- On Windows versions prior to Windows 8, support for Excel *.xlsx files additionally requires Microsoft .NET Framework 4.0 (a free download from Microsoft).
- 2048 Mb of memory.
- 60 Mb free space on the hard disk.
- After you have downloaded MedCalc from our website, you locate the setup file medcalcsetup[32/64].msi on your hard disk and execute (double-click) it.
- This installation procedure will create a directory named MedCalc (or another directory you have selected during the installation procedure) on your hard disk, and copy the program files to this directory. In addition, it will create a sub-directory for the program's data files.
- When installation is complete, you start MedCalc by clicking the Start button and point to Programs, next click MedCalc.

When you want to obtain summary statistics for the variable Weight, click Summary statistics on the Statistics menu. The following dialog panel appears on the screen:
In this dialog panel you can identify the variable to be analyzed. You can click the button to obtain a list of variables.
From this list you can select a variable by clicking the variable's name:

or you can enter a formula combining different variables, e.g.
Optionally, you may also enter a filter in the Select field of the dialog panel, in order to include only particular cases in the statistical analysis.
The filter may contain a combination of different criteria, using the AND and OR functions, e.g.
