    sample size calculation for paired proportions when one discordant pair is 0

    Hello! I am trying to calculate sample size for a study using paired data. My groups are such that one discordant pair will always be 0. I planned to use McNemar to test for a difference between the groups, however, I am not sure this is valid since one discordant pair will always be zero...

    McNemar test and all the variations, is mid-p indeed the best?

    After a long search I think I finally got this right, but would like to know for sure. I've been trying to sort out all the variations on the McNemar test. What I've found so far: McNemar test as proposed by McNemar himself in 1947 uses a chi-square distribution. As such a continuity...

    2x2 contigency table non-independent but not paired data

    I am looking at male-biased sexual size dimorphism in a bird species (males average larger than females). I am interested in the proportion of males larger than females in breeding pairs. I have one proportion result "A" from observed breeding pairs. I then did random bootstrap resampling...

    Comparing proportions from the (somewhat) same sample

    Hi everybody, I’m looking for some help on testing whether there are statistical differences between proportions when the data is dependent. By dependent, I mean that all the data is from the same participants though I’m not talking about a repeated measures experimental design but instead...

    Are McNemar's and Binomial the right tests for my data

    Hi everyone. I have performed an experiment, where I have real and synthesised movie data. My participants were shown either a real movie, or a synthesised movie (of talking heads), in a random order, and had to guess whether the movie was real or synthesised. I have 17 participants, each...

    Mcnemar's test for dichotomous IV vs. dichotomous DV: how pertinent is it?

    I intend to study the effect of a given psychological intervention (dichotomous independent variable) on the compliance of a medical treatment (dichotomous dependent variable). For this purpose, the compliance of a number of patients will be “measured” in two different moments (say M1 and M2)...

    single-case study

    Dear friends, I am running a single case study. I am collecting correct and incorrect responses on two similar tests in 3 moments in time. I would like to know two things: - if there exist significant differences between each of the three times within each test and where are those...

    McNemar Test HELP!

    Please forgive my ignorance and sophomoric knowledge of this but I only know of this test that is used for multi-conditions. I have a 3x3 table that has condition 1 and condition 2 Can I use a McNemar test on this and if so how. If not what is the best thing to do on this?

    McNeamar versus Chi-square

    Hi everyone, I am having a little trouble understanding the difference between the assumptions behind the McNemar Test and an ordinary Chi-square test. The text books say "use McNemar when the data is paired" but it doesn't seem totally clear what this really means. My understanding of...
