Tableau courses and tutorials

Tableau helps turn data into views that support questions and exploration. The data’s granularity and relationships affect every chart. Begin by checking a simple total before building a dashboard whose appearance could hide an incorrect join.

Choose a useful starting point

Check software and version requirements. Tableau Public has sharing implications, so use permitted public data. Look for calculation reasoning, filters, and verification alongside chart construction; a polished layout does not establish accuracy.

Build on the lessons

Create a dashboard answering one question. Reconcile a displayed total with the source, test a filter, and remove a visual that contributes no useful comparison.
