Section 6: Statistics in Sports Stat 2220, Espey ➢ Random Variable: a variable with different outcomes that each assume a numerical value ○ Represented with Y ○ Discrete RV: countable ○ Continuous RV: measured on a continuous scale (decimals can be used) ➢ Binomial Random Variable: How many times one two possible outcomes occurs after a series of independent trials ○ Ex: When shooting a basketball, there are two outcomes: making the basket or missing it. We decide to count how many baskets are made after four shots (four independent trials). The binomial random variable Y is the amount of baskets made after these trials. ○ To find the probability of a value of Y
