Descriptive Statistics

Descriptive Statistics

​If you had the daily temperature for each of the last 1,500 days, how could you summarize that information for someone else to make it easy for them to understand?

​You just took a test in class. How can you determine the class average?

Your teacher told you that the average for both sections of a class was 85 but one section has higher variability. 

What information does that statement convey?

Today's Objectives

1. Identify, describe, and distinguish measures of central tendency and variability

2. Apply the properties of central tendency and dispersion to solve problems

Please silently read the handout notes pages 40-41 (Unit 4.2) [4 minutes]
