Before we dive into using the PERCENTILE.INC function, it’s important to understand what percentiles are and how they work. A percentile is a measure used in statistics to indicate the value below which a given percentage of observations in a group of observations falls. For example, the 90th percentile is the value below which 90% of the observations may be found.
The PERCENTILE.INC function in Power BI is designed to calculate the nth percentile of a set of values. For example, if you’re looking to calculate the 90th percentile, you would use the formula =PERCENTILE.INC(values,0.9), where “values” is the range of values you’re analyzing.
Using the PERCENTILE.INC Function in Power BI
Now that we’ve covered the basics of percentiles, let’s take a closer look at how to use the PERCENTILE.INC function in Power BI. Here are the steps you’ll need to follow:
1. Start by opening Power BI and selecting the “Insert” tab.
2. From there, select the “New Measure” option.
3. In the formula bar, enter the following formula: =PERCENTILE.INC(values,percentile), where “values” is the range of values you’re analyzing and “percentile” is the specific percentile you want to calculate.
4. Be sure to format the measure as a percentage, so it’s easier to read and understand.
5. Now, you can add the measure to a visual in your report to see the percentile distribution of your data.
Tips and Tricks for Using the PERCENTILE.INC Function
While the PERCENTILE.INC function is relatively straightforward to use, there are a few tips and tricks you can use to get the most out of it. Here are a few things to keep in mind:
– Be sure to choose the right percentile value for your analysis. Depending on the distribution of your data, you may want to calculate the 90th percentile, the 95th percentile, or another value.
– Consider using the PERCENTILE.EXC function in some cases. This function calculates the exclusive nth percentile of a set of values, which can be more appropriate in some situations.
– Use the PERCENTILE.INC function in conjunction with other DAX functions to gain deeper insights into your data. For example, you might use the function to calculate the percentile distribution of a specific product line, then use the AVERAGE or MEDIAN function to calculate the average or median value of that product line.
Overall, the PERCENTILE.INC function is a powerful tool for analyzing data in Power BI. By using this function, you can gain a deeper understanding of the distribution of your data, which can help you make more informed decisions. So, the next time you’re working with data in Power BI, be sure to give the PERCENTILE.INC function a try.
