In order to investigate to what extent the nuclear starburst or activity affects the host galaxy, a statistical investigation of the SNe discovered in Markarian, in Second Byurakan Survey (SBS), in north Galactic Pole (NGP) starburst or active as well as in NGP normal galaxies has been performed. 47 SNe in 41 Markarian galaxies, 10 SN in 6 SBS galaxies, 26 SNe in 23 NGP starburst or active galaxies, and 32 SNe in 29 NGP normal galaxies have been selected and studied. These studies include:
-Determination of the frequencies of SNe in all mentioned samples of galaxies. The computations make use of the control time method.
-Analysis of the integral properties of the SNe host galaxies.
-Analysis of the location of the SNe inside the host galaxies. This analysis includes, the comparison of the radial distributions of different type SNe, their associations with spiral arms and HII regions.
-As a further general exploration the Multivariate Factor Analysis (MFA) method to our samples has been applied.
The presentation will summarize and discuss obtained results
