Hi, I am planning a follow-up experiment to a previous study and have a question about estimating sample size: For the sake of simplicity, the previous study showed that Condition 1 had more accurate responses (64%) than Condition 2 (41%) and a paired samples t-test was significant...

Hi, I'm reading a paper about stats in psychology (https://www.ejwagenmakers.com/2007/pValueProblems.pdf) and there is an equation in there that I cannot work out. I'm not a mathematician, but as I understand, the binomial coefficient could be simpified as such: 1000! / 500!(1000!- 500!)...

OK so it's example 1? Or is there even a 'correct' choice? Example 2 might be more appropriate because it doesn't throw any data away i.e., it is calculating variance of every observation from the average. On the other hand, if we aren't allowed to use multiple responses from the same...

Yes, that's correct. Is example 2 still the best way to calculate SE?

Thank you for your response - it makes sense! PPT refers to participant (i.e., PPT 1 is data observed from first participant ,whereas PPT 2 is data from second participant, and so on). I expected this was the answer, but it is interesting because a lot of standard text books don't discuss this...

Hi, I would like to calculate the standard error of my Dependent Variable. However, I have psycholinguistic data, which uses multiple ppts and multiple items. Thus, there are 2 ways of doing this: either by calculating SE over averaged responses (example 1) OR by calcualting SEs over raw...
