...The experiment I chose is titled "My Children: The Food Experiment". In summary, this experiment consists of two parents who confine their children from any appealing desserts, promotions, and logos. Their goal was to have their kids discover what they like or dislike through a direct contact. The parents encouraged them to explore everything for themselves. They did not want to have anyone disclosing what they should or should not eat. To my surprise, the children found foods that grow from the ground more desirable rather than sweets and sodas. In the end, when the children started school they admitted they were the main ones who attached to greens and they loved it. I believe this analysis was definitely outlined and it worked. The parents...

...Examine the reasons why some sociologists choose to use experiments when conducting research. Study the reason why sociologist prefer to use experimental methods when carrying out a research There are many different types of experiments that can be conducted by sociologist, in order to help with the research that they are planning to carry out or just to help further prove their hypothesis. There are three main experimental methods that sociologists may choose to carry out their research/study. These three experimental methods are: Natural, field and Comparative. Each of these experiments has their own advantages and disadvantages. These positive and negative factors can analysed by practical, ethical and theoretical limitations and strengths that can be considered. This essay will be looking at each of these in detail. But, firstly what is an experiment? An experiment is a way of investigation a cause and effect relationship between independent variable and dependent variable. The first type of experiment that sociologist may choose to use in their research is, laboratory experiment. Laboratory experiments are conducted in a control setting, (this means that IV (The independent variable) and DV (dependent variable) can be controlled and manipulated by the researcher). Participant are given instruction to carry out certain tasks, in a normally manner. From this, the researchers are able to observe behaviour and be able to see cause and affect relationship between variables...

...of the scientific method. 3. Independent variable: The experimental variable or the one change within the experimental groups that the purpose of the study is testing. In this study, the independent variable is the caffeine given to the experimental group. 4. Dependent variable: The experimental result or the result of the independent group and the data the supports the answer to the proposed question and what the hypothesis predicted will be the outcome of the experiment. In this study, the dependent variable was the 30% decrease in blood glucose in the experimental group that was supplied coffee/caffeine in diluted water. The other dependent variable was the increase in blood glucose concentrations in the group that only drank water. 5. Controlled variables: In an experiment, it is important to keep all other variables as constant as possible so ensure that it is the independent variable that is affecting the result, and not other variables that could be affecting the result. In this experiment, the controlled variables were the similar composition of diets and the living conditions (same size cage, lighting, shavings in cage, etc) 6. Control group: The control group is what the experimental group is compared to. The control group does not receive the experimental conditions. In this study, the control group was the group of mice that was given water 7. Data: The raw data/observations gathered from the experiment. From this experiement, the data that was gathered was average...

...hypothesized that sleep deprivation negatively affects an individual’s ability to respond to sound, regardless of the sound’s intensity. Using a reaction timer, we assigned four individuals as an experimental control that reported seven to nine hours of sleep and tested them at low, medium, and high sound intensities to see if the intensity of the sound does indeed have a significant effect on reaction time. Then, we tested the reaction time of four sleep deprived individuals who reported five hours of sleep at each of the sound intensities. We randomly selected a sound intensity during each trial to attempt to minimize the effects of anticipation. If sleep deprivation harmfully influences an individual’s capability to react to sound (regardless of intensity), then sleep deprived individuals will react more slowly to low, medium, and high intensity sounds compared to well-rested individuals. The mean reaction times to the sound intensities in the experimental control are 0.706, 0.622, and 0.453 seconds for the low, medium, and high sound intensities, respectively. The mean reaction times for the well-rested group are 0.662, 0.575, and 0.504 seconds. A T-test revealed that there is significance between the low sound intensity reaction time and the high sound intensity reaction time for the experimental control (P-value 0.05). Another test revealed that...

Monzon-Medina DUE 05/14th/2015 BIOLOGY ARTICLE Introduction Several lines of evidence support the claims surrounding the knowledge of biology. To begin I will discuss experimenting of drugs and other forms of biology linking to different topic on experiment. Then to discuss the history that link with the 17th century thinker. After that I will explain the three basic assumptions or principles of biology. BIOLOGY ARTICLE Experimental Biology This claim surrounding the knowledge of biology, is to begin with experimenting on different form of living things using drugs and other ways to test, our ideas, according to scientific principle on one occasion people have been engaging in experiment for as long as we are learning to eat and develop life saving drugs and medical treatment. Identifying the toxic chemical in our environment and food supply lab works is made evident to support research of modern lives (extracted from biology article 2013 ) this article relate to this course in many form. E.G. Biology dealt with plant, animals and human which is the component of biology it also dealt with research and experiment. In biology today book there is a subtopic evolution of diseases it explain how micro organism existed for many years it also explain the deference between pathogen and armless. (Star 2013).

