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.

throwing out data that does not fit the graph

carefully defining the situation

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

an infinite selection of a population

a characteristic of a population

a data value generated by the statistical information

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

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

a planned activity whose results yield a set of data

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

A numerical value summarizing the sample data

A discrete variable...

a quantitative variable that can assume a countable number of values, in other words, there is a gap between any two values

is a qualitative variable that characterizes, describes, or names an element of a population

is a qualitative variable that incorporates an ordered position, or ranking

a quantitative variable that can assume an uncountable number of values, in other words, it includes every possible value between any two values

A continuous variable...

a quantitative variable that can assume an uncountable number of values, in other words, it includes every possible value between any two values

is a qualitative variable that characterizes, describes, or names an element of a population
