This course discusses properties and applications of random variables. For instance, how many customers are likely to arrive in the next hour? Whatâs the probability that a lightbulb will last more than a year?
When youâre done with this course, youâll have enough firepower to undertake a wide variety of modeling and analysis problems; and youâll be well-prepared for the upcoming Statistics courses.

Kursinhalt
This course discusses properties and applications of random variables. When youâre done, youâll have enough firepower to undertake a wide variety of modeling and analysis problems; and youâll be well-prepared for the upcoming Statistics courses. Weâll begin by introducing the concepts of discrete and continuous random variables. For instance, how many customers are likely to arrive in the next hour (discrete)? Whatâs the probability that a lightbulb will last more than a year (continuous)? Weâll learn about various properties of random variables such as the expected value, variance, and moment generating function. This will lead us to a discussion of functions of random variables. Such functions have many uses, including some wonderful applications in computer simulations. If you enjoy random variables, then youâll really love joint (two-dimensional) random variables. Weâll provide methodology to extract marginal (one-dimensional) and conditional information from these big boys. This work will enable us to study the important concepts of independence and correlation. Along the way, weâll start working with the R statistical package to do some of our calculations and analysis.
