A Statistic (note: not statistics) is:

• a numerical value that describes a characteristic of a sample

• the study of collecting and analyzing data

• a numerical value that describes a characteristic of a population

• a graphical representation of data

A Qualitative Variable is:

• A variable that describes qualities or categories rather than numerical values.

• A variable that can only take numerical values.

• A variable that measures time intervals.

• A variable that represents only whole numbers.

A Quantitative Variable is:

• a variable that can be measured numerically

• a variable that describes categories or groups

• a variable that cannot be measured

• a variable that only takes on names or labels

The Nominal Level of Measurement (or scale) is:

• a scale that categorizes data without any order or ranking

• a scale that measures data with a true zero point

• a scale that ranks data in a specific order with equal intervals

• a scale that measures data with both order and meaningful differences between values

The Ordinal Level of Measurement (or scale) is:

• a scale that categorizes data with a meaningful order but without a consistent difference between categories.

• a scale that measures data with a true zero point and equal intervals.

• a scale that categorizes data without any order.

• a scale that measures data using only names, labels, or categories.
