Temperature and Precipitation-Is There a Connection

Project #1319 on iSENSEProject.org

Often times people will discuss weather in a casual manner.  Terms such as "nice weather today" or "will this storm ever stop" is commonplace language when discussing weather. I have also heard often times about torrential rainfall that can occur during summer storms.  But does temperature really have and impact on precipitation?  In this set of data, I will display Methuen MA average temperatures to it's average precipitation to see if indeed this cities climate if two variables are connected.

Guided Questions:

Do Temperature and Precipitation have a direct relationship?

Is the relationship  very strong, strong, somewhat strong, somewhat weak, weak, or very weak?

Which style of data best supports your opinion?
