If you prefer a more granular approach to calculating the mean, you can use the SUM and COUNT functions in combination. Here’s how:

1. **Select the Cell:** Click on the cell where you want to display the mean value.2. **Type the Formulas:** Enter the formula “=SUM(range)/COUNT(range)” without the quotes, where “range” is the range of cells containing your data values. For example, if your data values are in cells A1 to A10, the formula would be “=SUM(A1:A10)/COUNT(A1:A10)”. Press Enter to calculate the mean. The cell will now display the mean value.

### Accounting for Missing or Blank Cells in Mean Calculation

Dealing with missing or blank cells in your data set is essential to ensure an accurate mean calculation. Here are two methods to handle missing or blank cells:

1. **Exclude Missing/Blank Cells:** If you want to exclude missing or blank cells from the mean calculation, you can use the AVERAGE function in combination with the IF function. Here’s how:

1. **Select the Cell:** Click on the cell where you want to display the mean value.2. **Type the Formula:** Enter the formula “=AVERAGE(IF(ISNUMBER(range), range))” without the quotes, where “range” is the range of cells containing your data values. For example, if your data values are in cells A1 to A10, the formula would be “=AVERAGE(IF(ISNUMBER(A1:A10), A1:A10))”. Instead of pressing Enter, press Ctrl+Shift+Enter to indicate that it is an array formula. The cell will now display the mean value, excluding the missing or blank cells.

2. **Assign a Placeholder Value:** If you want to assign a placeholder value, such as zero, to the missing or blank cells before calculating the mean, you can use the IF and ISBLANK functions. Here’s how:

1. **Select the Cell:** Click on the cell where you want to display the mean value.2. **Type the Formula:** Enter the formula “=AVERAGE(IF(ISBLANK(range), placeholder, range))” without the quotes, where “range” is the range of cells containing your data values, and “placeholder” is the value you want to assign to the missing or blank cells. For example, if your data values are in cells A1 to A10 and you want to assign zero as the placeholder value, the formula would be “=AVERAGE(IF(ISBLANK(A1:A10), 0, A1:A10))”. Instead of pressing Enter, press Ctrl+Shift+Enter to indicate that it is an array formula. The cell will now display the mean value, with the missing or blank cells assigned the placeholder value.

### Adjusting Decimal Places for Mean Accuracy
