Slideshow.1 – Throwing the dice 30 mins
The lass isdivided in groupsof four orve.Eah group isgiven a set of die.
Step 1 : Eah student throws a die ten times, builds a frequeny table and draws a
relative frequeny polygon, with sale 2 mfor 1 on the
x
-axis and 10m for 1 onthe
y
-axis.Step 2 : Eahstudentthrowsadieahundredtimes,buildsaseondfrequenytableand
draws a relative frequeny polygon on the same graph as step 1, with a dierent
olor.
Step 3 : Inside eah group, results are gathered to build a third frequeny table and
draw athird relativefrequeny polygon, still onthe same but using a third olor.
Step 4 : In the whole lass, results are gathered to build a fourth frequeny table and
draw afourth relative frequeny polygon, still onthe same but usinga third olor.
2 – More throws 15 mins
Results are given for samples of 10 000 throws and 50 000 throws. Eah student must
then draw two new frequeny polygons onthe same graph.
3 – Discussion 10 mins
One possible set of graphs is shown and disussed. What's going on? What are the
