DESCRIBE A SCATTER WITH A NEGATIVE CORRELATION QUESTION OF THE DAY

AGENDA 1. Go over lesson 7 2. Lesson 8 notes 3. Group work with data 4. Lesson 8

When a pattern in a scatter plot is approximately, a line can be use to describe the linear relationship When informally fitting line, you want to find a line for which the points in the scatter plot tend to be close to the line. Best fit line

GROUP ACTIVITY In groups of 4-5 Draw scatter plot with given information Find and draw best fit line

ASSIGNMENT Example 2 exercise 7-9 Problem set #1-2 separate sheet of paper

EXIT TICKET If your best fit line is very close to many of you data points, what does that tell you about the relationship?
