Given the initial information I suspected that he would find that only group 5 is significantly different from the overall average, a result I'd consider intuitive, reportable and useable in the context of the problem. I'm not classically trained as a statistician, so I'm here to learn - what would you suggest? | |

Suppose people's height is a control: would you recommend dividing height into bins and then letting the bins be distinct levels of a factor variable? | |
