The Cochran’s Q test is used to find out whether more than two related binary measures from the same group or units are statistically different or not. Binary means that only values 0 and 1 are allowed. It is the extension of the McNemar Test to more than two measures. The Cochran’s Q Test assesses whether the proportion of value 1 is the same between the related measures. There are no assumptions to this test, however your sample size should be large enough.
