Soft where?

This is the page, read all about it— how to get yourself rigged up with a copy of Lertap.

Lertap will run on (almost) any computer which can run Microsoft's Excel program. Excel is one part of a suite of programs generally referred to as "Microsoft Office"; other components of Office are Word and PowerPoint.

Excel-lent stuff

Is there a link between Lertap and Excel? Most definitely. Absolutely. Totally. Lertap is a data analysis application written to work hand in glove with Excel. This has all sorts of advantages; Lertap leans on Excel for data processing oomph— when Lertap needs to have some calculations done, it often gets Excel to do them. Almost all of Lertap's graphs are really Excel charts, and Excel has some good chart-making capabilities.

Do you have to be an Excel whiz to use Lertap? Not at all. Not a bit. Lertap fronts up to Excel on your behalf. You could think of Excel as the motor to your car. Lertap is the car. It's got posh seats,a great music system, is easy to drive, and runs on green tea. You don't need to know anything about the motor.

On the other hand, if you like to tinker with motors, you can. If you have some Excel experience, you'll know that it's easy to make charts, and you might use a bit of your innate creativity to highlight bits of Lertap's output, getting Excel to make a nifty new chart or two for that special paper or PowerPoint presentation you've been working on. (Can be addictive.)

Versions

There are a few versions of Lertap. Most are for use with Windows versions of Excel, but there's also a version which runs on Macintosh computers via Excel 2011.

All versions of Lertap for Windows are available at Assessment Systems Corporation, a commercial site which offers free 30-day trials.

A 'Mini' version of Lertap for use with Excel 2010 and Excel 2013 is available using links from Curtin University in Western Australia. The Macintosh version is also available from Curtin.
