GGBChat4: Statistics 1

ggbchat, Jul 17, 2014

Sketches used and discussed in the GeoGebra chat #ggbchat that happens on Twitter on alternate Wednesdays. The theme of this chat was statistics. NOTE: these sketches work best if you download them as they're buggy online in the student worksheets.

One Variable Statistics

Note: this sketch seems to work better when downloaded than on student page. GGBChat 4: Q3a: Try basic 1-var tools here http://tinyurl.com/onevar OR watch this short video http://tinyurl.com/singlemov #ggbchat Q3b: What questions could you ask a S from this type of visualization? @MrLeiss A3: Why might someone prefer the red graph? Why might someone else prefer the blue graph? A3: Do either graph hide any information (even partially) that is more visible in the other? @gwaddellnvhs A3b: Is it possible for the red and blue graphs to be from the same data set? @a_mcsquared A3b: Which graph shows some actual data, and which one is only condensed data?
