Lists I-IX of Markarian galaxies have been used as the basic observational material. An attempt has been made to form a statistically complete sample. Two regions (region I 6h.8 < α < 14h.2, 41° < δ < 77°, region II 6h.8 < α < 13h.9, 5° < δ < 32°) which appeared to be roughly complete have been carefully examined. After preliminary tests the first two hours in R.A. of the region II were removed from the analysis. the method of statistical reduction (Flin et al. 1974, A. Zieba 1975) and the maximum likelihood estimate of the number-magnitude counts (Crawford et al. 1970) were applied as a combined test in their practical version (Urbanik 1976, 1977). We have examined the whole region, as well as a number of smaller sub-regions varying in size and position. the angular sizes investigated ranged from 1° up to 30°. Our analysis of 15 galaxy sets led to the following conclusions.
