    To apply Benford`s Law, we first need to extract the first digit from each number in our dataset. In Excel, achieve using following formula:

    =LEFT(A1,1)

    Where A1 cell containing numerical value. Drag formula down apply all cells dataset, voila – now first digit each number at fingertips.

    Step 2: Calculating Expected Frequencies

    According to Benford`s Law, the expected frequency of occurrence for each digit can be calculated using the formula:

    =LOG10(1+1/A1)

    Where A1 digit (1 9). By applying this formula for each digit, you can calculate the expected frequencies as per Benford`s Law.
