Rocky Shore Experiment
The Rocky Shore Experiment
Research Question: How does type of substrate affect the variation of species and vegetation as you move away from the seashore at a Rocky Shore?
Hypothesis: As we get further away from the seashore, there would be a decrease in the number of species and vegetation found. Also, the type of substrate will have a major affect on the biodiversity.
Background Information:
A rocky shore is an intertidal area of seacoasts where solid rock predominates. Rocky shores are biologically rich environments, and make the ideal natural laboratory for studying intertidal ecology and other biological processes. Because they are so accessible, they have been studied for a long time and their species are well known.

24+31+39+26+16 / 5 = 27.2
For the standard deviation, subtract the total number Nerita Chamaeleon identified by each group by the mean value. Then square the values found after the subtraction and add them all. Then divide the total number by a number less than the number of groups. Square root the value found and that will give you the standard deviation.
Standard Deviation = 8.53
Holothuria Atras:
To find the mean, add the total number of Holothuria Atras found by each group and divide it by the total number of groups. 5+0+3+0+0 / 5 = 1.6
For the standard deviation, subtract the total number Holothuria Atras identified by each group by the mean value. Then square the values found after the subtraction and add them all. Then divide the total number by a number less than the number of groups. Square root the value found and that will give you the standard deviation.
Standard Deviation = 2.30
Average Mean and Standard Deviation of the vegetation found at the Rocky Shore.
Algae:
Total amount of Algae found per group:
Group 1=105
Group 2= 100
Group 3=159
Group 4=123
