Cochran's Q Test Calculator with Post-hoc Analysis

Please click to add a treatment.

Cochran's Q test is a non-parametric statistical test used to test whether a number of dependent treatments have identical effects, and is used for dichotomous data (expressible as numbers with a value of either 0 or 1). This test can be regarded as an extension of the McNemar test.

Should the calculated p-value be less that 0.05, a cursory post-hoc analysis is carried out by performing pairwise McNemar tests on the treatments. Any resulting p-value less than 0.05 is highlighted by two asterisks.

Simply click on the link near the top to add text boxes. Each text box stores a single treatment and needs to be filled in with comma separated numbers, which take value 0 or 1. All treatments need to have the same number of samples, which is equal to the number of blocks.

Alternatively, you can choose two file entry methods:-

  1. Select multiple single column CSV files to populate the text boxes by repeatedly pressing the Choose File button - there must be one distinct (and differently named) file for each text box i.e. one file per group. Each file can have a different number of samples.
  2. Select a single multi-column CSV file by pressing the Choose File button once, where the number of columns equals the number of groups - all groups need to have the same number of samples.

  1. I am excited to share this testimony, I was 3 years ago diagnosed of fibroid and complicated Endometriosis. My medical condition was heart broken because it was causing my menstrual cramps,bloating before menstrual periods,lower abdominal pressure which result to heavy periods. I was subjected to different medications by my doctor for treatment . Despite my visit to several doctors my health wasn't getting better, all they could say was surgery. At the verge of giving up, I went to the internet to search for a treatment at least. But I found a cure instead. In the internet, I read a testimony of a lady who had Fibroid. She shared an e-mail address of the Doctor. Luckily everything seemed to be okay after I took the Herbal Medicine. I wish I could say that’s the end of it because I haven't had any symptoms since then. Do not expose yourself to more danger, use a herbal remedy that is safe and effective.
