Dispersal Behaviour
In this experiment, researchers investigated the dispersal behaviour of round goby in a controlled laboratory setting, exploring how it varies under day and night conditions. Additionally, the activity levels of the goby were recorded within the experimental tank. Each goby was categorized based on its size (Small, Medium, or Large) and whether it exhibited dispersal behaviour. The activity level of each goby was also measured. The dataset comprises crucial information on the size of each goby, their dispersal behaviour, and their activity levels within the experimental environment.
1. Dispersal Behaviour:
- What percentage of round goby exhibited dispersal behaviour?
- Among the goby that dispersed, what was the average activity level?
- Create a bar plot to visualize the proportion of goby exhibiting dispersal behaviour for each size category.
2. Activity Levels:
- What was the median activity level of the round goby in the experimental tank?
- Compare the activity levels of goby exhibiting dispersal behaviour versus those that did not. Is there a significant difference?
- Generate a boxplot to visually compare the distribution of activity levels between goby that exhibited dispersal behaviour and those that did not.
3. Size and Dispersal:
- Is there an association between the size of the round goby and their likelihood of dispersal? Perform a chi-square test to determine significance.
- Calculate the percentage of goby of each size category that exhibited dispersal behaviour.
- Create a stacked bar chart to illustrate the distribution of dispersal behaviour among goby of different sizes.
4. Size and Activity:
- Is there a significant difference in activity levels among different sizes of round goby? Visualize the relationship between the size of the goby and their activity levels using a box plot, and perform a one-way ANOVA to test for differences.
