Excel formula to check if a range of data are all exactly same

I have a range of cell values. I want to check this range of values and return true if all the values are exactly the same and return false if at least 1 is not the same. ``` Range 1 Confirmed Confirmed Confirmed Result= Confirmed Range 2 Confirmed Negotiation Confirmed Result = Varies ``` ETA: Thanks simoco for the answer which I'm using now. I have a follow-up question. How do I modify this formula to ignore blank cells instead of defaulting to FALSE? With your formula, when it evaluates a range of blank cells (that are waiting for input), it returns "Varies". I want it to return blank instead.
