Excel provides built-in tools to help you to find discrepancies like Filters, Conditional Formatting, advanced functions (If and IS, VLookUp, etc.), and Add-ins.

Averaging in Microsoft Excel is easy, until you start excluding specific values. Here are three ways to average a data set when giving special consideration to the highest and lowest values.

Filters are great tools, but you can't remove specific items from the results. When you need to do this, try Find All in Excel instead.
