Running average

Use the Running average tool to calculate a running average for a column. Adds a new column that returns the running average of the value columns you specify. Use when you want to calculate a running average for a column.

For example, you want to find a particular occurrence of a specific attribute. First, add a count. Use the Formula tool to add a value of "1" to each record in your dataset. This step helps to track each entry. Next, rank your data. Apply the Running Total tool and group your data by the attributes that you want to sort. This helps you rank the entries in either ascending or descending order, based on your chosen attribute. Finally, refine your data. After you rank your data, you have two options: one is to use the Formula tool again and apply a Min/Max formula to pinpoint the exact occurrence. The second one is to use the Filter tool to zero in on the specific running total value that you're seeking.

Group by is an optional configuration.
