Grade 7 – Data Management
By the end of this unit, I will be able to:
· Collect and organize primary data and second data
· Accurately display the data using charts, frequency tables, circle graphs
· Make and evaluate convincing arguments based on the analysis of data (ie trends)
· Identify bias and unbias collection methods
· Identify graphs that present data in misleading ways
· Determine how outliers may or may not affect mean, median and mode
Note: Most of the unit will not be found in the textbook with the exception of:
· 3.2 Avoiding bias (page 84)
· 3.5 Frequency tables (page 98)
· 3.6 Mean, Median and Mode (page 102)
Instead of teaching this unit in small chunks, there will only be a couple of formal teaching days. Students will be working independently as well as in small groups for most of the unit.
Students will use Google Forms and Sheets in this unit to help display their data.
