I have only had basic stats. I conducted some research where I have four different treatments and results for the data range from 0-6. I don't need any elaborate stats test, I just want to know how I should handle the data.
I summed each treatments results and got 162, 72, 75, 14. I turned these numbers into percentages and graphed them. But I am required to put error bars on the graph. So I calculated the standard deviation and when I placed the error bars on the graph, the SD is a negative value for the 5% data value and the data that I tested cannot be a negative value.
I need to report some type of descriptive statistic with this data. I also calculated the mean and for the treatment group with 5% was 0.17. The data value cannot be less than 1 because I'm researching eggs laid on a bean and a beetle can't lay 0.17 eggs.
Thanks you so much for your help!
