Investigate the effects of environmental factors on the distribution of maggots using a choice chamber

Other conditions, Light Wet, Light Dry and Dark Dry are less attractive as they have the average of 4, 3 and 3 respectively. Their average is much lower than the average of Dark Wet chamber. This shows that a much less number of maggots prefer these 3 conditions. Unlike the data for Dark Wet condition, the data recorded for these 3 chambers is generally stable, hence they have the standard deviation of 0.55 (for Light Dry and Light Wet) and 0.71 (for Dark Dry). These results for standard deviation shows that there is little variation in the 3 sets of data.

However, a notable factor is that in trial 2 and 3, according to my observation, one of the maggots kept moving from Dark Dry to Dark Wet. In trial 5, one of the maggots was moving from Light Wet to Dark Wet. Therefore in these 3 trals, one maggot was counted more than once which lead to the total maggots counted being 21. This incident may make the results unreliable, hence a way to amend this in the next experiment will be shown in the evaluation.
