Some options:
- Call the Excel CHIDIST() function from Access using Automation
(requires coding skills). For more info, search the MS Knowledge Base
for "ACC: How to Call Excel Functions from Within Microsoft Access;"
- Invest in a statistical add-in such as FMS Total Access Statistics
(usual disclaimer...not affiliated, no compensation, yada yada yada);
- Dig out a reliable stat reference (e.g. Sokal and Rohlf) and "roll
your own" function. This requires coding and math skills.
