    Statistics for All-the Flip Side of Quantitative Reasoning a statement by
    NCTM President J. Michael Shaughnessy NCTM Summing Up, August 2010 The twin sister of the “certainty” in mathematics is the “uncertainty” in statistics. We must prepare our students to deal with both types of quantitative reasoning as they grow in the mathematical sciences. Statistical literacy has risen to the top of my advocacy list, right alongside numeracy,
    Statistics Links and perhaps even ahead of “algebra for all.”For example, suppose that 24 boysResources Have Been Moved To and 24 girls try out for 35 slots in a student orchestra. After the tryouts are over it turns out that 21 girlsBeing Updated At
    Probability
    and 14 boys were selected for the orchestra. Does that outcome seem reasonable, or might it indicate discrimination against boys in the selection process? Are you impressed or suspicious when you hear that one medical treatment showed a 20% increase in the five-year survival rate as compared to another treatment?
    "The Joy of Stats" by Hans Rosling. Things are changing fast and it looks like statistics is leading the way. I am sorry to mass email this to everyone . . . but it may be the greatest video about statistics i have ever watched. 58 minutes. I am not much for showing videos in a math classroom, but I will be showing this one just as soon as I can get it past our school firewall. It is worth the time as far as I am concerned. So if you need a break from thinking about Nesa . . . this can bring some of the joy of what math should be back into you and your students lives. Follow this link

    move critical points to number line to show how the length of the whiskers and parts demonstrates the spread of data
    To develop flexibility and understanding of what the mean represents distribute pennies or chips to each person for the number of people in their family. Equally distribute the coins to find the mean without dividing.
    See other ideas for collecting data with box plots below.
    Homework Sums
    See a video demo Divide students into groups of 3. Each person receives a set of numbers. Each student finds the median of their group. The sums of the median of all three students is shown to the teacher. If the sum is correct the groups goes to the mode, if the sum is incorrect they find the error and try again. Complete with finding mean and range.

    How Old is the Oldest Person You’ve Know? Video of Commercial
    Recreate the advertisement with students. Three groups could be compared. Use data from students, their parent/guardians, and grandparent or other relative. Use this data to create graphs and box plots to compare the collected data. Predict differences in the data spread, mean, medians, outliers and other measures. Create a live dot plot with students and scores. Arrange in line and fold to find median, 1st and 3rd quartiles and create a box plot with rope.

    Piecemeal Problem
    Cooperative activity where a problem is divided into parts. Each person in the group receives a part of the problem. They use the parts to solve the problem and then go to another problem. Piece-meal Problems stats.doc {Piece-meal Problems stats.doc}

    Correlations
    Correlation Stations Students plot data for several questions that show positive, negative, or no correlation. Have students predict the relationship before beginning. Students plot data at each station. This blog shows sample pictures of the graphs as well as recommendations for conducting the activity. Sample questions:

    Human Bar Graph
    Use the number of people in your family, number of pets or another number students would have some interest in exploring.
    Create human bar graph, have students stack themselves along appropriate x-axis, then note mode and range
    Move bar graph to a single line in order from low to high, fold the line to find median, fold again to find quartiles

    Circle Model for Probability of Compound Event
    Four identical pieces of chocolate are on a plate. Three of them are cream filled and one is cherry filled. What is the probability of getting a cream filled and then a cherry filled chocolate? Document with template.

    Fraction to percent. Have students flip a coin to decide if they will have a candy bar or apple for break. Keep track of the cumulative fraction and percent of time that the apple is the snack. Plot the cumulative percent versus the number of trails. Related article Teaching Children Mathematics December 2011 p 328
