Social Inference

We conduct an independent sample t-test using Excel, and obtain the following output (see t-test-height)

The TASIT is designed to assess disorders in social cognition using real-life stimuli in the form of videoed vignettes of professional actors engaged in conversation. It was initially developed with people with traumatic brain injury (McDonald, Flanagan et al. 2003) but has also been used in adolescents (McDonald, Fisher et al. 2015) and older people (Burdon, Dipper et al. 2016), people with different types of dementia like Alzheimer’s disease (Henry, Ruffman et al. 2008) and frontotemporal dementia (Kipps, Nestor et al. 2009, Rankin, Salazar et al. 2009). The TASIT-R includes three parts assessing basic emotion recognition through to the ability to grasp aspects of communication. There are two alternate forms for the entire test and Form A was used for this study.

Based on the given sample of student test scores of 50, 60, 74, 83, 83, 90, 90, 92, and 95 after rearranging them from least to greatest. As the mean is based on the average of sum, the average of this sample is 79.67 or 80. The mode refers to numbers that appear the most in a sequence and in this case 83 and 90 both appear twice. Range calculates the difference between the largest and smallest number, which are 95 and 50 which have a difference of 45. The variance is the difference between the sum of squares divided by the sample size, which is the number in the sample minus one (Hansen & Myers, 2012), meaning it takes each number of the set and subtracts

At one school, the average amount of time that tenth-graders spend watching television each week is 18.4 hours. The principal introduces a campaign to encourage the students to watch less television. One year later, the principal wants to perform a hypothesis test to determine whether the average amount of time spent watching television per week has decreased. Formulate the null and alternative hypotheses for the study described.

C. The researchers analyzed the data as though it were at the interval/ratio level since they calculated means (the measure of central tendency that is appropriate only for interval/ratio level data) and standard deviations (the measure of dispersion for interval/ratio data) to describe their study variables.

My hypothesis is that social influence theory and groupthink play a significant factor in the actions seen at the professional, college and high school levels which can result in irrational and dysfunctional behavior. We see athletes on television and at local sporting events influenced by what they see and hear in social media and within their community. Thus, these individuals are influenced by social influence theory and groupthink with or without their cognitive knowledge.

The study consisted of fifty, female, undergraduate college students. The ethnicities that were use for this study were African American, European, Asian, Hispanic, biracial, and a very slight percentage was categorized as other. The experiment would begin at 5:00pm everyday, for four weeks. One of the three groups was administered each day. The three groups were either peppermint, expectation, or control. Each participant was seated down, given an instruction sheet, a laptop, and was not able to see the other participants from their view.

The analysis of the data was done by employing the following statistical techniques which were chosen only after the investigator found them to be most appropriate and compatible to the data. Each statistical method is based upon its own specific assumptions regarding the nature of the sample, its universe and research conditions. These factors were considered in advance. Following statistical measures were

We conduct an independent sample t-test using Excel, and obtain the following output (see sheet T-TEST)

The mean, average of the population, the standard deviation, deviation in the sample, and a histogram, a graph to show the percentage of the population, was prepared. The means calculated as follows: blue 0.2072, orange 0.2271, green 0.1852, yellow 0.1165, red 0.1448, and brown 0.1192. The histogram was bell shaped with three outliers, numbers outside the given range, of 55 candies, or one bag.

The results from this study only reflect a very small number of the population, so it is difficult for this experiment to show any significant results. It would have reflected better on the results if the sample size had been meet, however it was not possible due to lack of time and number of eligible volunteers.

“Social influence is the process by which the actions of an individual or group affect the behavior of others” (Feldman 495). These influences are strongly experienced by members in the group. Every group is unique and is mostly guided by a particular norm and behavior. An individual in a group passively or actively allows himself to be influenced by the group just to have a sense of belongingness. In the bid to prevent being excluded or rejected from a group, some individuals overtly adhere to the norms of the group. “Thus, people conform to meet the expectations of the group” (Feldman 495).

On the other hand, informational social influence involves situations where an individual may choose to agree with others, especially the majority, due to high levels of trust that the majority have more social power through information and knowledge regarding a particular issue as compared to the individual on him/herself. In addition, in situations of crisis, people also tend to associate and exhibit
