Now have a closer look at the results. These should be analysed and presented in a clear way in your report. In your report you will need to present a table and graphs showing the overall mean for each group of rats. First, though, you will need to calculate a mean of the measurements from each rat in order to calculate the overall group means. Mean values can be calculated manually from Tables 1 and 2, or if you are familiar with using spreadsheets, you can use the appropriate functions in the Excel spreadsheet .

• a table showing the group means you have calculated to three decimal places (you should have four group mean values in your table)
• two software-generated graphs, one for each of the structures investigated, showing the group mean results clearly
