We have the election results as a focal point for the next two weeks. An election is really a census of the entire population of the voting public (over 18 years old).
The final 50% of your grade will be from a test/assessment done over one hour. This part of the topic will be done solo (as opposed to your presentation done in pairs).
The specific things that you have to be able to do are...
- Put raw data (in a random order) into a stem and leaf graph. This may be sorted or unsorted. This may be a back to back stem and leaf graph.
- Calculate from stem n leaf graph the measures of the centre (mean/median/mode) and the spread (range and interquartile range).
- Use the PPDAC cycle of inquiry (know what happens when and why it happens).
- Draw box n whisker graphs carefully in grid paper (using a ruler and correct scale/sizes).
- Read graphs to get information (histogram/pictograph/bar/pie/box n whisker).
You are allow a calculator but not the computers for this part of the topic.
