Data Desk/XL
Fast, Reliable Results, Expert Guidance
There is no doubt about it - Excel is one powerful tool. However, it
does have its limitations. Data Desk/XL(DDXL) is a downloadable
statistics add-in that complements Excel's standard statistics
capabilities. It can be used effectively for analyzing real-world data
and as a supplement to an introductory statistics course.
Fast
All results are two to three mouse clicks away. Just select the columns
you want to analyze, choose the desired command from the DDXL menu in
your Add-Ins menu bar, assign the variables in the dialog box and click
the OK button.
Reliable Results
All DDXL computations are based on algorithms that have been used and
validated with real data for over 25 years. Statistics 101 classes
around the world have been using DDXL for decades because of that
accuracy.
Expert Guidance
Each statistical function includes a predefined template written by
statistics experts that offers guidance for working with your data and
helps you interpret the result.
