[R11-QUAN] LONG TEST

When researchers describe the information contained in many scores with just a few indices, such as the mean or median, and these are calculated for a sample drawn from a population, they are called

• statistics

• parameters

• modes

• analysis

If a researcher selected five schools at random and then interviewed each of the teachers in those five schools, the researcher used

• Simple random sampling.

• two-stage random sampling

Which of the following is an example of a random sampling method?

• systematic sampling

• convenience sampling

• purposive sampling

• cluster random

Which of the following is not an example of a random sampling method?

• systematic sampling

• stratified random sampling

• simple random sampling

• cluster random

A simple random sample is a sample selected from a population in such a manner that all members of the population have an equal chance of being selected.

• TRUE

• FALSE

When a study is replicated, it is repeated with a new sample and sometimes under somewhat new conditions.

• TRUE

• FALSE

A group of individuals that is conveniently available to be studied is called a systematic sample

• TRUE

• FALSE

The best construct-related evidence of validity comes from

• a series of studies of the instrument

• a validity coefficient that is near 0

• careful review of the instrument by experts

• data-based predictions that prove to be correct

Which of the following is not one of the three best-known ways to obtain a reliability coefficient?

• test-retest

• equivalent forms

• internal consistency

• concurrent

If a researcher wishes to obtain content-related evidence of validity, a common way to do this is to

• have a friend look over the instrument and give feedback.

• obtain a Kuder-Richardson analysis.

• review the instrument very carefully.

• have an individual who knows enough about what is to be measured review the content and format of the instrument and judge whether it is appropriate.
