Learning Targets and Learning Criteria
  • identify and interpret the similarities and differences in the shape, center, and spread of a data set and within real-world context if given.

  • describe the center of the data distribution (mean or median).

  • choose the histogram with the largest mean when shown several histograms.

  • describe the spread of the data distribution (interquartile range or standard deviation).

  • choose the histogram with the greatest standard deviation when shown several histograms.

  • choose the box-and-whisker plot with the greatest interquartile range when shown several box-and-whisker plots.

  • understand and be able to identify which measure of center and spread are appropriate depending of the shape of the distribution.

  • recognize the mean moves towards a skew or extreme value.

  • identify the outliers for the data set.

  • predict the effect an outlier will have on the shape, center, and spread of a data set.

  • decide whether to include the outliers as part of the data set or to remove them.

  • use their understanding of normal distribution and the empirical rule to answer questions about data sets.

Classroom Activities

Monday/Tuesday:

Whole Group:  Use worksheet called “Normal Distribution” found at the link: Bell Curve Notes.    You can watch the Khan academy video “Standard Deviation of a Population” to learn how to calculate a standard deviation.  Work the three problems on the front of the page on the board to demonstrate.  To review standard deviation, click on this link to a Khan Academy Video that shows how to calculate Standard Deviation: * Population standard deviation (video) | Khan Academy      Use this link to listen to a teacher filling in the notes for class:  https://youtu.be/MSpTUxkjYXI.    

Small Group:  Work problems 1-2 on back of note-taking page with classmates at your table.  Check answers with each other.  See key at teacher’s desk.

Independent:  Khan Academy:  Standard deviation of a population.  Finish this assignment for homework if more time is needed.  This will be graded,

Wednesday:  (1st and 3rd period will use plan from Monday/Tuesday above since they didn’t have school on Monday, Jan. 3rd)

Whole group:  (6th, 7th, 8th periods) Review Mean Absolute Deviation (MAD), Box and Whisker Plots, Dot Plots, and mean, median, mode. Print these pages back to front from this link to make a review foldable for your ISN (interactive student notebook):  ComparingCenters(Foldable7)No KEY

Thursday/Friday:

Whole Group:  Take notes on “Normal Distributions and Z-Scores” on the note-taking pages in this link:  Bell Curve Notes.   A video link of a teacher going over the notes is: https://youtu.be/MSpTUxkjYXI.  Example problems 1 and 3 on the back of the paper will be worked on the projector for the class.

Small Group:  Students will work with partners at their table to complete example problem 4.  Students can check answers with a key at teacher’s desk.

Independent:  Students will practice drawing Normal Distributions and calculating Z-Scores on Homework 2 paper which can be printehttps://youtu.be/MSpTUxkjYXId from this link (2 pages):  HW2 Normal DIstribution

Monday/Tuesday (next week):  Use worksheet called “Practice Statistics Questions” found at the link: Practice Statistics Questions

 

Assignments Due

Khan Academy: Standard deviation of a population practice from Tuesday for 6th, 7th, & 8th periods and from Wednesday for 1st and 3rd periods along with the last problems on the note-taking page front and the first problem on the back of the page.

From Wednesday:  Foldable of Box and Dot Plot, also Mean and Mean Absolute Deviation.  ComparingCenters(Foldable7)No KEY

From Thursday and Friday:  Unit 11: Statistics Homework 2- Normal Distribution & Z-Score.  Here is another link to the paper to print it:  HW2 Normal DIstribution
