3 / 3 pts The important difference between the ratio level of measurement and the interval level is:
the interval level has an absolute zero point, whereas the ratio level does not.
the ratio level has an absolute zero point, whereas the interval level does not.
variables at the interval level may be multiplied, whereas those at the ratio level cannot.
variables at the ratio level represent fixed measurement units, whereas variables at the interval level have open-ended units.

use of two or more different measures of the same variable.
phenomenon that occurs when a researcher recuses herself from a study.
combined validity and reliability of a study.
3 / 3 pts The ratio level of measurement identifies variables whose variables have no mathematical interpretation.
3 / 3 pts Level of measurement has important implications for the type of statistics that can be used in a study.
3 / 3 pts Data derived from historical documents or policy reports would be considered an unobtrusive measure.
3 / 3 pts Researchers choose levels of measurement in the process of operationalizing variables.
3 / 3 pts Research in which information is obtained through the responses that all available members of an entire population give to questions is called a: census.
3 / 3 pts The larger the , the less the findings. population; reliable

3 / 3 pts Completeness and saturation are two tests involved in _ sampling. quota
3 / 3 pts Sample generalizability refers to: the statistical results of a study.
whether or not findings from a sample of the population can be generalized to the population from which the sample was selected.
whether or not the findings from a study of one population can be generalized to another different population.
the diversity of the elements being studied.
3 / 3 pts What is the primary limitation of cluster sampling compared to simple random samples? The sample is not representative of the population.
The sampling error is greater.
There is too much homogeneity.
It is only a one-stage procedure.
3 / 3 pts Which type of sampling ensures that the sample represents certain characteristics in proportion to the population? quota
