when creating an input/Output table where do you enter the formula

1 answer

In Excel or similar spreadsheet applications, when creating an Input/Output (I/O) table, the formula is typically entered in the cell corresponding to the output value for a specific set of input values. Here's how you can set it up step by step:

  1. Define Inputs and Outputs:

    • Determine the variable inputs that will change and the output that will be calculated based on those inputs.

  2. Create the Table Structure:

    • In the first column, list the different input values you want to test.
    • In the subsequent columns, set up headings for the outputs you want to calculate based on those inputs.

  3. Enter the Formula:

    • In the cell of the output column corresponding to the first input value, enter the formula that relates the input to the output. This formula should reference the input cell.

    For example, if your input values are in column A and you want to calculate the output in column B using a formula that doubles the input, you would enter =A1*2 in cell B1.

  4. Fill Down the Formula:

    • If you have multiple input values in column A, you can drag the fill handle (a small square at the bottom-right corner of the cell) down the output column to apply the formula to the other cells based on their corresponding input values.

  5. Using Data Tables:

    • If you’re setting up a more advanced I/O table (like a Data Table in Excel), you can do this by:
      • Selecting the range of your input values.
      • Going to the Data tab, selecting ‘What-If Analysis’, and then choosing ‘Data Table’.
      • Specify the Row input cell and/or the Column input cell according to where your input values are located.

Following these steps will allow you to create a functional Input/Output table where the outputs are calculated based on the inputs you provide.
