q2 i? Fifth-grade mathematics showed opposing trends on the two tests, with ITBS declining and ISAT rising significantly; ISAT mathematics trends rose in all three grades. → Easton 2003

q2 · i? · associational · r2

The same standardized citywide trend analysis for fifth-grade mathematics found diverging test trends; the article calls the difference between the opposing trends statistically significant. The authors add that since 2001 and 2002 scores on both tests move in the same direction, the anomaly may not be of much concern.

"In fifth grade, ITBS scores declined and ISAT scores rose. The difference between these opposing trends is statistically significant."
