i have made a 3 column table for my garden data collection. The columns are: day, food given, bird seen.
Day is from 1 to 31
Food given is blank if i missed that day, or 1 if i put food out and 2 if i did not
Bird seen is blank if i missed it, 1 if i saw the bird and 2 if i did not.
How can i mathematically see if there is a link between me leaving the food out for the bird and me seeing the birds please?
