user: As a data analyst, I've been tracking the daily temperatures in a particular city over the last month. The temperatures I've logged range from 22 to 80 degrees Celsius, changing by 2 degrees each day. I need to calculate the average monthly temperature from this data set to understand the climate trend better. Can you help me with this?
