multiple choice. choose the one alternative that best completes the statement or answers the
question.
1) the process of using data collected from a small group to reach conclusions about a
large group is called:
a) dcova framework.
b) descriptive statistics.
c) statistical inference.
d) operational definition.
ANS:>c)
the process described here is statistical inference, which uses sample data to make
generalizations or predictions about a larger population. it involves drawing conclusions
or making decisions based on data from a smaller group, known as a sample, to infer
characteristics about the larger population.
objective:
2) those methods involving the collection, presentation, and characterization of a set of
data in order to properly describe the various features of that set of data are called:
a) dcova framework.
b) statistical inference.
c) descriptive statistics.
d) operational definition.
ANS:>c)
descriptive statistics refers to methods for organizing, displaying, and summarizing data.
this includes tables, charts, and numerical measures that describe the main features of a
data set, such as mean, median, and mode, without making inferences or predictions.
, objective:
3) the collection and summarization of the socioeconomic and physical characteristics of
the employees of a particular firm is an example of:
a) inferential statistics.
b) dcova framework.
c) operational definition.
d) descriptive statistics.
ANS:>d)
this is an example of descriptive statistics because it involves the summarization and
description of data related to the characteristics of employees. no predictions or
inferences about a larger population are made in this case.
objective:
4) the estimation of the population average family expenditure on food based on the
sample average expenditure of 1,000 families is an example of:
a) inferential statistics.
b) dcova framework.
c) operational definition.
d) descriptive statistics.
ANS:>a)
this example involves inferential statistics because the average expenditure on food of a
sample is used to estimate the average expenditure for the entire population. it makes a
prediction or generalization based on sample data.
objective:
5) which of the following is not an element of descriptive statistical problems?
a) tables, graphs, or numerical summary tools.
b) an inference made about the population based on the sample.
