I don't completely understand what you're asking for, but I can help with the question I believe you're asking. If you're wondering the distance between the two temperatures, it's 6.4 degrees F. This is because -3.2 is 3.2 units from 0, and then you add the highest point in the mean which is 3.2, to get 6.4. In this case, you could just multiply 3.2. I hope this helps, and let me know if you're asking another question. Sorry if this isn't it, and I'll help if it's not what you're looking for! :)
