Product testing with multiple matched samples is often encountered. If the response for each sample is binary, the test involves comparison of multiple proportions of dependent samples. In the paper, a test statistic due to Bennett (1967, 1968) is discussed and extended to the replicated testing situation. An adjusted Bennett's statistic is proposed based on the Dirichlet‐multinomial distribution. The conventional and adjusted Bennett's statistics are illustrated by a numerical example in product testing.
