If the distribution of responses were normal, we would expect to see a roughly even split between those in favor, undecided, and against same-sex marriage. A flat distribution would indicate that there is no variation in responses, which is unlikely. A bimodal distribution would suggest that there are two distinct groups of people with strongly opposing views. A skewed distribution where most responses are in favor of same-sex marriage would be consistent with the researcher's conclusion.
