Hi Harry,

Yes, there is a formula to average your blood pressure readings in one column. Here are the steps:

1. First, select the cell where you want to display the average.
2. Then, type the formula "=AVERAGE(A1:A4)" (without the quotes), assuming that your blood pressure readings are in cells A1 to A4.
3. Press Enter and the average of your blood pressure readings will be displayed in the selected cell.

That's it! The formula will automatically calculate the average of all the readings in the specified range. You can also adjust the range of cells to include more or fewer readings as needed.
