There is a new release of the Real Statistics Resource Pack, Rel 4.4.3 for Excel 2007, 2010, 2013 and 2016 environments, which corrects the following bugs:
Three Factor ANOVA data analysis tool: Fixes an incorrect p-value. Thanbks to Aaron for identifying this problem
FISHERTEST function: Fixes a bug which gave an incorrect p-value in certain situations. Thanks to Hoang for identifying this problem.
I am sorry for any inconveniences that these bugs have caused.
