8 Best Data Preparation Courses for Beginners

We compared 8 Data Preparation courses currently listed on Coursera, Udemy and edX, priced from $19.99 to $129.99. 1 comes from a named university or institution, including University of Minnesota. They are ordered by our CourseAsk score, which is built from how thoroughly each course describes what it teaches, whether it comes from a named institution, and how it compares on price — not from star ratings, which our course data does not include.

How these 8 courses were chosen

Every course below is a real, currently listed course from Coursera, Udemy, edX, matched to "data preparation" by our catalog and ordered by our CourseAsk score. Courses whose own title names the topic rank above those only tagged with it.

The grade on each entry scores how much the provider publishes about the course before you pay — the length and detail of the description, whether it lists learning outcomes and objectives — and whether a named university or institution stands behind it. A is fully documented and institution-backed; E is little more than a title and a price. Courses with almost nothing published are left ungraded rather than marked down, because an unknown course and a poor one are not the same thing.

There are no star ratings on this page — the course feeds we license do not include them, and we would rather leave a column out than fill it with a number we cannot stand behind. What we do have is price: these range from $19.99 to $129.99, as listed by the provider when we last updated the page.

Best Data Preparation Courses for Beginners compared

Prices shown are the provider's listed price when we last updated this page. Confirm on their site before enrolling.

What the prices here tell you

The 8 priced courses on this page run from $19.99 to $129.99, with the middle of the range around $49.00 — a spread of $110.00. That is a wide gap for one subject. A higher price on this page usually reflects who is behind the course rather than how much material it contains, so it is worth opening two or three at different price points and comparing their syllabus before deciding.

Who is behind these courses

These courses come from Coursera, Udemy and edX. The platforms differ in how they sell: some charge once per course, others expect a subscription, and the listed price is not always what you pay at checkout after a promotion. 1 of these are produced by a named university or institution, including University of Minnesota — which usually means a fixed syllabus and a recognised certificate, rather than an individual instructor’s own course.

Before you enrol

Open the provider’s own page and check three things this comparison cannot tell you: when the course was last updated, what the syllabus actually covers in its later sections, and what recent learners say. Prices shown here are the provider’s listed price when we last rebuilt this page on 30 August 2026 — they change often, and a promotion can move them substantially. We earn a commission if you enrol through our links, which costs you nothing and never affects the order courses appear in.
