One of the main reasons this research was conducted was to understand how multitasking on your computer during class affects the student and his/her peers around them. This research is very topical, considering that technology is becoming extremely prevalent in our everyday tasks. The results of this study provided that multitasking does have consequences on the student and their peers (Sana. F., Weston, T., & Cepeda, N. J., 2013). To begin with, the study proved that learning and understanding

Imagine that you are going to design and perform the experiment described in the dialogue. 1. What is the hypothesis that will be tested in the experiment? If the milk is added to the cup before the coffee is, then the model will be able to tell the difference in flavor 9 times out of ten. 2. Why is it important to offer the model more than just two cups (one with the milk added first and one with the milk added second)? Explain your answer. I believe it is important to offer more than one cup
Introduction. Clients with substance abuse issues are growing at a high rate. These clients can come in to an environment where they are told to go seek treatment for their substance abuse, or they are not even told to seek treatment but they do anyway. The clients that are less motivated are often thought of as people that do not care and so they are pushed aside from those that are willing to come to treatment. This paper is going to focus on engaging clients who have a substance abuse diagnoses
The nationality of the antebellum slave is difficult to define. The original slaves were of African descent, and so, one could argue that the great continent of Africa is the source of their nationality. However, even if this were the case, this provision only encompasses the first generation of Africans bound by American slavery. Well, what about the slaves that were born in America? If one were to consider the principle definition of nationality: “the status of belonging to a particular nation
competition may lead to a higher level of political participation, and will explain problems that may arise when studying this theory. Thus the paper looks at the potential of reverse causality and confounding variables while still explaining the theory. The paper concludes that the due to confounding variables the relationship was not as strong as originally though, but there is still a relationship despite that. To begin I will show why this is worthy of study. It seems like political participation
during handoffs will increase the adequacy and completeness of the information communicated from nurse to nurse. In this paper I discuss the development of the research question I have proposed for my Capstone Proposal Project (CPP), extraneous and confounding variables pertaining to the project, and my proposed strategy problem solution. Development of the Research Question For my CPP I have projected to discover the answer to this particular research question that I have developed: Does having experience
Smiling is an important function in expressing your emotions of happiness, amusement, affection or pleasure. It is often thought that you smile because you are happy however it can go the other way as well; you can feel happy because you’re smiling. Parede, Stavraki, Brinol, & Petty (2012) administered an experiement looking at the Impact of facial expressions (smiling) on attitude change. It was hypothesised that ‘smiling would be associated with greater reliance on thoughts than no smiling informing
The scientific method is built on the principle that nothing can ever be proved as definitively true. Rather, once a hypothesis is proposed, evidence can be generated in favor of the hypothesis or in favor of an alternative hypothesis. When enough evidence is gathered in one direction or the other, the original hypothesis is either accepted or debunked in favor of an alternative. As scientific work is always in flux, any previously accepted theory can always be overturned by new evidence.1, 2 Many
Studies on Opioid Abuse: Confounding Variables and Future Research Peer Reviewer: Alize Hassan Limitations: A retrospective cohort study found that there was a causal relationship between previous drug abuse and opioid abuse when opioids are used for chronic pain management. Therefore, the study determined previous drug abuse as the most significant risk factor regarding potential opioid abuse with a relative risk of 3.3.1 However, the study made no mention in its “methods” section of corrections
Moreover, the dependent variable, the variable to be measured, of the study was the degree of emotional response of the strangers that were approached. In addition, the study might include confounding variable, which are the cultural background of the strangers, and the mood of strangers of the time. The confounding variables should be controlled as they might affect the dependent variable. The operation of the experiment was I walk up to a stranger and put on different emotions on my face, and observe
direct correlations between length of stay & more nursing time at the bedside have been established (Chan et al., 2011). Confounding Variables Without participating in a longitudinal study, it is difficult to truly assess the efficacy in mandating nurse staffing ratios. It is difficult to measure the benefits of mandated staffing due to numerous confounding variables. These confounding variables include the resources available at specific hospitals in addition to the populations that they serve. Hospital
1. Explain in a short paragraph what you understand by the term “reliability”. (2) a. Reliability means that a rater or instrument is consistent and reliable in their measurements from trial to trial. When a measurement is reliable it can be reproduced over and over again and still consistently be free from error. However, it is impossible for a measurement to be completely free of error. Therefore, it is important that the measurement error is calculated. This is the difference between the observed
ANOVA = Analysis of variance = a statistical model for comparing means. Interaction = within the context of ANOVA, this is when the effect of an IV on a DV varies as a function of another IV (see ANOVA footnote 1 example). Confounding [variable, element—p.778) = a confounding variable is an extraneous component within the experiment that correlates with both the independent and dependant variables and influences the interpretation of the relationship between the targeted variables studied. It also
In the research article “OBEY AT ANY COST”, Stanley Milgram conducted a study to examine the concept of obedience and composed disturbing findings. Milgram’s findings on obedience were considered one of the most influential and famous works in the history of psychology. His examination on obedience was that people were possibly capable of doing abuse to other individuals by being demanded to do so. Milgram pertained this to World War II and the inhumanity that has been bolstered and the barbarity
carcasses infested with ticks may cause Lyme disease but requires further investigation. In conclusion, occupational exposure to ticks was associated with an increased risk of Lyme disease seropositivity in outdoor workers after control for multiple confounding variables. Personal preventive practices play essential role in Lyme disease prevention such as wearing long-sleeves and avoiding contact with tick exposure areas. The insect repellent use and prophylactic antibiotics should be assessed for clinical
A common topic in college and even in high school is GPA. Needing a certain GPA to get a specific program, stressing over exams so one’s GPA does not drop, or retaking classes to bump a GPA. However, what does receiving an A really mean? Was earning an A back in 1995 the same as now? Jordan Ellenberg, an assistant professor of mathematics at Princeton University, addressed the controversy of grade inflation in the article, “Don’t Worry about Grade Inflation.” Grade inflation is when more students
analyzing the literature that included couples and parents of more gender configurations than what is typically represented. Researchers acknowledged the shortcomings of stereotypes and previous research done such as confounding family structure with gender. This is a frequent confounding variable when researchers compare child outcomes from single mother households to heterosexual parent households to argue that fathers are necessary for child rearing. They individually broke down any strengths or
take place in the participant's natural environment and consequently are easier to generalise. However, this arguably comes at the cost of internal validity. Researchers have less control over variables in a field experiment and this may lead to confounding variables also impacting the
The purpose of an experiment is to systematically test and prove, or to test and disprove a hypothesis. This is accomplished by collecting evidence, observing the effect of variables, and measuring the results. An experiment is a controlled event used to objectively observe phenomena where one or more variables are used to interact with a constant variable. The researcher observes the outcome of the constant variable on the other variables. The experimenter is interested in establishing causality
