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.
