According to this article, what is STATISTICS?

• Statistics is the universal language of the sciences that involves information, numbers, visual graphics to summarize information and its interpretation. In other words, the science of collecting, describing, and interpreting data.

• Statistics is a method of analyzing and collecting data that is not easily visible and must be described by using mathematics and other sciences.

• Statistics is using data, concluding data and making inferential theories from the information that has a positive normal distribution.

• Statistics involves using information, numbers, and descriptive conclusions to help businesses make corrective business decisions based on the descriptive techniques that create perfect graphs.

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 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

A statistic is...

• a planned activity whose results yield a set of data

• a numerical value that summarizes all of the data of an entire population

• the set of values collected from the variable from each of the elements that belong to the sample

• A numerical value summarizing the sample data

Which of the following statements about variables is correctly paired?

• A qualitative variable describes or categorizes an element of population, while a quantitative variable quantifies an element of a population

• A quantitative variable describes or categorizes an element of population, while a qualitative variable quantifies an element of a population

• A qualitative variable describes an element of the sample population, while a quantitative variable quantifies an element of total population

• A quantitative variable describes an element of the sample population, while a qualitative variable quantifies an element of total population
