Investigate the effects of environmental factors on the distribution


According to the results collected, the most noticeable factor we can see is that the maggots are most attracted to Dark Wet condition. The number of maggots distributed into this chamber is the highest compare to other chambers. This is evident as it has the highest average of 11. This result therefore supports my hypothesis.

Although the results obtained for Dark Wet condition has the highest standard deviation of 1.14, being that it is unreliable compare to the other 3 conditions, however, the number of maggots in this chamber is always much higher than those in other chambers. Therefore, the variation of this set of data caused the high standard deviation but overall, still supports the hypothesis.

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 ...
