Yes, it is possible to find the second most common value in a group of numbers in Excel. Here's how you can do it:

1. First, select the range of cells that contains the numbers you want to analyze.
2. Next, go to the "Formulas" tab in the ribbon and click on "More Functions" "Statistical" "FREQUENCY".
3. In the "FREQUENCY" dialog box, select the range of cells that contains the numbers you want to analyze as the "Data_array".
4. Then, select an empty range of cells where you want to display the frequency distribution as the "Bins_array". You can do this by clicking on the range selector button next to the "Bins_array" field and then selecting the range of cells.
5. Make sure that the "Array" option is checked and click "OK".
6. Excel will now display the frequency distribution in the range of cells you selected in step 4. The first column will show the values in the range, and the second column will show the frequency of each value.
7. To find the second most common value, simply look for the value with the second highest frequency in the frequency distribution. You can do this manually by scanning the second column, or you can use the "LARGE" function to automate the process. For example, if the frequency distribution is in cells A1:B10, you can use the following formula to find the second most common value:
   Formula:

   =LARGE(B1:B10,2) 


This formula will return the second largest value in the range B1:B10, which corresponds to the second most common value in the original range of cells. You can adjust the range references in the formula to match your specific data.
