Using a scatter diagram with x(age in weeks) of calves and y (weight in kg) and the info is as follows
Week 1 /42kgs
Week 3 /50 kgs
Week 10/75 kgs
Week 16/100kgs
Week 26/150kgs
week 36/200kgs
would you estimate the linear correlation coefficient R to be positive , close to zero, or negative?
I say it would be positive but I am then unsure what formula is how I compute the sample correlation coefficient r?
