- Title
Graphical analyses of bimodal frequency distributions with an example using Cancer pagurus.

- Abstract
Mixtures of two normal distributions were generated to serve as guides for probability paper analyses. Three families of curves are presented, with three relative proportions of vertical range in distributions 'A' and 'B' (1:0-5, 1:1, 1:2), three proportional ranges on the probability scale (0-5:0-5, 0-75:0-25,0-88:0-12), and degrees of overlap from 0 to 83 %. These plots are better guides to the appearance of such mixed distributions than several published formulae, and have the advantage that the results can be 'seen'. A practical example of the use of these plots is presented, based upon oxygen consumption in the crab Cancer pagurus L.
