Why Attend this Course?

  • Many analysts start their analysis by opening EXCEL. 
  • There is a process that should be followed for data analytics projects.  This will be introduced and utilized during class.
  • Decisions are made based on the analysis without knowing how the underlying data looks.
  • Exploratory data analysis emphasizes ‘knowing the data’ as a precursor to decision-making.  This course will introduce an organized and structured approach to looking at variable distributions, missing data, outliers and other typical data issues.
  • A common mis-conception is that more data is better.  The truth is better data is better.  Technology allows us to create models more easily and quickly than in the past which is often an impetus to ‘just add more variables’.
  • Continuing with the line of organized and structured, this course will present techniques to determine the relationships among explanatory variables and assess the relationships between explanatory and outcome variables.

What Makes this Course Stand Apart?

  • An emphasis on utilizing the abundance of data in an organized, structured and well thought out manner.
  • A strong focus utilizing data visualization techniques that highlight the unexpected.
  • A case study approach using real world data.
