The standard error of the mean is the same thing as

the standard deviation of a sampling distribution

Compared to probability samples, non-probability samples

are usually cheaper to assemble.

Social scientists gather data from samples instead of populations because

populations are often too large to test

The main problem with non-probability samples is that they

do not allow us to generalize to a population.

If a sample is random it

reproduces the characteristics of the population

1
The simple random sample requires
a defined population
All of the above
a complete list of all cases in the population.
a random selection process
2
The standard error of the mean is the same thing as
the standard deviation of a sample.
the standard deviation of a population
the variance of a sample
the standard deviation of a sampling distribution
3
Compared to probability samples, non-probability samples
allow for generalizations to populations
are always much larger
are usually more expensive to assemble
are usually cheaper to assemble.
4
Unless a sample is ______, it cannot be used to make accurate generalizations to a population.
non-probability
very large
stratified
representative
5
Social scientists gather data from samples instead of populations because
samples are more meaningful and interesting
populations are often too large to test
samples are more trustworthy
samples are much larger and more complete
6
The main problem with non-probability samples is that they
are much too large
do not allow us to generalize to a population.
are far too expensive
can only be assembled using the cluster sampling
7
Statistics are to parameters as
percentages are to proportions
populations are to samples
samples are to populations
medians are to standard devlation
8
If a sample is random it
is restricted to the calculations of parameters only
is stratified
reproduces the characteristics of the population
resembles the sampling distribution
9
The goal of all techniques for selecting probability samples is to select samples that are
easily located
representative
non-random
very large
10
A properly selected cluster sample is
quite small
non-probability
EPSEM
the population
