Your childs class is starting a math unit on statistics (data analysis).
In this unit, your child will learn:
SP5.1 Differentiate between first-hand and second-hand data.
SP5.2 Construct and interpret double bar graphs to draw conclusions.
They will know that:
Tables and graphs can be interpreted as data.
Data can be displayed in a variety of ways.
Data can be collected and organized.
Data can be collected from a sample, rather than from an entire population.
Inferences can be made from data displayed in tables or graphs.
Data can be used to make predictions.
They will gain skills to be able to:
-recognize the difference between first and second hand data
-compare a bar graph and double bar graph
-create a double bar graph
They will inquire:
When might you use first-hand or second-hand data in a real life situation?
Can you differentiate between first and second hand data?
What is the difference between a bar graph and a double bar graph?
Can you create a double bar graph?
You can:
Watch for examples of tables and double bar graphs in newspapers,
magazines or on the internet.
Ask your child what the tables or graphs convey.
