(If you missed it, please check out below first) The Hidden Hero of Data Analysis: The Mode (Part 1) : Moving Beyond the "Average Trap" to Read Your "Real Customers" The Hidden Hero of Data Analysis: The Mode (Part 2) Designing Patterns to Capture the Mainstream Using "DAX"   1. Data Introduction and Mode Analysis Plan This article utilizes a hypothetical ice cream sales transaction dataset (Total N=20) to identify the structural truth of customer behavior —the most common choice (the Mode)—which can be easily overlooked by focusing only on the mean. 1.1. Dataset Structure and Description This data consists of 20 hypothetical customer transaction records and includes five key fields. 1.2 Mode Analysis Plan Using Example Data To grasp the 'reality of the majority of customers' hidden behind the mean, we plan to focus the Mode analysis on three key fields of this sample dataset: A. Categorical Data Analysis: Preferred Flavor Goal: Identify the most ...

In Part 1, we confirmed the statistical meaning of the Mode —how it helps us avoid the Average Trap and read the most typical, recurring phenomena in the data.

This part begins with the fundamental question: "Why doesn't Power BI have the MODE function that Excel has?" From there, we will design in detail the three most powerful patterns used in the field, each in its own dedicated section.   1. Why Isn't There a MODE Function in DAX? "In Exce...

The Hidden Hero of Data Analysis: The Mode (Part 1) : Moving Beyond the "Average Trap" to Read Your "Real Customers"

In the world of data analysis, the Mean (Average) is often overrated, and the Mode is frequently undervalued. But the reality of business is driven not by the abstract 'average customer,' but by the 'actual majority of customers' right in front of us. This series is structured into three parts: Part 1 (This Article) : A deep dive into the statistical essence and business value of the Mode. Part 2 (Next Up) : Detailed practical DAX implementation methods for calculating the Mode in Power BI. Part 3 (Following) : A systematic guide to practical DAX implementation and visualization strategies using Power BI, complete with examples. Specifically, we’ll explore the 'structural truth of distribution' that the Mean and Median often conceal, and how this leads to superior strategies for CRM, Sales, and Inventory Optimization.

Power BI DAX Integrated Analysis to Fix the Average Trap (Part 1-3): Segment Efficiency Integrated Analysis: Strategic Decision Report Based on EI-M and EI-R (A Power BI + DAX Approach)

Image
This article provides practical insights utilizing Power BI and DAX to quantitatively assess the management efficiency and structural risk of customer segments, translating directly into strategic decision-making. Our goal is to move beyond simple sales volume and simultaneously understand the typical patterns and stability of customer behavior to optimize resource allocation and marketing strategy. Previous analysis used the Power BI Box & Whisker with Points chart to visualize purchasing behavior across segments and identified stable purchasing groups through the Median and IQR. However, that approach had limits in explaining the structural value and risk of extreme customer groups like VIPs and Regulars.
