Measures are how you display data from your xAPI statements in reports. They are typically numbers that are aggregated and displayed in Watershed’s graphs and charts, but they can output text in certain situations.

# Default Measures

When creating or editing reports in Watershed's report builder, many report types provide measure options that can be used immediately:

1. ** Activity Count** is the number of different activities contained within a grouping.

**Example**: If you’ve organized your Correlation Report by person, using the Unique Activity ID Count measure would show the number of different activities each of your people have performed. If you’ve organized your Correlation Report by Activity Type, using the Unique Activity ID Count measure would show the number of activities that have been performed for each type.

2. * Average Score* is the average of all scores recorded across all activities in a grouping.

**Example**: If you’ve organized your Correlation Report by Week, using the Average Score measure would show you the average of all of the scores across all activities for each week. If you’ve organized your Correlation Report by Person, using the Average Score measure would show the average score across all activities for each person.

3. * Total Time *is the total amount of time people have spent performing all activities in a grouping.

**Example**: If you’ve organized your Correlation Report by Person, using the Total Time measure would show the amount of time each person has spent on all activities. If you’ve organized your Correlation Report by Activity, using the Total Time measure would show how much time has been spent on each Activity.

4. * Completion Count* is the total number of times activities have been completed in a grouping.

**Example**: If you’ve organized your Correlation Report by Person, using the Completion Count measure would show how many activities each person has completed. If you’ve organized your Correlation Report by Activity, using the Completion Count measure would show how many times each activity has been completed.

5. * Interaction Count * is the number of statements for the selections you have made within the measure.

**Example**: If you were setting up a Leaderboard Report and chose to organize by person and chose Interaction Count, Leaderboard Report would show total number of statement for that person.
