NRSv433 WEEK 4 DQ4-1 Extraneous variables may have an influence on the dependent variable. In what ways do researchers attempt to control extraneous variables? Support your answer with current literature. Extraneous Variables are undesirable variables that influence the relationship between the variables that an experimenter is examining. They exist in all studies and can affect the measurement of study variables and the relationships among these variables.
Critique on Do Video Games Kill? This article “Do Video Games Kill” by Karen Sternheimer addresses the wide spread idea; video games are the cause for “young killers” (210). Sternheimer believes concern for the influence video games may have on youth is spiraling out of control. She put most of the blame for this out of control concern on the media. She also writes some about politicians and the Juvenile Justice system.
There are various models used in outliers. The interpretability of an outlier detection model is extremely important from the perspective of the analyst [2]. It is often desired to regulate a specific point as an anomaly in terms of its performance with other data. It provides the hints to the analyst about the diagnosis required in an application specific scenario and this is also referred as the intentional knowledge about the outliers [11]. Figure 4 displays the different outlier detection models.
A lab experiment is different as it is in a controlled environment with control over the independent variable as well as all confounding variables, the dependent will be being measured. A experimental is usually designed so that there is a control group and experimental group/s. A change is introduced to the experimental group but not the control. The control group gives the researcher a baseline against which to judge
Quantitative research and qualitative research are research methods that gather different types of data. Qualitative research at its core gathers non-numerical, diagnostic, and/or interpretive data (Experiment Resources, 2012). Quantitative research mainly gathers numerical data or data that can be measured (Experiment Resources, 2012). Each of these research methods describes different types of data and have different goals in their research (Experiment Resources, 2012). Qualitative and quantitative research use different tools for gathering data and tend to approach the data differently (Experiment Resources, 2012).
Running head: DOES VIOLENCE IN MEDIA AFFECT CHILDREN’S BEHAVIOR? 1 DOES VIOLENCE IN MEDIA AFFECT CHILDREN’S BEHAVIOR? Analytical Report Marjorie Gaines April 8th 2012 DOES VIOLENCE IN MEDIA AFFECT CHILDREN’S BEHAVIOR 2 ABSTRACT Decades of research have demonstrated that exposure to violence on television can cause increases in aggression. The recent emergence of violent video games has raised new questions regarding the effects of violent media. Recent research has shown that connections between children playing violent video games can cause later aggressive behavioral problems.
In other words, they answer the question What drives behaviour? It is important to remember that the following are theories, none of which have been conclusively shown to be valid. Nonetheless, they are helpful in providing a contextual framework for dealing with individuals Process theory is a commonly used form of scientific research study in which events or occurrences are said to be the result of certain input states leading to a certain outcome (output) state, following a set process. Another theory that attempts to explain human behavior is Content theory. Process theory holds that if an outcome is to be duplicated, so too must the process which originally created it, and that there are certain constant necessary conditions for the outcome to be reached.
Ahmed 1 Sami Ahmed Professor Grannis English 112 7 December 2008 The Medias Affect on Teenagers The rise of violence and sexual activity in teenagers has placed the entertainment industry under scrutiny. Parents blame the industry for exposing their children to inappropriate content at a tender age. The industry has argued that the rating system at place should give the parents control over the content viewed by their children. Now let us find out whether the content of the media has an affect on teenagers? Or if it is the parent’s responsibility to regulate what teens watch?
Unfortunately, many of today’s television programs are violent. So does TV influence kids that violence, drugs, alcohol and sex are ok? How much violence, drug references, alcohol usage, and sex references does the average American child come across? How much of this do they take in? Hundreds of studies have found that children and teenagers that watch television may: • Become “immune” or numb to the horror of violence • Gradually accept violence as a way to solve problems • Imitate the violence they observe on television; and • Identify with certain characters, victims and/or victimizers Also, Extensive viewing of television violence by children causes greater aggressiveness.
In the movie, they gather to fight not out of spite or hatred for each other but because fighting is a common medium of release for them. Various studies conducted state a direct correlation between the aggregate of time spent watching violence portrayed in media, the television in specific, to aggressive behaviour in adulthood. Aggressive behaviours in children are also observed to increase when they are exposed to violent media because they seem to take it as an encouragement of sorts, because new forms of aggression are brought to their notice. The Tasmanian Devil in Looney Toons and Baby Looney Toons is an example of a violence in children’s entertainment.Berkowitz says that a number of different aversive stimuli, frustration for example, may initiate aggressive responses but aversive stimuli alone do not by themselves orchestrate aggressive behaviour; they simply bring about a readiness for aggressive action. Only if appropriate aggressive cues are present as environmental stimuli, will such conduct surface.
