Define Ratio Variable.

A variable having values that are numbers which reflect quantities or measurements.

A characteristic from a sample or population that can assume different values for individual elements (members) of the sample or population.

A quantitative variable such that ratios of its values are meaningful and for which there is an inherently defined zero value.

Facts and figures from which conclusions may be drawn, generally for a specific study or issue.

2.

Define Inferential Statistics.

Efforts to mislead users of statistical information including biased sampling, misleading chart, table and descriptive measures, and inappropriate analysis or inappropriate interpretation of the results.

The process of using a sample of measurements/values to make generalizations about the important aspects of a population of measurements/values.

A sampling design in which we divide a population into subgroups that do not overlap, then select a random sample from each subgroup (stratum).

A sample selected in such a way that every element in the population has an equal chance of being selected.

3.

Define Variable.

5.

Define Sample.

The process of organizing and describing important elements of a set of values.

A sample selected in such a way that every element in the population has an equal chance of being selected.

The process of using a sample of measurements/values to make generalizations about the important aspects of a population of measurements/values.

A subset of the elements in a population.
