Data that are either qualitative or quantitative and can be arranged in order. However, differences are not meaningful.

Information coming from observations, counts, measurements, or responses.

The branch of statistics that involves using a sample to draw conclusions about a population

Data that are quantitative and meaningful differences can be calculated. No inherent zero can be found.

A numerical description of a sample characteristic.

Data that are qualitative and cannot be ordered. Mathematical computations cannot be made at this level.

Data that consists of attributes, labels, or nonnumerical entries.

The collection of all outcomes, responses, measurements, or counts that are of interest.

The branch of statistics that involves the organization, summarization, and display of data.
