Direction of Motion vs. Number of kMts on Individual Kinetochores

		P*		AP‡
Average§		21.0		24.9
Standard deviation		3.1		2.7
n		9		7

^* Includes kinetochores in transition from AP to P.  

^‡ Includes kinetochores in transition from P to AP.  

^§ Difference in kMt numbers for P and AP kinetochores is statistically significant: P = 0.028 for two-tailed t test.
