Need Formula to Place Indicator After Comparing Two Columns

Fam ID Has Doctor? Split Family?
119501322 Yes

548824945 No
550817217 No
238652523 No

I'm trying to figure out a formula that would return "Yes", or some other indicator, in the "Split Family?" column if rows with the same Family ID have different entries in the "Has Doctor" column. For instance, rows 2, 3, and 4 in the above example would return "Yes". I'm not sure where to start with this or if a formula is more appropriate vs code. Any help would be appreciated.

That seems to do what I need it to! Thank you!
