Metrics

Example: Total Number of Teachers and Students

Add the count of teachers to the count of students.

[Distinct Count: Teacher ID] + [Distinct Count: Student ID]

Example: Rounding the average test score to two decimal places.

...

dim1Total = [Total: Dimension 1 Score];
dim2Total = [Total: Dimension 2 Score];
dim3Total = [Total: Dimension 3 Score];
dim4Total = [Total: Dimension 4 Score];
dim5Total = [Total: Dimension 5 Score];

overallTotal = sum(dim1Total, dim2Total, dim3Total, dim4Total, dim5Total);
overallCount = [Count: Session ID];

round(overallTotal / overallCount, 2)

: Student-Teacher ratio.

The number of students divided by the number of teachers. Distinct counts must be used here if the data contains more than one row per student or teacher.

[Distinct Count: Student ID] / [Distinct Count: Teacher ID]

Use a Comparison to Create a Textual Result

Example: Which scoring dimension had the lowest average score?

Use variables to hold the average of each of the dimensional scores. Use min(...) function to find the lowest dimensional score. Use nested if (cond, trueValue, falseValue) blocks to return which dimension matches the lowest score. Note: If more than one dimension shares the same lowest score, this only returns the first dimension found.

dim1Avg = [Average: Dimension 1 Score];
dim2Avg = [Average: Dimension 2 Score];
dim3Avg = [Average: Dimension 3 Score];
dim4Avg = [Average: Dimension 4 Score];
dim5Avg = [Average: Dimension 5 Score];

lowestScore = min(dim1Avg, dim2Avg, dim3Avg, dim4Avg, dim5Avg);

if (dim1Avg == lowestScore, "Dimension 1",
    if (dim2Avg == lowestScore, "Dimension 2",
        if (dim3Avg == lowestScore, "Dimension 3",
            if (dim4Avg == lowestScore, "Dimension 4",
                if (dim5Avg == lowestScore, "Dimension 5",
                    "Unknown"
                )

The number of students divided by the number of teachers. Distinct counts must be used here if the data contains more than one row per student or teacher.

[Distinct Count: Student ID] / [Distinct Count: Teacher ID]

Example: Determine the proficiency level of the average score.

Compare the average score of the 1st essay submission to what the desired proficiency level (e.g. 4). Then use an if (cond, trueValue, falseValue) block to return the text "Below" if the average score is less than 4, or to return "Above" if the score is equal to or greater than 4.

profLevel = 4;

    "Below",
    "Above"

Example: Indicate whether the proficiency level has "Improved", remained "Unchanged", or "Got Worse" from the first essay submission compared to the most recent.
