Insights: Average Completed Activities Per Learner Per Day

The Average Completed Activities Per Learner Per Day metric provides insight into how consistently learners complete activities on the days they practice. This measure ensures that each learner is treated equally, regardless of how often they practice.

How the Average is Calculated

The calculation is done in two steps.

Step 1: Calculate each learner’s personal daily average

• Review one learner at a time.

• Add up all activities they completed across the days they practiced.

• Count only the days they were active (ignore days with no activity).

• Divide their total activities by the number of practice days.

Example:

• Learner A completed 12 activities over 3 practice days → 12 ÷ 3 = 4 activities per day.

• Learner B completed 5 activities on 1 practice day → 5 ÷ 1 = 5 activities per day.

Step 2: Average across all learners

• Add all learners’ personal daily averages together.

• Divide by the total number of learners.

Example (continuing from above):
(4 + 5) ÷ 2 learners = 4.5 activities per learner per day.

Example from a Dataset

In one dataset:

• 19 learners practiced during the selected period.

• Applying the formula gives an average of 5.78 activities per learner per day (rounded to two decimals).

• Individual learner averages ranged from 1 activity per day to as high as 30.

Why the Formula Differs from the Total Number of Activities

The total number of activities completed (for example, 427 across all learners) does not directly match the calculated average.

This is because learners practice on different numbers of days:

• Some learners practice only once or twice but complete many activities on those days, giving them a high personal average.

• Others practice more frequently but complete fewer activities per day, resulting in a lower personal average.

When calculating this metric, every learner is weighted equally. This prevents highly active learners from disproportionately influencing the result.

Comparison:

• Weighted average (total activities ÷ total practice days) = 427 ÷ 29 = 14.72.

• Average per learner (equal weight for each learner) = 5.78.

Key Takeaway

The Average Completed Activities Per Learner Per Day reflects how many activities a typical learner completes on the days they practice. This method ensures fair representation across all learners, regardless of individual practice frequency
