I have here a data-set containing river flow rates for two separate river catchments, A and B.
There are exactly 365 values for river flow rate for both A and B.
Therefore, am I correct in assuming that each value is for each day of the year (there are 365 days in a year).
Therefore, am I working with three variables here?
- Day (range from 1 to 365)
- Flow rate for river A
- Flow rate for river B
In order to test for significance, should I use an independent sample t-test to compare both means?
