Primer<br />
• Podjetje želi proučiti vpliv stroškov<br />
propagande, števila prodajalcev v prodajalni<br />
in stroškov promocije na prodajo izdelka. V ta<br />
namen so zbrali podatke o prodaji v 10<br />
prodajalnah, podatke o stroških za<br />

prodajalnah in podatke o stroških za<br />
promocijo prodaje.<br />
