QData: Data Entry Almost Without Pain

QData is a flexible and powerful freeware program for data entry and management. Written by Jesse Reichler and Dean Savage to satisfy the need for a simple, portable, and inexpensive means for researchers on all levels to prepare small to medium sized data sets for analysis, it runs on PCs under DOS.

It was designed to work with other packages. Once you have defined your variables and entered your data, QData can write data definition and data files for SPSS and SAS, and will also write dBASE and ASCII files. It will also automatically generate codebooks. The program works in the other direction as well -- you can load SPSSPC system files, SAS transport files, dBASE files or, after defining the variables, ASCII data sets. You can then easily modify or add to these data sets.

You can also explore and analyze your data using QStats, which can make direct use of data files entered with QData. QStats is designed for ease of use and makes extensive use of graphics (histograms, mean charts, scatterplots, and boxplots). It offers a quick way of exploring most data sets and is also available at this site.

NOTE: qstats.zip is in zipped format, you will need to unzip it using PKUNZIP.EXE. Retrieve pkunzip.exe if you don't have it already.
