1. Intro to Biology Unit 1 (Chapter 1) The Basis of Life Graphing

2. How to set-up graphs… The MEAP raw scores are an important way to measure how successful we are as a school. If we examine the raw scores over the course of several years, hopefully we will see a positive pattern. Here is data from a school from 2005-2010. Year200520062007200820092010 Score815847824805846839

3. Start with a title…be specific

4. Lab graph Too vague Is this title good? Or too vague?

5. Scores Too vague Is this title good? Or too vague?

General Rule : If you are showing changes over a period of time, you will make a line graph. General rule : If you are comparing more than one set of information, you will make a bar graph. So what should we make here?
