In a clinical trial, 10 subjects were to be divided equally between the experimental drug and the placebo. How many ways can they be assigned? The way to solve this question is 1x2x3x4x5x6x8x9x10/ (1x2x3x4x5) (1x2x3x4x5) That’s mean 3,628,800/14,400…
Throughout the trial, those who were responsible in reading and monitoring the results were also double blind; they did not know whose results were the true experimental group and who were a part of the placebo…
a) A political pollster reports that his candidate has a 10% lead in the polls with 10% undecided. Observation as he is only guessing as to the conclusion that will overcome the final analysis. Observation is the presence of observing only where the experimental is adding to or taking from. 5) Select the study that is most appropriate and EXPLAIN WHY it is most appropriate for the study.…
The experiment consists of two parts. First, we need to randomly select children from low income families and randomly assign them into two groups: A and B, recording their fitness like BMI data. Second, we have to manipulate one and the only one independent variable which is the presence versus the absence of exercise and measure the dependent variable which is the children’s BMI data. To be specific, we keep one group of children do exercise every day and another group be more sedentary as well as control all other conditions or variables equal. Also, to avoid the experimenter expectancy effect and the placebo effect, we should let other researchers assign the groups without knowing which one is the experimental group or control group by ourselves.…
Subgroup analysis (Table 2) Concomitant Hydroxyurea use • Patients taking concomitant hydroxyurea in the high dose Crizanlizumab group were found to have a median of 2.43 pain crises per year. When compared to the concomitant hydroxyurea placebo group this was a 32.1% lower rate than placebo. • Patients in the high dose Crizanlizumab group who did not receive hydroxyurea were found to have a median annual crisis rate of 1.00. This was found to be a 50% reduction compared to the placebo group who also did not receive concomitant hydroxyurea…
The system of segregation was a law that separated the races. Many Southerners were upset that the former slaves had the same rights as everyone else after Lincoln declared them emancipated. The first Civil Rights Act passed in 1875 gave African Americans rights to be treated fairly in public and on public transportation. Ultimately, the court passed the Jim Crow laws separating the races in the South. In 1890, Louisiana had a separate car law that passed for black and whites.…
Group A received the power pill and 60% of them saw results. Group B received the pill and 7 out of the 10 saw results. Group C was given the placebo and 5 out of the 10 saw results. Group D was not told about the effect 4 out of 10 of them saw results. Groups B and D did not receive information.…
There are 3 key variables to consider when working with crises. Them being (1) crisis structure, (2) deep mistrust, and (3) groupthink. Crisis structure is determined by “the behavior of the participants and their comparative balance in power and interests at stake.” How escalation occurs and the actions brought forwards seems to depend on what is viewed as an important factor or the “hostile manner” a state acts in acts of freedom. Mistrust occurs when the wrong action is taken or an action that could have been taken sooner but was overlooked or not known because of the decisions made leading to result.…
Phenylthiocarbamide (PTC) is an organic compound that contains crystals. The molecular formula of PTC is C7H8N2S. The ability to taste PTC is a dominant trait. A chemist named Arthur Fox was the first person to observe the different taste reaction to PTC (Wooding 2006). In 1931, Arthur accidently blew powdered PTC into the air and his coworker believed that it was bitter. When Arthur tasted the PTC, he tasted nothing at all.…
For this experiment, the groups would have to be reasonably large in order to increase reliability. In the correlational design study in the newspaper article, causation cannot be inferred because of the key statistical principle “correlation does not equal causation.” In order to determine causation, a double-blind experiment must be conducted. The results of the double-blind experiment would be the true indicator of any cause-and-effect relationship between taking vitamins and crime…
Can groups be too open, or, too closed? In chapter two of the textbook: In Mixed Company: Communicating in Small Groups and Teams (2013), it is affirmed that groups can be too open, or, too closed. A group may start out with the perfect balance of membership skills and knowledge to fulfill its’ goal; however, in time that will change.…
Introduction The Placebo effect, sometimes referred to as “sham effect,” is an advantageous effect produced by a fake treatment. It focuses on the minds ability to trick itself by using the individual's belief in that treatment. If the individual believes that a treatment will work, it can begin to seem as if it is actually working, and or actually work. It is seen more often than one would think and is normally associated with placebo pills and shots. These placebos do not contain any beneficial medications or vitamins that could affect your health and typically contain things such as water or sugar.…
The society, we live is divided because of many factors, like race/color discrimination, division of religion, and politics. The division of people based on two radically different views, drive people apart. The world is divided because people tend to have different ideas and thus causing division between groups. It will obvious that there will be disagreement in the world, but the problem is that people are not willing to share ideas to make the most ideal option that benefits everyone. The problem is everyone want their way to be the best option because it best accommodates their life.…
Groups survive because of the members! This includes the group leader and all participants in the group. With that said a group must come together and for a bond. Northen states “When groups are not able to develop the cohesiveness that motivates members to remain in the group, the result is that the group disbands, either by decision of the members or simply because members stop coming.” As various personalities make up the memberships of a group there are various challenges from group member roles a group leader may face.…
The flurry of contradictory directives in modern society has forced many women to take on a primarily unconscious defense mechanism called “Splitting”. Splitting is the psychological phenomenon that involves thinking in only one dimension, dissolving all issues into a binary set of conclusions. When a woman ‘splits’ her thoughts, she resolves internal conflicts by rendering them down to one path or desire. This is achieved through the suppression of all other contradictory desires. However, “splitting makes young women feel that their options are limited rather than expansive” (Bell).…
