11.2 Scatter Plots

Scatter Plots

Example: What is the relationship here? Is the data on the x-axis related to the data on the y-axis? Is there a relationship between height and shoe size?

There are 3 types of relationships. A positive correlation A negative correlation No correlation This means as x is increasing, y is also increasing This means as x is increasing, y is decreasing This means there is no relationship between x and y

A positive correlation as x is increasing, y is also increasing

A negative correlation as x is increasing, y is decreasing

No correlation No relation between x and y Peanut butter

When making a scatter plot, all the regular graphing rules applied.

What type of correlation do you think the following data sets have? Study time, grades Age of car, value of car Height, intelligence Shoe size, salary Miles per gallon, gas expense Windchill, ice cream sales
