Descriptive statistics involves...

• collection, presentation, and description of sample data

• the technique of interpreting the values resulting from the descriptive techniques and making decisions and drawing conclusions about the population

• attempting to provide incorrect information and provide misleading graphs

• using information, numbers, and graphics even when data can't be collected

Inferential statistics involves...

• collection, presentation, and description of sample data

• the technique of interpreting the values resulting from the descriptive techniques and making decisions and drawing conclusions about the population

• attempting to provide incorrect information and provide misleading graphs

• using information, numbers, and graphics even when data can't be collected

The POPULATION in statistics is best described by...

• a collection, or set, of individuals, objects, or events whose properties are to be analyzed

• the total number of people that live in a particular city

• the incomplete collection of individuals or objects that are of interest to the sample collector

• a collection of people that are being analyzed for membership on a list of particular elements to be studied

A sample is...

• a subset of a population

• an infinite selection of a population

• a characteristic of a population

• a data value generated by the statistical information

A variable (or response variable) is

• a characteristic of interest about each individual element of a population or sample

• a characteristic that is irrelevant to the collection of the data

• a characteristic that changes when the data is collected

• a characteristic or trait that will be ignored in a sample population
