Catalyst1. Why is it important to set up a
consistent interval on both the X and Y axes before making a scatterplot?
Page 33
Both axes should be set up
Page 34
Graph
Create your graph for your diameter and circumference data.
Don’t forget labels, a title, and appropriate intervals on both axes
Plot your points
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.
Graphical Analysis
Homework
Complete a final Circumference vs Diameter graph on a separate sheet of graph paper, using a pencil and a ruler

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.
Graphical Analysis
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 = (y2-y1)/(x2-x1).

As X increases, Y increases proportionally.
Y is directly proportional to X.
y = mx + b

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.
