If you're not right-handed, are you wrong-handed? Young statisticians calculate the percentage of left-handed people using a given data set in the assessment task. They plot data on a scatter plot and consider how the line of best fit relates to the data.
- Have pupils include a point on the scatter plot to represent their own class
- Task requires graph paper
- Learners need to have experience with scatter plots in addition to ratios, percents, and proportional reasoning
- Simple context makes the material easy to understand
- Teacher resource includes answer key and simple rubric (partial vs. full credit)
- The way the task prompts individuals to find a trend line is not how it would be taught in a classroom situation
