| (a) |
Explain the importance of accurate labelling of line graphs. |
| (b) |
Determine whether a set of data should be represented by a line graph (continuous data) or a series of points (discrete data) and explain why. |
| (c) |
Describe patterns seen in a given line graph or a graph of discrete data points, and describe a situation that the graph might represent. |
| (d) |
Construct a graph (line graph or a graph of discrete data points) to represent data given in a table for a particular situation. |
| (e) |
Interpret (through interpolation and extrapolation) the line graph or graphs of discrete data points for a situation to make decisions or solve problems. |
| (f) |
Observe and describe situations relevant to self, family, or community in which data might be collected through questionnaires, experiments, databases, or electronic media. |
| (g) |
Select a method for collecting data to answer a given question and justify the choice. |
| (h) |
Answer a self-generated question by performing an experiment, recording the results, graphing the data, and drawing a conclusion. |
| (i) |
Answer a self-generated question using databases or electronic media to collect data, then graphing and interpreting the data to draw a conclusion. |
| (j) |
Justify the selection of a type of graph for a set of data collected through questionnaires, experiments, databases, or electronic media. |
