Hello,
I have a dataset containing observations over the course of 3 years. How can I calculate the average number of observations by month? So, for instance, I have a number of observations from January 2015, 2016, and 2017. How can I calculate the 3-year average value of observations that occurred in January (and every other month)?
I hope to end up with average as a separate value that I can plot on a bar chart.
A small sample of my dataset is attached. I am basing all of my date calculations on DtSpec2.
Thanks!
