STAT 311 Lecture 7: Statistics for Behavioral Sciences Lecture 7
Document Summary
In statistics, we use it to refer to events that are unpredictable. Random event something that may or may not occur, and that which we can assign a probability to; an outcome is unknown. We can think of a random event as a possible value that a random variable takes on. For instance, a random variable x may be the outcome of a roll of a die, and a random event might be x = 6. You flip a coin and it comes up heads. The broncos win the super bowl next year. The dow jones finishes the week up more than 50 points. The complement of an event is its non-occurrence, or its opposite. You flip a coin and it comes up tails. The broncos fail to win the super bowl next year. The dow jones finishes the week either down, or up less than 50 points.
