POP QUIZ - INTRODUCTION OF STATISTICS

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.

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

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 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
