Continuous random variables have an inifinite number of values for any given interval. While similar, the approach to analysis is very different from discrete variables

  • Summation becomes integration
  • Probability becomes area under a curve

The probability density function (pdf) maps a continuous variable to a probability density. As the name "density" suggests, the area under the pdf curve between a range is the probability of the variable being in that range.
