AS3.1 Practical Investigation (Internal)
The practical investigation involves planning, carrying out investigation, collecting data, analysing results and discussion.
The following evidence is required for an ideal investigation.
  • accurate data relevant to the aim based on the manipulation of the independent variable over a reasonable range and number of values
  • a description of the control of other variable(s) that could significantly affect the results
  • the use of techniques to improve the accuracy of measurements
  • uncertainties appropriately calculated in all processed data
  • a linear graph with error bars and appropriate error line, based on sufficient data, relevant to the aim
  • a conclusion that is relevant to the aim, based on the data, and is drawn from information calculated from the linear graph, including processed uncertainty
  • information calculated from the linear graph is correctly rounded
  • a discussion that evaluates and explains the validity  of the results, and   considers relevant physics theory.
