Answer:
This study is an example of a blocked design experiment.
Explanation:
Directly, we can say that a blocked design experiment is an experiment that has the object of study divided into blocks that are repeated throughout the experimental unit. In the experiment presented in the question above, we can recognize these blocks when the researcher decided to divide the coastline into 30-meter plots, installing some with breakwaters and others without. Each plot, in this case, is a block.
This type of experiment requires that all blocks are the same and be subjected to the same factors. This allows the researcher to have control of the entire experiment and obtain homogeneous results in each block. In the experiment shown above, we can see that this control has been impaired, since the coastlines to the east and west of the lake receive very different wave patterns due to the wind. This will prevent the blocks from having homogeneous results, since the action of the breakwaters will be affected differently in each block.
First, there were two independent clinical psychologists who were present or on call 24 hours a day. They had the power to intervene and to remove anyone from the study if they thought they were in distress.
Second, we had paramedics and security guards on hand and ready to intervene at a moment’s notice if anything untoward happened in the study.
Third, the study was constantly monitored by members of a five-person independent ethics panel. This was chaired by a Member of Parliament and also included members of the Holocaust Educational Trust, the Howard League for Penal Reform, the BBC’s Independent Editorial Policy Unit and a senior academic psychologist. This committee had the power to change the way the study as a whole was run and to terminate it if they had ethical concerns.
