I admit that I am not expert in statistics, but the data they present seem to suggest that the highest scoring test group was in the medium exposure group? Also, something is not right with graph 2?
- shaftway 3y agoI came here because of that. I suspect it's mislabeled, since it looks like it would match the numbers if the labels at the bottom went low, mid, high instead of low, high, mid. But even more than that, I think the numbers demonstrate that some fluoride is better than none. And the low groups average is likely skewed by a single outlier, way at the top of the graph. Poor study all around.
