Thanks Donald and Karl for your responses... Yeah, I don't know why I didn't think to compute my eta-squared on the significant trends. As I said, trend analysis is new to me (psych grad student) and I just got startled by the results. The "significant" 4th and 5th order trends only account for

Trend analysis question

2001-03-03 Thread Philip Cozzolino
Hi, I have a question on how to interpret a specific trend analysis summary table. The IV has 6 levels, so I had SPSS run the analysis checking up the 5th order trend. There is a significant linear and quadratic trend, but not cubic. However, after the cubic non-significant finding, the 4th a
