0.73 MB | 12 slides, 4 examples on handout pages
This zip file contains an instructional PowerPoint showing students how to use the Median, Upper Quartile, Lower Quartile, Upper Extreme, and Lower Extreme to make a Box and Whisker Plot. (The presentation assumes you have already taught how to find the Measures of Variation. If you have not, I have an instructional PowerPoint for that as well.) An example page is provided for the students use during instruction. There are 4 examples on the handout and all 4 examples are solved during the presentation.
I have also included an additional PowerPoint I use on the following day to clarify with the students what can and cannot be found when they are given a Box and Whisker Plot, but not the data.
In these PowerPoint files I have done a bit of stacking on the slides that transition out when necessary. I also use sounds as I've found it keeps the students more engaged.
Please note: When I have my student find the median, we find the half way point, we do not use the cross out method. When I have done that method in the past I found students had crossed out the data they needed for the quartiles.
