When it comes to analyzing business data, managers are always asking, “so how many distinct x each y is doing?”
And that sends us, data analysts & reporting professionals running from pillar to post figuring out the best way to do it.
- We can use variations of SUMPRODUCT, COUNTIFS etc, but the methods are not flexible..
- We can use VBA, but it would become slow as you add more data.
- We can use Pivot tables, but it only gives half of what we want ie each y part, but not distinct count of x.
- We might as well shave our head with a shovel before manually counting values.
And that brings us to 2 distinctly simple solutions:
- Using Power Pivot & Excel 2010
- Using regular pivot tables in Excel 2013
Today, lets talk about these 2 approaches & see why they are so better than anything else for distinct count situations.Continue »

What is Power Pivot course?
These days almost any job requires data analysis & presentation of results.

Having these vital skills can make you invaluable to your organization & expose you to new opportunities. Not to mention the amount of time, money & effort you can save by efficiently using Excel.

Details about Power Pivot Course
Power Pivot, an Excel add-in makes it easy to connect, analyze & visualize massive amounts of data. This course aims to teach you how to use Power Pivot to analyze data, create advanced reports & prepare dashboards all from familiar interface of Excel. This is ideal for data analysts, reporting & MIS professionals, business analysts, managers & dashboard makers.
A measure is a formula for the values area of Power Pivot table.
A measure can be implicit or explicit.
Implicit measures are created automatically when you drag and drop a field in to Power Pivot values area. For example, in last week’s introduction, we created an implicit measure for SUM of Sales by dragging and dropping the sales amount field in to values area of our power pivot table.
Explicit measures are created by you using New measure button in Power Pivot tab (or Calculated Field button in Excel 2013 Power Pivot tab). You can also create a measure in the Power Pivot window.
Learn what measures are, how to create them using DAX (Data Analysis Expression) formulas in this video tutorial.Continue »
