Title: Interpreting Graphical Displays of Data

Speaker: Roxy Peck

Sponsoring Committee: Statistics

Date: Monday, December 8, 2014

Time: 3:00pm EST / 2:00pm CST / 1:00pm MST / Noon PST

Description: Graphical displays of data are sometimes difficult to interpret. Textbooks often use overly simple examples that don't reflect the ambiguity that can occur in displays of real data. Important considerations include:

• How closely do graphical displays based on sample data tend to resemble the population distribution?

• What does “approximately” symmetric mean and how far from symmetric does a sample distribution have to be before we would call it skewed?

• How far from linear does a pattern in a normal probability plot have to be before we would say that the population distribution is not normal?

• What kinds of patterns in residual plots should cause us to question whether a linear model is appropriate?

Using activities suitable for classroom use, this webinar will explore these questions and also take a look at how sample size comes into play when trying to answer these questions.
