Question

1. An ANOVA test was conducted to see whether bike frame type A,B, or C had effect on speed over a one mile distance. When collecting data, the researcher measured the time(in seconds) it took the bikes to travel one mile. Test results warranted post-hoc procedures. The turkey HSD approach was used with the following results:

Which pair of bike frames are significantly different?

Group comparison 98.33% confidence interval TypeA-Type B (-12.70,-4.29) Type A- Type C (-19.63,-8.87) Type B- Type C (-9.89,1.61)

Explanation / Answer

Group comparison

98.33% confidence interval

TypeA-Type B

(-12.70,-4.29)

Type A- Type C

(-19.63,-8.87)

Type B- Type C

(-9.89,1.61)

Which pair of bike frames are significantly different?

TypeA-Type B frames are significantly different. ( 0 value not in the interval).

TypeA-Type C frames are significantly different. ( 0 value not in the interval).

TypeB-Type C frames are not significantly different. ( o value in the interval).
