[accordion-item title=”Intentionality…”]

The purpose of this assessment is for students to demonstrate their understanding of the following big ideas. 

• Frequency is the number of times a category or event occurs within a data set. 
• A relative frequency table shows each category expressed as a fraction of the total quantity or frequency.
• Relative frequency can be represented using fractions, decimals, or percents. 
•  Fractions, decimals, and percents can all represent relationships to a whole.
• The sum of the relative frequencies is 1 or 100%.
• Stacked-bar graphs display the data proportionally, relative to the whole.
• Stacked-bar graphs relative frequency. 
• Each bar in the graph represents a whole, and each of the segments in a bar represents a different category. 
• Different colours are used within each bar to represent each category.

The independent assessment will allow students to demonstrate concepts and skills related to the following learning goals: 

• I will determine the relative frequency of a category within a data set.
• I will interpret and draw conclusions based on data presented in a relative frequency table and stacked bar graph. 
• I will communicate sample data sets that could be represented using a stacked bar graph. 
• I will demonstrate an understanding of the relationship between fractions and percent. 
• I will create stacked bar graphs based on a data set with appropriate labels. 

Students might write and/or model their task independently. Students can also be interviewed by their teacher. 

An alternative assessment opportunity should be offered if this tool will not successfully capture what the student knows, understands or can do.
