Regression Through Spreadsheets

City temperatures (using Cities.csv)
1.	temperature (y) versus latitude (x)
2.	temperature (y) versus longitude (x)
3.	longitude (y) versus temperature (x)

Regression Through Spreadsheets (2) 
1.	temperature versus latitude: =correl(c:c,e:e)
2.	temperature versus longitude: =correl(d:d,e:e)
3.	temperature versus temperature: =correl(e:e,e:e)
4.	First two temperatures versus first two latitudes: =correl(c2:c3,e2:e3), also show scatterplot
5.	First two longitudes versus first two latitudes: =correl(c2:c3,d2:d3)
