What is the definition of statistics?

• The science of collecting, organizing, analyzing, and interpreting numerical information from data to understand uncertainty and reveal patterns.

• The process of drawing pictures from data.

• The act of guessing outcomes based on intuition.

Which of the following best describes a quantitative variable?

• A variable whose values are numerical and for which arithmetic operations such as addition, subtraction, or averaging are meaningful.

• A variable that describes a quality or category.

• A variable that cannot be measured.

• A variable that only takes on the value zero.

What is a sample in the context of statistics?

• The complete set of all individuals or items of interest in a statistical study.

• A subset of the population selected to represent and draw conclusions about the whole.

What is the difference between a parameter and a statistic?

• A parameter is a numerical summary calculated from sample data, while a statistic describes a population.

• A parameter is a numerical summary that describes a population, while a statistic is calculated from sample data to estimate a population parameter.

• Both are the same and can be used interchangeably.

• A parameter is always an estimate, while a statistic is always exact.
