Covers ANOVA, regression, t-tests, correlation, chi-square, factor and cluster analysis and more, all reachable from one entry point — you can type an abbreviation to jump to a method.
Drag in an Excel, SPSS or Stata file, drag the variables you need into the analysis slot, and click Start to get tables and a written report.
AI-generated interpretations explain what the output means in plain language rather than leaving you with raw statistics to decode.
Results come out in the tabular and graphical conventions expected in academic reporting, with a visualisation module offering 14 chart types such as scatter, box and error-bar plots.
