Value Distributions Review

  • Normal is the well-known bell-curve that most people are familiar with and is also referred to as a Gaussian distribution
  • The uniform distribution is where the unique values have almost the same frequency and this is important b/c this might indicate some issue with the data
  • Skewed/unbalanced data distributions as the name indicates are where a smaller subset of values or a single value dominates
  • Bimodal and Poisson but for the scope of this course we will not cover those
