STUDY GUIDE LATEST UPDATED RATED A.
Is computed by summing all the data values and dividing the sum by the
number of items
Correct Answer -The mean of a sample is
The data set is a sample
Correct Answer -If the variance of a data set is correctly computed with the
formula using n − 1 in the denominator, which of the following is true?
Which of the following symbols represents the size of a population?
Correct Answer -N
negative
Correct Answer -The variance of a sample or a population cannot be
-1 and +1
Correct Answer -The correlation coefficient ranges from which two values
median
Correct Answer -The measure of central location most often reported for
annual income and property value data is the
squared value of the standard deviation
Correct Answer -The variance is equal to the
,.05
Correct Answer -The finite correction factor should be used in the
computation of σx̄ and σȳ when n/N is greater than
sample statistic
Correct Answer -The value of the ___________ is used to estimate the
value of the population parameter
the population is first divided into groups, and then random samples are
drawn from each group
Correct Answer -Stratified random sampling is a method of selecting a
sample in which
standard error of the proportion
Correct Answer -The standard deviation of p̄ is referred to as the
numerical characteristics of a population
Correct Answer -Parameters are
if the sample size n is large and the population is normal, then the
sampling distribution of the sample mean can be approximated by a
normal distribution.
Correct Answer -The central limit theorem states that
probability sampling method
Correct Answer -cluster sampling
probability sampling method
Correct Answer -stratified random sampling
, probability sampling method

nonprobability sampling method
Correct Answer -judgement sampling
The entity on which data are collected.
Correct Answer -element
the collection of all the elements of interest.
Correct Answer -population
a subset of the population.
Correct Answer -sample
A characteristic of interest for the elements.
Correct Answer -Variable
The set of measurements obtained for a particular element.
Correct Answer -Observations
Data in the form of recorded descriptions rather than numerical
measurements.
Correct Answer -Qualitative
