1.) Explain the purpose of control techniques.
The main purpose of control techniues is to make sure that when you are doing research you have to treat each groups you are doing the research on the same way during the conduct of the experiment but importanly is designed to measure specific aspects about the performances of the participants, and its processes.

2.) Explain why random assignment is the best control technique for equating groups. Random assignment is to make sure that every participant has an opportunity and chance of being placed in any group. It also helps to ensure that any differences either between or within the groups are not systematic at the outset of the experiment. Random assignment is the best because each participants are randomly assigned to different groups without knowning, either on the experimental group, or treatment group. Random assignment also make sure that participants in a cause and effect study are unbiased.

3.) List the major control techniques that are carried out during the experiment. The major control techniques that carried out during the experiment are randomized counterbalancing ,order effect, complete counterbalancing, incomplete counterbalancing, …show more content…

Participant are usually controlllled by folowing these steps: "Standardization of procedures and instructions (Ensures that in every step of the experiment procedure all participants are treated in the same way) Single blind procedure (the participants may know about the goal of the experiment, but do not know which group they are in) Double blind procedure (Neither the experimenter and the participant knows who is in each condition/group) Deception (Providing all participants a rational for the experiment that is unrelated to the true its true

When James Lind performed his experiment, he chose the six remedies with an intention to not have an effect of the variances. He selected 12 men from the ship who suffered scurvy. He divided those 12 men into pairs and provided supplements to their basic diet for two weeks. Based upon the work of Ronald Fisher, why are the following principles of Experimental design important? Comparison: The purpose of comparison is to make sure

Single Subject designs include robust and influential methods for manipulating the behavior of individuals, ethical concerns are extremely important. Furthermore, ethical and humane treatments are crucial to follow during intervention and treatment. Walker and Shea (1991) had several questions to address when establishing treatment. Who will manage the behavior, who decides what behavior is to be changed, who decides what type of intervention is to be used. Who decides if the intervention is ethical, who determines if the administer behaves ethically.

This can be more difficult than it sounds, because it can be difficult to anticipate how participants will react to a study. It is usually easy to recognize when someone’s physical safety is in jeopardy, but it is complicated to recognize when a person’s emotional well-being is at risk. Researchers have an obligation to minimize any procedures that have the potential to cause harm to your participants. In general, avoid designs in which participants could be humiliated, embarrassed, scared, anxious, stressed, saddened, or discouraged. The participants’ physical and mental state should be the same as when they arrived for your experiment then by the end your experiment.

The people who participated in this experiment, were aware that they were killing someone. His finding included that normal people who were influenced by a person of authority obey the command they were given. It was very easy for the teachers to push the buttons when they were under pressure. Just like the Nazi’s did when Hitler gave them

Skinners experiment was based on operant conditioning, using the concept of discrimination learning, he carried out experiments on animals with the idea that their behaviour is predetermined by their environment and using a well controlled environment would allow him to in turn control their behaviours using a range of triggers. Using reinforcement and expectancy, the animal associates acting out certain behaviours with rewards. (Toates, F., 2010, pp. 165-167) After performing a number of experiments on rats using mazes, he subsequently designed the Skinner box.

This happens when participants are misinformed or misled about the purpose of the experiment. In Milgram’s study, deception occurred when Milgram allowed the teachers to believe that they had been shocking the learners. He also made the volunteers believe that the learners were also selected, but they actually worked for Milgram. When, in reality, the learners had been unstrapped from the chairs before the experiment began. This violates the guidelines because full information was not disclosed about the study, and it led to distress among several participants.

However, each participant continued to listen to the experimenter who told them to continue. Never once then the participant tries to challenge the experimenter, they only continue to further the experiment and administer the shocks. The three main factors: obeyed but justified themselves, obeyed but blamed themselves, and the those who rebelled. The participants blame everything on the experimenter and said it was their fault.

Although I have not had a chance to help or conduct a research, I think all methods of study contain a bit of bias. After, researchers and scientists are human. Anyhow, random assignment is a useful technique yet, it is important to consider other possible methods of assignment and to work out which one will beneficial for the study the most before committing to one type of method since there many types of samples. For instance, if the experiment were to look at the treatment of depression using Electroconvulsive therapy (ECT) treatment and drug therapy, it would be hard to randomly allocate the groups. Studies have shown that people with severe, chronic depression recover better than those with mild depression when it comes to ECT treatment.

It does so by having the subjects all placed in the same environment with the same instructions. The subjects’ job is to shock the “learners” if they give out incorrect answers. The learners are actors implanted by the experimenters. The shocking increases the more answers they get wrong. Some of the “learners” being shocked are literally begging for the shocking to stop, some even faked death yet almost all of the subjects continued the shocking.

Random assignment is a very important part in a experiment/research project because you have to make sure that you have randomly assigned the participants in a group, otherwise the experiment/research will become a selection bias. It is important to prevent selection bias because it can have just as big of an effect on the project to enable itself to ruin the study and making the results invalid. So i would ensure this from not happening by either generating a random number selector or by telling students to pick from a basket of random numbers to choose from. My population in my experiment would be students in the 10th grade and even though it is very hard to get a perfect representative sample the larger the population the lower risk of a non-representative sample, so in order to pick a good representative sample i would gather a major variety of the 10th grade students in a school, and make sure there is a great geographically/demographically representative who has very similar characteristics from everyone else, or picking randomly from a number generator. I would try avoid outliers because they generate bias, which will throw off all your sample means and just mess up your final conclusion for the
