In the first of two lessons, students will distinguish between discrete and continuous random variables. They will construct probability distributions. Students will determine if a probability distribution is legitimate. They will find the mean, standard deviation, and variance of a probability distribution. In the second lesson, students will determine if a probability experiment is binomial. They will find binomial probabilities using the formula and technology. Students will create a binomial distribution. Students will also learn how to calculate the mean, variance, and standard deviation of a binomial distribution. These lessons come in the form of student guided notes with keys. These lessons are appropriate for a high school statistics course or an introductory college statistics course.
