Yes. It is recommended that students do so. Otherwise, they will have trouble completing the test.
At the end of the test, the supervisor will collect all the pages and restaple them together.
Yes. Each team is given their own copy of the test, and may use it for calculations.
However, calculations recorded on the test will not be scored. Only the answers recorded on the ZipGrade form for will be scored for Part 1.
Bar graphs are descriptive. They compare discrete amounts of data such as the number of things. They help us make generalizations and see differences in the data.
Line graphs show a relationship between two variables. They are useful for showing trends in data, especially continuous changes over time, and for making predictions.
Data which is continuous can become discrete if it is aggregated. For instance, we could measure the number of phone calls received each hour, or each day. If we add the data for each month together and display it by month, the data is no longer continuous. By hour, the data would more appropriately be displayed with a line graph. By month, the data would be more appropriately be displayed with a bar graph.
