In this video we’ll introduce you to box plots and measures of spread, and to shape and oddities. We’ll use our knowledge to look at our data, to draw insights from it, and possibly ask more questions about the data. Why are weights bimodal and heights not?
After you’ve watched this video, you should be able to answer these questions
•What sort of “oddities” should we look for and what sort of questions should we ask we see them?
•What is the defining property of a median? the first quartile? and third quartile?
•What information does the box plot add to the dot plot?
•What is the interquartile range and how does it relate to the box plot?
•What is an “outlier”?
•What does “positively skewed” mean?
•What does “bimodal” mean?
