What is one take-away you have from any of the data you reported? Did you find any of the findings surprising? Did any of your findings confirm your hypotheses?
The data compare characteristics of people who are leaders versus those who are not leaders, but we do not have data on whether the leaders are considered “good” leaders. How might we better determine whether a person is effective as a leader or not?

Based on the findings, altruism and variety had non-significant scores for leaders and non-leaders. On other hand, leaders and non-leaders scores for independence and management were significant different. On personality, the leaders and non-leaders scores were not significantly different in extraversion, contentiousness, compassion, responsibility and anxiousness. However, the score for leaders and non-leaders were significantly different in assertiveness. On the differences in a skill, the leaders and non-leaders scores were significantly different in innovativeness/creativity, social management and corporation categories and were not significantly different in self-management category. From these findings, some of the results confirmed while others discarded the hypothesis. Therefore, when hiring, the NGO must consider variables where the hypothesis was confirmed.
