Statistics Assessment

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

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

Careful use of statistical methods does not include....

• carefully defining the situation

• gathering data

• summarizing the data accurately

• deriving and communicating meaningful conclusions

• throwing out data that does not fit the graph

What is not a usual question to ask when conducting statistical analysis?

• If the data does not give me the results I want do I still trust the results?

• Where did the data come from, what is its source?

• What kind of surveys were conducted, if any?

• Are the results of the data reliable?

Statistics are used...

• in education

• in science

• in government

• in mathematics

• all of the answer choices

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 finite population is one that...

• can be physically listed

• the membership in the population is unlimited

• ends abruptly due to a catastrophy

• ends abruptly due to natural causes, such as a flood or the ice age

An infinite population is one that...

• can be physically listed

• the membership in the population is unlimited

• ends abruptly due to artificial intervention, such as treating with an antibiotic

• ends abruptly due to natural causes, such as a flood or the ice age

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
