Use this document to record your answers to the tasks described in the laboratory
report assignment. When completed submit this document for marking via the
assignment portal in Canvas.
Things to note:
- All screenshots illustrating techniques used to obtain results must be
accompanied by a succinct description of their contents. - Results output by ImageJ such as distance measurements, mean and standard
deviation values, etc must be shown in screenshots to a degree that enables
your results to be verified. - When asked to discuss your results you may include anything that you consider
to be relevant or interesting (observe the word limit). - Total points 100.
- Total points for each task as shown.
- Points for each part of each task are shown in square brackets.
