Charts are visual representations of data. Charts are useful because they often make it easier to understand the data because users can pick out patterns and trends that are illustrated in the chart that are otherwise difficult to see. For this exercise you will analyze the changes in stock price for five different airlines. The data is provided for you. Go to the "Bus 1011 Excel Student Spreadsheets" and click on sheet labeled "Line Chart." Open the file and find the spreadsheet with Columns for each airline and Rows for each month. The data is the percent change in stock price over the course of the month. In order to compare the stock performance of the five airlines we will create a chart.
