The API scores of BHHS is an important way to measure how successful we are as a school. If we examine the API scores over the course of several years, hopefully we will see a positive pattern. Here is our data from 2005-2010.

How to choose a bar or line graph?

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?

Line Graph is best in this situation because we will track the school data over the time length of 2005-2010
