EXST 2201 Exam 2 Kendall Hunt Exercises
(The question and the answers are interchanged, such that the answer comes first then the
questions)
To make an important decision in life, we want to know what
type of information from statistics? (4.1)
Population
Population Information information.
Probabilistic
information.
Probability
information.
Sample
information.
Why does the population contain more information
than a sample? (4.1) The population has more data
The population has more
values than a sample.
data values than a sample
The population is the totality of the individuals of interest.
Populations are defined by the researcher, so they
have more information. The population is used to
get a sample.
Why does more data values contain more information? (4.1)
Using more data values in the statistics gives a better
idea of all the data values in the population.
Using more data values in
the statistics gives a better
Because calculations are more efficient with
idea of all the data values in
the population
more numbers. Because calculation error is
less for bigger numbers.
,The same reason as more words in a paragraph gives more
, Select all steps used in the process to do
statistical inference. (4.1) Infer.
Theorize, analyze, infer
Analyze.
Theorize.
What type of statistics is used to get sample
information? (4.1) Descriptive statistics
Descriptive statistics because
because they describe the sample.
they describe the sample
Descriptive statistics because they involve
mathematical calculations. Inferential statistics
because they infer the population values.
Inferential statistics because they are more important than
descriptive statistics.

Inferential statistics because they infer the
population values. Descriptive statistics
because they involve mathematical
calculations.
Inferential statistics because they are more important than
descriptive statistics.
Why is knowing the values of the population
mean important? (4.1) Because most research
Because it gives one value
papers and reports require the population mean.
that is in the middle of all the
data values
Because it is used so often in statistics and
interpretation of statistics.
, Because it gives one value that is one of all the data values.
Because it gives one value that is in the middle of all the data values.
Please select one answer in response to the statement: "We
can never know the true value of a population mean". (4.1)
False, because the sample average is the same value
True, because we can never see
as the population mean. True, because we can never
the entire population to do the
calculation
see the entire population to do the calculation.
False, because population data is just another column
of data that can be used in calculations.
True, because population values must be given to us.
