How to calculate probability density function?

The Excel NORMDIST function calculates the Normal Probability Density Function or the Cumulative Normal Distribution but are you sure your data fit normal distribution? So you should find the best distribution function for your data and then calculate CDF or PDF for your data. You can use the Data-Tool (Excel add-ins) to find the best distribution for your data and then use this distribution for drawing CDF Graph or PDF Graph.

Follow the below videos to know about the process and visit the Data-Tool Page:
