## Random **Variables**

This course covers Random Variables and consists of 7 topics.

Random Variables –

**In this video we show how to compute the mean, standard deviation, and variance of random variables.**Binomial Random Variables –

**In this video we show how to compute probabilities involving repeated trials with two outcomes (success or failure).**Binomial Mean Variance –

**In this video we discuss the mean, variance and standard deviation of a binomial random variable.**Poisson Random Variables –

**In this video we show how to compute Poisson probabilities in situations where in a small length of time either 0 or 1 events occur.**Normal Random Variables –

**In this video we show how to compute probabilities for the normal random variable.**Central Limit Theorem –

**In this video we show how to use the normal random variable to approximate probabilities involving sums of >=30 random variables.**Z Scores –

**In this video we show how Z scores are used to measure how “unusual” a data point is.**
