Matrix Totals not making sense

In your matrix visual, it looks like the Total column is displaying the sum of the values in each row, while the Grand Total row is displaying the sum of the values in each column.

To display the average of all the numbers in each row, you can add a new measure to your data model that calculates the average for each row, and then use that measure in your matrix visual.

Here's an example of how to create the measure:

1. Go to the "Modeling" tab in the Power BI Desktop ribbon.
2. Click "New Measure" and give the measure a name, such as "Row Average".
3. In the formula bar, enter the following formula, replacing "Table" and "Value" with the names of your table and value column:

1. Click "Enter" to create the measure.

Once you have created the measure, you can add it to your matrix visual by dragging it from the "Fields" pane to the "Values" area of the visual. You should then see the average value for each row in the Total column of the matrix visual.
