Which of the following is a way of testing the predictive validity of an algebra test?

correlate test scores with the success of engineers

A commonsense definition of validity referes to an instrument that:

measures what it is supposed to measure

The sample in a particular study is the:

group on which the data are obtained

In a random sampling, it is necessarily true that:

each sampling unit has an equal probability of selection

1
Which of the following is a way of testing the predictive validity of an algebra test?
correlate test scores with algebra grades
correlate test scores with teacher ratings in Algebra
correlate test scores with scores on algebra homework
correlate test scores with the success of engineers
2
The recommended sequence for reading primary sources:
the most recent first
is to group the last 5 years and start anywhere among them
the oldest first
is to begin about ten years back
3
Reliability of measurement is concerned with:
consistency
proven value
relevance
systematic errors
4
A commonsense definition of validity referes to an instrument that:
yields consistent results on subsequent applications
measures what it is supposed to measure
discriminates adequately among high and low scorers
has been adequately standardized and has norms available
5
Random sampling is least effective when:
a convenience sample is used
a purposive sample is used
the sample size is very small
the population size is small
6
The sample in a particular study is the:
group that is selected
group that agrees to participate
group from which one selects a sample
group on which the data are obtained
7
Generalizing research findings from a sample to the population is most likely justifiable when:
a large random sample is used
cluster sampling used in a large, heterogeneous population
the null hypothosis is confirmed, regardless of the sampling
a small systematic example is used
8
In a random sampling, it is necessarily true that:
precisely similar samplings will be obtained if replicated
each sampling unit has an equal probability of selection
the sample will have a low variability
a representative sample with a normal distribution results
9
The first step in selecting a sample should be to:
define the population
decide how to stratify the population
determine how to randomize
compile a list of the populations
