      GREAT class for the analyst who isn't, and never will be, a statistician. I learned so much in such a short time and have already had the opportunity to apply what I learned. Thanks for taking the complex math out of statistics and putting it into English for me.

      The instructor of the training course has made the complicated statistical theory a lot easy to understand and follow, I also find the course materials can be immediately applied on the real world cases.

      It was very educational to learn the stat stools available on Excel. The instructor was able to use real world and job specific examples to make the various statistical options more relevant.

      I found the course very informative in that it put the whole theory of stats into a program that I could understand and make sense of. Natalie did an excellent job of explaining things using situations that applied to our business. I would recommend this course to anyone wanting to learn how to use stats to analyse data.

      This course was a great refresher in statistics for me. The presentation and organization of the course material allowed for a good understanding of the components useful to a food production company. I now can write better experiments, use descriptive and inferential statistics effectively and have more confidence reporting results and making conclusions.
      I would highly recomend this course to anyone who wants to add more power to their project results and recommendations.
