Visualizing Data Distribution in Power BI – Histogram and Norm Curve -Part 2

Posted on by Leila Etaati

In the Part 1 I have explained some of the main statistics measure such as Minimum, Maximum, Median, Mean, First Quantile, and Third Quantile. Also, I have show how to draw them in Power BI, using R codes. (we have Boxplot as a custom visual in power BI see :https://powerbi.microsoft.com/en-us/blog/visual-awesomeness-unlocked-box-and-whisker-plots/ ). However, to see the data Read more about Visualizing Data Distribution in Power BI – Histogram and Norm Curve -Part 2[…]

Visualizing numeric variables in Power BI – boxplots -Part 1

Posted on by Leila Etaati

In this post and next one, I am going to show how to see data distribution using some visuals like histogram, boxplot and normal distribution chart. It always important to have a holistic perspective regarding the minimum, maximum, middle, outliers of our data in one picture. One of the chart that helps us to have a Read more about Visualizing numeric variables in Power BI – boxplots -Part 1[…]
