Task 13: Inserting a Chart<br />
The results indicate that participants’ ease-of-use ratings for inserting a chart are significantly<br />
higher for <strong>Excel</strong> than for <strong>StarOffice</strong> <strong>Calc</strong> (t (11) = 2.26; p < .05). In addition, two people failed to<br />
complete this task in <strong>StarOffice</strong> <strong>Calc</strong>.<br />
Explanation of the Problem<br />
Creating a chart is a multi-step process that many of our users don’t regularly complete. As such,<br />
they tended to run into problems both in <strong>Excel</strong> and <strong>StarOffice</strong> <strong>Calc</strong>. Generally, though, <strong>Calc</strong> charts<br />
took longer, caused more trouble, and were more likely to be incomplete or incorrect.<br />
In <strong>Calc</strong>, many of our participants:<br />
• Didn’t know how to begin the chart process.<br />
• Did not notice the chart icon in left toolbar. When they did, they had difficulties<br />
realizing they needed to click “Chart” once, then again on the place in the spreadsheet<br />
where they wanted the chart to appear.<br />
• Did not understand the “Labels in first column” checkbox.<br />
• Had a hard time altering the chart data range without starting over.<br />
• Had difficulties selecting the appropriate data range (see Task 14).<br />
