INTRODUCTION TO STATISTICS• Students should have a basic understanding of statistics: collecting,

organizing and displaying data on line plots and bar graphs.• You may want to teach/review mean, median and mode as this is not

covered; however, my advanced classes have usually seen it.• Begin with the Enter ticket to check prior knowledge.• With those results you can guide the class discussion and clarify

misconceptions.• The next slide includes sample graphs to show and use for discussion…

these vary from hand made to interactive and fun to watch!

THAT YOU WILL CREATE!

Dot Plot 4- Excellent representation, accurate, no mistakes

3- Good representation, mostly accurate, 2-3 mistakes

2- Fair representation, 4-5 mistakes, needs some improvement

1- Poor representation, 6+ mistakes, needs to be redone

Correct graph        Accurate titles & labels        22 data points accurately represented

       

Number line is correct and appropriate increments

       

The vertical increments/spacing is appropriate to show the correct shape of the plot

       

Total Points:        Total Overall Points:        Overall Grade:        

DOT PLOT RUBRIC:*Sample Scoring: A is 14.4+ points; B is 12.8-14.3 points; C is 11.2-12.7 points; D is 9.6-11.1 points; F is 9.5 and below. (Please adjust scoring as preferred.)

• Now show on the board the enter ticket grade data and have students copy the data down.

• Let them begin to organize the data and work on their graphs.• This is where students are either working with graph paper, rulers and

maybe markers to create their graphs or you can have students working with excel or geogebra to create… if available and you are comfortable with this technology.

• Walk around facilitating discussions to be sure that students are adding all appropriate information and understand the data they are displaying.

• The next part would be to turn in graphs and take the exit ticket.• A continuing point if time allows might be to compare the two sets of

scores.
