 * development and use of formulas for the area and perimeter of triangles and parallelograms
 * determination of the internal and external angle sums for a polygon and confirmation by measurement
 * estimation of the likely maximum and minimum error associated with a measurement
 * appropriate use of zero to indicate accuracy of measurement; for example, a piece of timber 2.100m long is accurate to the nearest mm
 * recognition of the mean value of a set of measurements as the best estimate, and that the range could represent the associated error

=1. The Survey = 

Design a discrete survey to ask students in the school a question. media type="youtube" key="hNvqt3GTg0Y" height="315" width="420" =2. The Experiment = = = 

Design an experiment that test something about one student (like reaction time). Repeat the test twenty times.

=3. The Graph = = = **3a.** Graph each of your results using Create-a-Graph. Identify the mean, median, range and the mode of the data.

**3b.** For the experiment, mention what the error might be based on the range. Use Excel or Numbers on iPad to sort the date.
