On the whole a larger sample size consisting of both male and female, different religions, race and occupations would improve the ecological validity of the study as it would mean that you could generalise the results to the public as there would be a percentage of people in the study representing the different races, sexes, occupations thus being able to generalise the findings from the study to real life.