...Expectations of an Ingroup: interactions within ingroups and how they punish deviant members Abstract Ingroup and outgroups in society view punishment of members differently, ingroups especially. The variables in this study were the group in which the offender belonged to and the writing task. In the study there were 6 male and 27 female psychology students they participated to aid in writing their research paper. Participants read a fictional scenario and were then asked to determine a fine and answer four questions that judged fairness and justice. The hypothesis was that the ingroup would judge deviant ingroup members higher on a retributive justice scale and give them a higher fine. The results of this study showed that when it came to justice the ingroup rated deviant ingroup members lower then the outgroup but created a higher fine. Expectations of an Ingroup: interactions within ingroups and how they punish deviant members In society people are divided into two groups the ingroup and the outgroup both Social Identity Theory and the Black Sheep Effect deal with the idea of these two types of groups. Social Identity Theory is the expectation the ingroup offenders would be treated less harsh than outgroup offenders (Gollwitzer & Keller, 2010). While the Black Sheep Effect states that people see unlikable ingroup members more adversely than unlikeable outgroup members (van Prooijen & Lam, 2007). The theory that these two support is that ingroup members judge deviant...

...nature but without the explanation of how it came to be. For instance the Universal Law of Gravitation is a principle regularity of how two particles attract each other. Whereas a theory may be explained as an extension of a hypothesis intended to explain something in nature. For example The Big Bang Theory is a hypothesis that has gained attention and evidence to support it. Mayonnaise Experiment In my double blind study to test my hypothesis that mayonnaise facials cause warts in humans I will have two different groups, my control group and experimental group. The subjects who get the Mayonnaise facials will be in the experimental group and the subjects who receive a traditional facial crème will be the control group. The doctor or scientist in charge should not be informed of which group is the receiving the mayonnaise facials, this will cause neither the subject nor the researchers to form any unconscious bias. The experiment should consist of multiple races to show any other variables. This experiment will last one month with weekly reports from the subjects based on how the experiment is going if there are any side effects or if the facial seems to be working.

...uncovering the mysteries of human and animal behavior are descriptions, explanations, prediction and control. Descriptions involve observing and taking notes on a behavior and explanation helps create theories. Prediction helps find out what might happen later on or in the future and finally, control seeks to find out how we can take a behavior we do not like and change it into one that we do. 2. Psychologists use the Scientific Method in research design so that they can reduce the amount of any kind of bias that could affect the research. They also use it to reduce the amount of errors in the experiment that might lead to inaccurate results. 3. Replication is taking a study and doing it over and over in the exact same way and managing to get the same results each time. This is important because it lends credibility to their research and allows other people who replicate the experiment an opportunity to predict behaviors and possibly control them. 4. Naturalistic Observation involves watching people in their normal everyday activities without getting involved. You would conduct this observation by going to their home and observing them live their lives without speaking or interacting with them. 5. In a case study you would gather all the information you could about the individual in extensive detail from birth to present. To conduct this you would have access to their medical records, interviews with their friends and family, school records, etc… 6. You would use a case study...

...has brought some positive changes to some Health care facilities. There are three factors that have been constantly tested to improve patient care. These factors are: 1) fall rates 2) call light usage and 3) overall patient satisfaction. Previous researchers have done experiments that may have helped with improving the three factors. Reduction in patients’ injury due to falls is one of the safety goals of the Joint Commission. Research would suggest that patient’s falls can be damaging to the patient, their family members, staff, and can cause increase in health care cost. Prior studies have acknowledged the importance of fall prevention and patient satisfaction in hospital settings. Nurses, who are the primary care-giver for the patients, are the central impact of patient care. Therefore, the researchers depended on the medical-surgical nurse specialists (CNS) and nursing managers (NM) to make sure that all the patients’ needs were met in order to address the factors mentioned before. The researcher’s purpose for this study was to show the effect that hourly rounding has on the three factors: fall rates, call light usage, and patient satisfaction. Questions that the researchers had prior to the experiment were educationally answered by other researchers. Three previous studies showed that hourly rounding decreased call light usage and increased patient...

...The Body Fat Loss Experiment Does taking a thermogenic fat loss supplement cause an extra decrease in body fat or is it just the extra exercise and dieting from the individual's commitment itself that causes a greater body fat reduction? Thus, making people believe the excellent results couldn't of resulted on their own without the extra help from the thermogenic? I personally believe that the thermogenic supplement can cause an extra loss in body fat if taken properly. In this small experiment, I (Sean) and Ricky were the experimental group taking a thermogenic supplement from USP labs called OxyElite Pro for 4 weeks. Well my friends Luca and Adrian were the control group who had not taken anything for 4 weeks knowingly. Luca and Adrian had both decided that they did not need the supplement in order lose the same amount of body fat as Sean and Ricky. Since Luca and Adrian were exposed to the same experimental environment, it was only appropriate to consider them as the control group. All four subjects were on the same exact diet which consisted of oatmeal in the morning, a tuna sandwich and green leaf salad for lunch, and steak with broccoli at night. As for their workouts, they were performed together consisting of the same exact routines. Every workout would begin with running for 10min then cycling for 10min and abdominal workouts at the end of every workout for 10min.
