Hypothesis:
Habitat A will have a greater biodiversity, because there is more opportunity to create different niches.

Table 2:
2. How many species of spiders did you find in…
Habitat A: 3 Habitat B: 2
3. What was the AVERAGE number of spiders you found per quadrat?
Habitat A: 6 Habitat B: 4.6
4. Four quadrats can fit in this area. How many spiders do you estimate are found in the whole area?
Habitat A: 24 Habitat B: 20
5. Look at the bottom sheet of paper with the spiders on it. How many spiders are there in…
Habitat A: 22 Habitat B: 20
6. Was your estimate close to the actual number of spiders in the area?
Yes I was off by two for both.
7. Why might there be a difference between your sample estimate and the actual number?
The spiders are evenly distributed, therefore the likelihood of the data being accurate is low.

What is the number of each species?
What is the PROPORTION of each of spider in your habitats? species in your habitats?
What is the PROPORTION of each of spider in your habitats? species in your habitats?
8. Based on the proportions you just calculated (Table 4), do you think the species are evenly distributed within the habitats?
Habitat A: NO Habitat B: NO
9. Is this what you think it would be like in nature? Why?
Yes, because some species live in clusters while others live separated.
10. Was your original hypothesis supported by the data you collected today? Why or why not?
Yes I was correct. Habitat B lacked variety in it's environment, while Habitat A had more variety in trees, rocks and grass.
11. What did you learn about doing a biodiversity quadrat study?
Habitat A: NO Habitat B: NO
