In addition to providing descriptive statistics, you should perform some basic statistical procedures to explore any relationships that may exist between variables, especially between your independent and your dependent variables. Think of your demographic variables as the independent variables. If you treat your Likert Scale responses as linear numeric, then you can calculate means for your scales and then compare these means across the series of questions you asked. For example, the last statement seems to have received low ratings. You may want to see if gender could explain the difference in ratings.
Mean ratings are statistically significantly different by gender.
Looks like the men in your audience didn't like the explanations. You may want to think about revising the explanations. And, you should be cautious when interpreting the mean for the graphics statement. It could be that the 20 who didn't like the graphics just didn't respond. All rights reserved.
