Inserting Row without changing reference cell on another sheet

I am trying to create a formula that references information on two different sheets, but i want it to show me the values that are newly created when a new row is inserted. The two current sheets are Master and Data.

I have a formula on Master that reads ='Data'!$K$3 to reference the value on Sheet data in cell K3. When a new row is inserted showing me the current readings, I want the Master sheet to show me the NEW value in cell K3 on the data sheet. The problem is, the insert of a row moves the formula on the Master sheet to now be ='Data'!$K$4. How can i STOP the insertion of a row from changing the formula so i continue to see the value i need?

Thanks for your assistance.
