Frequently Asked Questions

What operating systems does Data Desk support?

Data Desk 6.0 can be used with computers running Windows 95, Windows NT 4.0 and MacOS 7.0 or better.

Can Data Desk work with really large files?

Data Desk has a theoretical limit of about 2 billion cases. We don't know of anyone who has hit that limit but we do know of users who have analyse datasets with over a million cases. The most important factors effecting performance are the speed of your computer's processor and the amount of available RAM. Most computers should be able to analyse comfortably 25,000 data points

You can use the Data Desk demo to quickly check how Data Desk performs with large data files on your system. Launch the Data Desk demo and choose Generate Random Number form the Manip menu. Type the number of desired variables in the first field - about 5 is usually sufficient - and the number of cases in the second field - go ahead try a big number like 20,000 or 30,000. Press the OK button. Data Desk generates the random variables and opens the window holding the variable's icons. Now use the variables to create some plots or tables. Try a scatterplot, a regression or even a 3D rotating plot.

Can Data Desk open data saved in a spreadsheet file?

Yes, you can either copy the data from the spreadsheet and paste it into Data Desk or save the spreadsheet file as an ASCII text file and open it in Data Desk.
