You can use the following basic syntax to calculate the mean, median, sum, standard deviation, etc. in Excel while ignoring #N/A values:

=AVERAGE(IFNA(A2:A21, "")) =MEDIAN(IFNA(A2:A21, "")) =SUM(IFNA(A2:A21, "")) =STDEV(IFNA(A2:A21, ""))

This syntax simply replaces #N/A values with blanks and then calculates the descriptive statistic youâ€™re interested in.

The following examples show how to use this syntax in practice.

**Example 1: Calculate Mean & Ignore #N/A Values**

The following screenshot shows how to calculate the mean of a dataset that contains #N/A values:

**Example 2: ****Calculate Median & Ignore #N/A Values**

The following screenshot shows how to calculate the median of a dataset that contains #N/A values:

The median of the dataset (ignoring all #N/A values) is **14**.

**Example 3: ****Calculate Sum & Ignore #N/A Values**

The following screenshot shows how to calculate the sum of a dataset that contains #N/A values:

The sum of the dataset (ignoring all #N/A values) is **251**.

**Example 4: ****Calculate Standard Deviation & Ignore #N/A Values**

The following screenshot shows how to calculate the standard deviation of a dataset that contains #N/A values:

The standard deviation of the dataset (ignoring all #N/A values) is **6**.
