AcaStat 9 statistical software 

AcaStat 9 is an inexpensive and easy-to-use data analysis tool. Easily create data files or import data from spreadsheets or delimited text files. Run crosstabulations, descriptive statistics, correlation, and common significance tests without learning programming code or complex interface commands.

AcaStat 9 includes an intuitive data analysis interface, a chart module, and practice data files.  A statistics glossary is provided along with an on-line How To Guide.  All output is stored in an output log to view, save, and print results. 

The Windows version is designed to work with Windows 8.1 touch screen technology.  The Mac version may be purchased through this site or from Mac App Store.

AcaStat at a glance

Explore Data with Drag and Drop

Drag and drop variables into the labeled boxes and AcaStat automatically runs the selected statistical procedure. Key summary statistics are displayed in the Explore tab for quick review. Build regression models by incrementally adding variables to the model. The copy button in Explore will copy selected rows of output or, if no rows are selected, it will copy all of the list box contents. Copied contents can easily be pasted into a spreadsheet or word processor to assist in report writing and editing.

Visualize Summary Statistics

Explore charts are automatically produced for five statistical procedures. A horizontal bar chart for frequencies, a histogram for descriptives, a scattergram for correlation, a histogram of residuals for OLS regression, and an ROC curve for diagnostic accuracy. Chart data are retained for descriptives, correlation, and OLS regression. Click on a prior analysis to view the chart for that analysis. Click on a chart to edit, print, copy, or save. Additional statistics are recorded in the Output Log.

Enhance Analyses with the Options Panel

The Options Panel displays variable list boxes, analysis options, and control settings. Select multiple variables for analysis, remove variables from analysis, set controls, and choose options such as saving regression residuals or reducing cell contents in crosstabulations. A running history of analyses is displayed alongside the Options Panel for each statistical procedure. The output is retained until the procedure is reset or AcaStat is closed.

View Variable Information

The Explore tab displays file information and a data dictionary for the loaded data file when AcaStat is maximized or reaches a width sufficient for proper display of the dictionary panel. This feature allows quick review of variable information alongside the analysis module and is especially useful for files with a large number of variables. The data dictionary can be edited with the format module in the Data tab.

View variable information
Create and Format Data

The Data tab permits creating and editing data files with hundreds of variables. The Format module is displayed in the Data tab to the left of the data spreadsheet. Click on a column to view and edit variable formatting. Set missing values and format up to 12 value labels. Use the Recode module to create new variables from ranges of values, compute new variables, find and replace spreadsheet contents, and run optional transformation procedures (log, exponent function, mean centering, standardizing).

Create and format data
View Output

The Output Log tab displays the results of the analyses in a text window for editing, printing, and saving as a text file. Each time a statistical procedure is run, the results are automatically sent to the Output Log. Notes can be added to the output before printing or saving. The option to convert output to tab delimited format enables pasting into spreadsheet software while retaining proper column alignment.

View output
Create Charts

The Charts module produces graphic displays of data. The chart can be saved, printed, and copied by using the toolbar buttons or menu pull-down. The chart can also be formatted to adjust background, titles, and decimals. A control variable can be used to chart subgroups of data.

Create charts
Get Procedure Help

An on line How To Guide is accessible by clicking the toolbar button. The How To Guide provides instruction on how to set up the Options Panel variable boxes to run each statistical procedure. The instruction explains the purpose of the procedure, displays an example of the output, provides an example of the data format, and shows how to set up the analysis list boxes. The How To Guide is also available as a pdf download from the Documentation pull-down menu.
