--There was no significant difference between the observations and questionnaire answers between the two groups.
++Firstly, the Jarque-Bera test [2] was used to check for normality. When the answers for a question weren't normally distributed, the Mann-Whitney U-Test [3] was used. For normally distributed answers, the T-Test [4] was used. These tests used the null hypothesis that there is no significant difference between the two groups. When the calculated probability value (p-value) is less than 0.05, we can reject the null hypothesis and conclude that there is a significant difference between the two groups for the answers to that question.
