The resulting contingency table makes it slightly easier to compare the proportion of people in each category. For example, we see that the two largest proportions in the table (.399 and .271) are in the yes/yes and no/no cells of the table. We can also see that almost 40% of the surveyed population (by far the largest proportion) both see themselves as leaders and think they have a talent for influencing people.
