Answers (100% Correct Answers)
statistics Answer: Consists of a body of methods of collecting and
analyzing data.
quantitative Answer: represents the amount or quantity of something,
it can be continuous or discrete
qualitative (categorical) Answer: data that results from descriptions

hypothetical population Answer: 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 Answer: 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 course deals with this kind of statistics.
inferential statistics Answer: includes methods like point estimation,
interval estimation and hypothesis testing which are all based on
probability theory.
parameter Answer: a determining or characteristic element; a factor
that shapes the total outcome; a limit, boundary
