THE LUCK TO HAVE JED AS A TRAINER This intermediate course answered so many questions I had about how to visualize my data. You've developed very easy-to-comprehend tutorials based on real-world examples and provided so many tips and tricks that make calculating fields so much faster. Thank You!! Jed also provides a lot of information on working in the field of data analytics which is a great bonus and provides references for further study in the field of visualizations. When Jed publishes his next set of tutorials – Tableau Desktop for Experts – I'm definitely signing up. Thanks Jed for sharing your knowledge and passion for data
A MUST FOR ALL TABLEAU LEARNERS Still well worth my $$$. Been learning and using Tableau for three years now and Jed still has the clearest, easy to follow and understand lessons – long enough to cover the subject, but short enough to keep it interesting
TABLEAU NOOB I'm coming into this course with absolutely no knowledge or previous experience with Tableau (or data analytics in general). Jed does an amazing job of breaking down these concepts into its most simplistic form. I love it so far and I'm sure you will too. Looking forward to the rest of the Bundle
EXPLANATIONS I CAN UNDERSTAND Thank you Jellyman! You have developed a fun and easy to understand course that simplifies the processes in Tableau, well for me anyway. I've done a few courses to try and comprehend Tableau and this one works for me. Can't wait to learn more in the intermediate course
