Weighted Average • A weighted average is a mean calculated by using frequencies of data values. Suppose that 30 movies are rated as follows:

Definitions • For numerical data, the weighted average of all of those outcomes is called the expected value for that experiment. • The probability distribution for an experiment is the function that pairs each outcome with its probability.

Finding Expected Value • The probability distribution of the number of accidents in a week at an intersection, based on past data, is given below. Find the expected number of accidents for one week.

Box-and-Whisker Plots A box-and-whisker plot shows the spread of a data set. It displays 5 key points: the minimum and maximum values, the median, and the first and third quartiles.
![BoxandWhisker Plots The quartiles are the medians of the lower and upper halves Box-and-Whisker Plots • The quartiles are the medians of the lower and upper halves](https://slidetodoc.com/presentation_image_h/996b4a98c9880b98db70cbfb3f86da20/image-8.jpg)
Box-and-Whisker Plots • The quartiles are the medians of the lower and upper halves of the data set. If there an odd number of data values, do not include the median in either half. • The interquartile range, or IQR, is the difference between the 1 st and 3 rd quartiles, or Q 3 – Q 1. It represents the middle 50% of the data.
