Survey Population Paragraph

When looking at the results of my questions I saw that most the results were from seniors (60%), juniors (10%), and sophomores (30%). When asked how flex block could be improved it seemed like some people just wanted to get the short answer done so they wrote a simple answer like nothing or by not existing. I seems that there are some people who don't like flex block and think its pointless.I think my survey could have been made better if there were more questions that could help give ways of changing what id going on during flex block. My survey got a total of 10 kids, the gender of the people who took my survey were 50 percent male and 50 percent female.
