This worksheet makes extensive use of the ampersand operator (&) to create column A labels dynamically, based on the data values you enter. The ampersand allows the construction of a text value. For example, the cell A10 formula ="P(X<="&B8&")" results in the display of P(X<=7) because the contents of cell B8, 7, is combined with "P(X<=" and ")"
