AcaStat is a user-friendly and affordable data analysis software suitable for students, teachers, managers, and researchers. It caters to basic analytical needs and is available for both Mac and Windows. A limited version is also offered.

One of the standout features of AcaStat is the ability to create and analyze crosstabulations, basic significance tests, descriptive statistics, and summary reports. I found this to be incredibly useful for producing basic summary statistics in my work.
The software also offers the option to create data files or import from spreadsheets or statistical software. Additionally, it comes equipped with a summary statistics module to analyze counts, proportions, and means.
For those who want to dig deeper, AcaStat offers a range of statistics procedures including Frequencies, Descriptives, t-tests and ANOVA, Chi-square and association measures, Correlation, OLS and Logistic regression, Random sampling, and Diagnostic Accuracy.
AcaStat is available on both Mac and Windows platforms, although it should be noted that the demo functionality is limited. Nevertheless, the printable manuals include a Student Workbook with over 20 lessons and an AcaStat User Manual.
I also appreciated the software's ability to analyze raw data within a spreadsheet design, produce descriptive and inferential statistics, and create crosstabulations. The software includes a range of features such as Import/Export comma and tab delimited text files, Filter observations and use control variables, Split large data files, Format variable and value labels, set missing values, and Compute, combine, and recode variables.
Overall, I would recommend AcaStat statistical software to anyone looking for a low-cost alternative to producing basic summary statistics. Its user-friendly interface and range of statistical procedures make it a versatile and valuable tool. The only thing to keep in mind is that the software requires Mac OS X v. 10.11 or later.
