Scatterplots

scatterplot

graph that depicts the relation between two variables

interpolation

estimating a value that falls between two known values

extrapolation

the act of estimation by projecting known information

discrete data

data, such as shoe sizes or numbers of pets, that can take only certain values

continuous data

measurement data, such as heights or weights, that can take any value within a range

correlation

the relationship between variables

causation

A cause and effect relationship in which one variable controls the changes in another variable.

line of best fit

a smooth line that reflects the general pattern in a graph

correlation coefficient or "r

a number between -1 and +1 expressing the degree of relationship between two variables

dependent variable or "y

the variable that is affected by the other variable in the data

independent variable or "x

the variable that is in "charge"; it determines what the dependent variable will do and is the one manipulated in an experiment
