1.1-1.2 Definitions

data

• numerical description of a sample characteristic

• a subject, or part of a population

• a numerical description of a population characteristics

• consists of information coming from observations, counts, measurements or responses

statistics

• a subject, or part of a population

• the science of collecting, organizing, analyzing, and interpreting data in order to make decisions

• the collection of all outcomes, responses, measurements, or counts that are of interest

• the branch of statistics that involves using samples to draw conclusions about a population.

population

• a numerical description of a population characteristics

descriptive statistics

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

• the branch of statistics that involves using samples to draw conclusions about a population.

• numerical description of a sample characteristic

• the collection of all outcomes, responses, measurements, or counts that are of interest

inferential statistics

• consists of information coming from observations, counts, measurements or responses

• the branch of statistics that involves using samples to draw conclusions about a population.

• the science of collecting, organizing, analyzing, and interpreting data in order to make decisions

• a numerical description of a population characteristics

qualitative data

• consists of numbers that are measurements or counts

• can be ordered and meaningful differences between data entries can be calculated. a zero entry simply represents a position on a scale. the entry is not an inherent zero.

• consists of attributes, labels, or no numerical entries

• a zero that implies “none”

quantitative data

• can be ordered and meaningful differences between data entries can be calculated. a zero entry simply represents a position on a scale. the entry is not an inherent zero.

• consists of attributes, labels, or no numerical entries

• a zero entry is an inherent zero. a ratio of two data entries can be formed so that one data entry can be meaningfully expressed as a multiple of another.

• consists of numbers that are measurements or counts
