Is the Improving data quality in data analytics & machine learning Coupon Worth It?

Expert review by Josh Smith, Lead Course Reviewer at CourseSpeakUpdated Nov 6, 2026

The short answer is yes — provided the Development skills this course teaches actually line up with what you want to build. The regular price for Improving data quality in data analytics & machine learning on Udemy is $149.99. The coupon code listed on this page drops that to $9.99 — a saving of $140.00, or 93% off the standard rate. Spread across 5h 22m of on-demand video, that works out to roughly $1.86 per hour of content — less than the cost of a single chapter of most printed development textbooks.

A discount is only worth something if the material delivers, and the curriculum here is built around practical outcomes. Mike X Cohen walks you through strategies for increasing data quality, ways to assess data quality, and interpreting data visualizations — concrete skills you can apply, not abstract theory. It has already been taken by 5,729 students and holds a 4.5-star average from verified reviews, which is a reasonable sign the content holds up in practice.

The prerequisites are worth reading before you commit: Interest in working with data; Interest in knowing more about data quality. This one suits learners who already have some grounding in Development. In practical terms, expect around 5h 22m of on-demand video to work through at your own pace. The material is presented in English.
