5 Number Summary. Even Numbered Data Sets. Even Numbered Data Sets. If the data set has an even number of numbers, we find the mean of the two middle numbers to find the median of the set 2, 4, 5, 6, 7, 8, 9, 11, 19, 20 The median is 7.5. Even Numbered Data Sets.

ByOutliers. Do Now. Bill Gates makes $500 million a year. He ’ s in a room with 9 teachers, 4 of whom make $40k, 3 make $45k, and 2 make $55k a year. What is the mean salary of everyone in the room? What would be the mean salary if Gates wasn ’ t included?. Mean With Gates: $50,040,500.

ByChapter 5 – Measurements of Variability. Math 22 Introductory Statistics. Measures of Variability. Range - The difference between the highest and lowest measurement. Range = Highest – Lowest Deviation = Observation – Mean . Standard Deviation and Variance.

ByThe study of randomness. Kerrie Allen Jennifer Davis Chris Alexander. Observation. The percentages of heads rarely reaches below 50 percent. The minimum number is 25 percent and the maximum is 100 percent. From the raw data on the previous slide you see we collected 14 heads and 11 tails.

By5-Minute Check on Lesson 1-3b. When do we use each measure of spread? Why do we divided by n – 1 in calculating the standard deviation? Which measure of spread is resistant? What is the formula for determining outliers?

ByChapter 1 Exploring Data. Introduction. Statistics: the science of data. We begin our study of statistics by mastering the art of examining data. Any set of data contains information about some group of individuals. The information is organized in variables. Individuals:
