Appendix B



The source of these data is unknown. I would be very happy to acknowledge the source once it is known. There are 7 variables and 54 cases. These data (Tables B.1 and B.2) relate to an experiment investigating the behaviour of male stickleback. The responses of male fish during an observation period were recorded, these included the response to a ‘model’ male fish.

The data

Descriptive statistics and relationships between variables

The large standard deviations, relative to the means (Table B.3), suggest that some of these variables do not have symmetrical frequency distributions. Apart from bites and lunges few of the variables have large correlations (Table B.4) and some of the relationships (Figure B.1) do not look monotonic. It is possible that some of the significant correlations are artefacts or possibly spurious.
