for the ANOVA i need to run the Post Hoc Tukey test to determine which groups are different and by how much. for example for total discharge it is showing that there is a significant difference amongs age groups and so i need to determine which pair of age groups are different and what is the difference in their total discharges. similarly for those that are significant in both LOS and total chargethe age groups should be more like – 1 to 20, 21 to 40, 41 to 60 and so on. But choose the groupings that make sense in your data – if you believe that 30 to 45 is more prone to get a gastrectomy then choose groups like 1 to 14, 15 to 29, 30 to 44, 45 to 60 and so on so that you can make out some significant differences if any. total discharge, total charges and LOS should definitely be an outcome for the ANOVA across age groups (the way i grouped them above), race, gender and pay1 in SPSS .can you do it and provide my with the documents and how it appear and the interpretation???
