Unit 4 Vocabulary

data for two related (numeric) variables that can be represented by a scatterplot

• Correlation coefficient (r-value)

• Linear equation in two variables

• Quantitative bivariate data

• Continuous function

numeric value that assesses the strength of the linear relationship between two quantitative variables in a set of bivariate data

• inequality notation

• Correlation coefficient (r-value)

• x-intercept

• y-intercept

function whose values are continuous or unbroken over the specified domain

• continuous function

• discrete function

• linear function

• inequality notation

a relationship or correlation between two measurable variables

• association

• causation

• correlation

• range

a relationship between two variables in which one variable directly causes change(s) in the other variable

• range

• causation

• correlation

• domain

description of the linear relationship between the two variables in bivariate data

• correlation

• causation

• zeros

• domain

a linear relationship between two variables, x (independent) and y (dependent), that always has a constant, unchanged ratio, k, and can be represented by y = kx

• linear function

• inequality notation

• Direct variation

• continuous function

function whose values are distinct and separate and not connected; values are not continuous. Discrete functions are defined by their domain.

• discrete function

• linear function

• continuous function

• association

set of input values for the independent variable over which the function is defined

• domain

• range

• x-intercept

• y-intercept

notation in which the solution is represented by an inequality statement

• inequality notation

• Direct variation

• Discrete function

• Continuous function
