To calculate the average duration of Megan's transactions that took less than 5 minutes, you can use the AVERAGEIF function in Excel. Here's how you can do it step by step:
1. First, make sure you have a column in your Excel spreadsheet that contains the durations of Megan's transactions.
2. Select an empty cell where you want to display the average.
3. Enter the following formula in that cell:
=AVERAGEIF(range, "<"&TIME(0,5,0))
Replace "range" with the range of cells that contain the durations of Megan's transactions. For example, if the durations are in column A from row 2 to 100, you would use "A2:A100" as the range.
4. Press Enter to get the average.
This formula uses the AVERAGEIF function to calculate the average of a range based on a specified criteria. In this case, the criteria is "<"&TIME(0,5,0), which means less than 5 minutes.
The TIME(0,5,0) function is used to represent 5 minutes in Excel's time format. The "<" symbol is used to specify the condition of less than.
The AVERAGEIF function will calculate the average of the durations that meet the specified criteria and display it in the selected cell.
Make sure to adjust the range and criteria according to your specific data.
