The file P18_06.xlsx contains monthly data from 1920 to 2004 on average temperatures in the 48 contiguous states and several regions of the U.S. (The codes for locations are listed on the Locations sheet.) Rearrange the data so that there is a Month column (with values such as Jun-1945) and a column for each state or region (spelled out, such as Virginia or Southeast). Each state or region column should contain its monthly temperatures. Then create a time series graph for a few states or regions?
