2. Catalyst 1. Why is it important to set up a consistent interval on both the X and Y axes before making a scatterplot?

3. Page 33 Both axes should be set up

4. Page 34 Graph Create your graph for your diameter and circumference data. Don’t forget labels, a title, and appropriate intervals on both axes

5. Plot your points

6. Line of Best Fit What is a line of best fit? A line on a scatterplot showing the general direction that a group of points seem to be heading. There should be equal numbers of data points on either side of the line.

7. Graphical Analysis

8. Homework Complete a final Circumference vs Diameter graph on a separate sheet of graph paper, using a pencil and a ruler

10. Catalyst Copy the 2 graphs drawn above onto your Catalyst sheet, then answer: What is the difference between the two graphs drawn above? What is similar about them? Write down any and all similarities/differences that you can come up with.

11. Graphical Analysis

12. Slope Slope is the steepness of a graph line. It is the ratio of the vertical change (the rise or change in y) to the horizontal change (the run or change in x). The equation for finding slope is m = (y 2 -y 1 )/(x 2 -x 1 ).

20. Homework Final lab report, with rubric attached to front, due Friday. Lab will not be accepted without a rubric. All sections need to be typed, except the Apparatus, Raw Data Table, and Data Analysis Table may not be. The Graph should not be made on the computer. Please use the Model Lab Report as a guide. Please print a new rubric if you have lost yours.
