    Can't wait to use ANOVA and Test on some data I'm tracking. Thanks for the videos. They're great! Very well presented and concise. Well done to you and thanks again!

    9:18 "The alternative hypothesis that they are all not equal" should be "The alternative hypothesis that they are not all equal"

    thanks for the aside about the coasters. the wooden ones have an extra "scare" factor. giant dipper in santa cruz is one of those, but the King is over a mile?!? I love it. Thanks for these videos. you rock.

    4:24 what if the 3º value is not relevant for the comparison between 1 and 2, in addition to be completely independent from the 2º value? And the variance of these 3º value is masking the difference between 1 and 2?

    8:51 when I put the same table in excel and run one way ANOVA: Single Factor, it gave me different results. I am facing problems with these statistical techniques when I perform them in excel. Please help me

    At 7:57 point three: shouldn't it be "sample pair" instead of "population pair"?

    I find it hard to understand the part with error compounding. I mean, I know that in probability if two events are independent and have let's say a probability of 0.05 of happening (In our case Type One Error). Then if we want to repeat the experiment let's say 3 times, then we set P(Error) = 0.05 and then we have 0.05 ^3 = 0.0125%. So at the end we decreased our P(E) by repeating the experiment 3 times. I'm I getting something wrong here, can your please help me understand this concept? Thanks.

    please Foltz what can I do if my data is non-normally distributed? what is the best method can I use instead of two-way ANOVA.

    Morning sir,
    Which Post Hoc Test can we use for a TWO WAY ANOVA? W/O replication
    thanks.

    please explain when the 0.5 significance level is compounded, and when not. I see you doing t tests comparing each one individually in this video. Please help

    A brilliant video like all your other videos. Thanks very much. One question. In this video, you compared the groups pairwise to identify which differences between the groups was significant. But what about the Type 1 error multiplicative effect for 3 groups. Why is this not a factor here?

    But where does this formula come from what's the theory behind it ?

  • @karannchew2534
    @karannchew2534 3 роки тому

    "Fisher’s LSD, which is the F test, followed by ordinary t-tests among all pairs of means, but only if the F-test rejects the null hypothesis. The F-test provides the overall protection against rejecting H0 when it is true."
