finite number of
values as there are integers.
