BIG IDEA: Graphs are powerful data displays, since visual displays quickly reveal information about the data.
The overall curriculum expectations for this unit are:
- collect and organize discrete or continuous primary data and secondary data and display the data using charts and graphs, including continuous line graphs;
- read, describe, and interpret data, and explain relationships between sets of data
Don't you wish this highlighted part was in English 😕
Discrete data is counted, like the number of students in the class.
Continuous data is measured, like the weight of children' s backpacks.
Primary data is collected by the researcher.
Secondary data is information gathered from analyzing results (like a census).
