robkaz That is true for a 2-tailed test but not necessarily true for a 1-tailed test.
surob I think it doesn't matter whether it is one tailed or 2 tailed. What matters here is that calculated F statistic is less than test statistic.
tom1980 how about the null hypothesis you make ?
TheHTrader Is the calculated F statistic = critical value (by looking up the table of f-distribution? I am a little confused here.
jpducros For a F-Statistic, there is only a one-tail test possible, the right tail.
