When I try to put the values of my dictionary into the SciPy f_oneway function it gives me an error saying that input is too short (must be greater than 1), but the length of it is 3 so it should be fine. I know I can just input the values individually separated by commas using the key, but I want this to work for unknown keys/dictionary lengths. Is there something specific I have to do or am I going about this completely wrong?
