Lesson: Variance of discrete random variable. The activity is in the picture. For more information, look at the sample problem in the pictures.

W After learning how to compute and interpret the variance of discrete random variable, you are now ready to apply what you've learned by doing the activity below. Your output will be graded using the rubric that follows. Conduct a survey on the number of social media platforms used by 5 of your friends or classmates and their corresponding probabilities (Note: The sum of PDQ must be equal to 1). Construct a probability distribution and compute the mean and variance then interpret the computed values. Rubric for Scoring Solutions are Solutions are Solutions are Solutions are Solutions are accurate with accurate but NOT so NOT so totally correct incorrect accurate with accurate with incorrect interpretation interpretation irrelevant no interpretation interpretation at all
