What statistics test would you use to test the relationship between the cell size (measured in a ratio of surface area and volume) and the rate of diffusion (measured in the distance travelled by a substance over time). Amit Mishra - NES International School Mumbai 30
Correlation Tests Relationships between measured values/ numerical values/ quanitative Positive correlation– as one value increase so does the other. Negative correlation – as one value decreases the other increases. No Relationship – no pattern. Amit Mishra - NES International School Mumbai 31
