Link: Probability

Stack data dots to bins, and we get histogram.

  • It can be used to illustrate probability distribution
  • The tricky part is to figure out how wide the bin is
    • Smaller range will be more precise, but too small would not give much informatiaon and makes the distribution too wide

Histogram vs distribution

  • Histogram is discret, while Probability distribution is continous
  • Calculate probability
    • In histogram: add the bars
    • In distribution: use calculus to calculate the area
