1. Click on cell B3 in your Excel spreadsheet.

5. Click on cell C3 and repeat steps 2-4, but change the formula to =AVERAGE(C2:C31). This calculates the average for the second town.

6. Repeat the process for cell D3 with the formula =AVERAGE(D2:D31). This calculates the average for the third town.

Now, cells B3, C3, and D3 should display the average hours of sunshine for January for each town, rounded to one decimal place.
