Data Analytics Guide

Module 4

Summary

The video eight common mistakes that individuals and organizations make when engaging with data analytics: Lacking an Objective, Insufficient Data, Mistaking Correlation for Causation, Mistaking Statistical Significance for Business Significance, Ignoring Outliers, Improper Tool and Methods Selection, and Drawing Conclusions Prematurely. Avoiding these errors is crucial for achieving accurate and impactful results. Beyond specific mistakes, analytics operates within three types of broader limitations: practical, legal, and ethical. Recognizing these is fundamental to being "fully conversant in analytics." The field of analytics ethics is "new and evolving," and organizations should "play it safe" by validating approaches to ensure they are not only legal and ethical but also "that customers will find them acceptable."
