Median Finder | Access Add-in


In step 1, you select the table from which to get your median value.

_______________

In step 2, you select the column from which to get your median value. The column must be a numeric column.

_______________

Your table has 18 records of nulls, zeros, positive or negative values. We include all possible entries to demonstrate how you can choose to deal with them (see the log table at the bottom).

_______________

In the third and final step, you have one or more options to choose from. You can choose to go without any criteria in which case you get what you see. Note that you chose to create/make a log table/entry for your reference later on without having to run the wizard again.

_______________


Here you chose one criteria. Notice that the other two options were disabled, because they are mutually excluded.

_______________

Here you exclude nulls from your calculation, which is what Access does for its aggregate calculations. That’s why we made this option your default selection.

_______________


Here again the other two choices were disabled for the same reason mentioned above.

_______________


You now use a combination of three options. You first substitute zero values for nulls, eliminate any duplicate values, and then exclude the top 20 % before proceeding to get the median and average values. You can choose one of several different combinations like this one.
