Refresh the pivot in sheet ‘Pivot & Formulas to Verify’ to see the variation. The randomly generated ‘State’ data in column C (sheet ‘Randomly Created Data’) is updated. Randomly add or subtract a percent of each state’s population. Option 3 manually type in a positive/negative number (added/subtracted to state population) Option 2 typing in a % value in cell F3 increases/decreases (random) the individual state population

Option 1 smallest variation if we’ve dragged formulas far enough in sheet ‘Randomly Created Data’

I want to add variation manually (using columns H & I).

Currently set to 30.0% Based on value in cell F3

Use original expanding range (smallest variation).

I have extended our solution to give us these three options: After all, isn’t it supposed to be random?įasten your seat belts ladies and gentlemen. What if you want more variation in your random data. Sheet ‘Pivot & Formulas to Verify’ shows how close our randomly generated data is to our original state population data. If you don’t drag the formulas down very far you’ll see more variation. Steps 2, 3, and 4 are dragged down as far as you want in sheet ‘Randomly Created Data’. Drag it down further if you have more data. Step 1 runs alongside your original data. Here is my Excel file (or get it here from my OneDrive). We bin using TRUE (approximate match).Īdd this formula =INDEX(‘Original Data’!$A$6:$A$55,B6)Index function references our ‘State’ values using the match function result (Step 3) to display a state. Add this formula in cell C6 =B6+C5 alongside the data.Īdd this formula =RANDBETWEEN(1,’Original Data’!$D$5)that creates random numbers between 51069 (total sum of the population).Īdd this formula =MATCH(A6,’Original Data’!$C$5:$C$55,TRUE) that bins our random number back into our expanding sum. Our original data: ‘ State‘ and ‘ Population‘. STEP 1 EXPANDING SUM FORMULA (Cumulative Sum) Let’s use population by state for the United States. See how we can automate this with just four easy steps! What if you want to create random data that favors some values over others? People have told me that they copy and paste or manually drag the values to repeat them. We can create random data using RANDBETWEEN and INDEX functions.
