Yоu cоnduct аn experiment tо test if wаter temperаture affects developmental time of dragonfly nymphs. You only had time to set up three replicates for each of three temperature treatments: 10, 13, and 15 degrees Celsius. Each replicate is one individual nymph. Therefore, you have data on the developmental rate of three nymphs at each temperature treatment. The data show some variation within each treatment. You conduct your statistical test and your resulting p-value is 0.85. These results indicate the result was not significant. However, you can interpret this result another way, which is:
