Dear All, As a medical statistician working in a school for health I find that colleagues frequently ask for help on statistical issues (often of a fairly low level). This is obviously an intrusion and whilst not wishing to appear unhelpful I am trying to come up with some 'rules of engagement' that would enable me to still be approachable and helpful but not overly burdened with inappropriate questions. . I suspect that I am not alone in having this dilemma. I was therefore wondering if anyone has any 'rules of engagement' that they would mind sharing with me? Many thanks, Gordon Taylor
