          ----------------------------------------

Answer 1

I could be not understanding...but the way I did this was to also select DISTINCT then select the average columns values I needed. Like this:

SELECT DISTINCT contributing_factor_vehicle_1, AVG(number_of_cyclist_injured) FROM "table1".motor_vehicle_collisions_crashes 
GROUP BY contributing_factor_vehicle_1
ORDER BY avg(number_of_cyclist_injured) desc

That's what created something like so:

This was NYC motor vehicle crash data btw.
