Accuracy

The distance between a datum and the intended or correct value

Biased Sample

Data that is invalid due to preference or ignorance of a certain variable or variables. Variables may be precise, but not accurate.

Independent

When one variable has no effect on the probability of another variable being chosen.

Population

The entire whole a sample is supposed to represent.

Precision

How clustered data points are to each other.

Random Sample

A group selected to represent the population that was selected without bias.

Statistical Interference

When the population is grouped into a conclusion based on the results of a sample.

Statistics

The organization of data to quantify how applicable the data is to the population.

Stratified Random Sample

Different confounding variables within a sample cause subgrouping within a sample.

Sample

A group taken out of the population to create generalizable data meant to apply to the population as a whole.

Attribute

The categorization of data through the appearances, descriptions, or actions of variables.

Binary

The name given to a variable description that only has two possible categories.

Categorical

The method of describing qualitative data without measurements.

Variable

A piece of data or quality that varies throughout a sample.

Continuous Measurement Variable

Any possible value to an infinite degree within a provided range.

Data

The results provided from a sample in a measurable manner.

Datum

A singular result of a study.

Derived Variable

The combination of two variables to form a ratio that illustrates the relationship between the two variables.

Metadata

The key for humans and computers to understand abbreviations within recorded data.

Outlier

A result that does not follow the trend of the other results.

Predictor or Explanatory Variable

A variable that influences the results of another variable.

Ranked or Ordinal Variable

A categorical variable that requires a numerical position to measure data.

Response Variable

A variable dependent on the outcome of a previous measured variable.

Sample Size

The quantity of objects selected to represent the population. Measured with ( n= )

Significant Figure

The quantity of numbers present in a datum required to accurately represent the precision of a sample.

Spreadsheet

The method used to organize data by utilizing rows and columns.

Transformation

The alteration of a variable through a mathematical equation to make the variable more easily accessible.

Nominal

Data organized without numbers or logic, categorized by name, placement, etc.
