Use the following information for questions:
Spatial perception is measured on a scale from 0 to 10. Two groups of 8^th grade children are tested for spatial perception. The students in group 1 were first given a short course on spatial concepts. The students in group 2 received no such instruction. SPSS was used to calculate descriptive statistics for the two samples.
-What do we know about the p-value if we wish to test if participation in the course results in significantly higher spatial perception scores?

B) 0.01 < p-value < 0.025 
C) 0.025 < p-value < 0.05 
D) p-value > 0.05

Quizplus · Accepted Answer

A p-value < 0.01 indicates strong evidence against the null hypothesis, suggesting that participation in the course significantly increases spatial perception scores.
