...Fundamentals of Research Shannon Ladd April 21, 2013 BSHS/382 Vanessa Byrd This paper will define scientific method as well as give an explanation of how scientific research is used in a human services field. It will also discuss the steps in scientific inquiry and why those steps are important and an example will provide of scientific method in relation to the human services field. A description of quantitative and qualitative research will be given, explaining the differences in both model and how these methods relate to the human services as well as the scientific method. Further discussion will involve quantitative and qualitative research methodology touching on the definition of mixed method research. Finally summarizing how scientifically research sound supports the function of a human services manager. The scientific method is a method for research and study that is applied to investigate observations and to bring answers to questions. Researches can exploit the scientific method to search for cause and effect relationships. There are many different types of aspect to the human services field, no matter which one research is always needed. If there is a sudden increase in homelessness, child abuse, or joblessness, research offering results is required to answer the question that are related to the increase. The path to those answers can only be found through research. Scientific method according to the Merriam-Webster (2010), is “principles...

...Human Service and Research Methods Throughout the numerous human service fields, research is necessary from determining risk to providing solutions. The correct research method increases the ability to make the proper decisions for each situation. The scientific method is one many people learn early in life because this method increases understanding and answers many questions throughout the numerous fields. As a social science many questions need answers, the scientific method assists researchers in discovering these answers. A clear comprehension of the quantitative and qualitative methods allows researchers to know when to use what method. At times both these methods are necessary, knowledge about how and when to incorporate the mixed method is essential. An understanding of the different methods and how they can influence the functions within the human service field is crucial. Scientific Method “The scientific method is the basic method, guide, and system by which we originate, refine, extend, and apply knowledge in all fields,” (Edmund, 2011, What is the Scientific Method, Para. 4). The text (Creswell, 2008, p. 51) sums these stages into six areas of focus; “identifying the research question, reviewing the literature, specifying a purpose, collecting data, analyzing data, and evaluating research.” The scientific method allows researchers to address many common questions, reach beyond other conclusions, and by using empirical reasoning to decide what is true, (Rosnow...

...Individual Correlation Discussion BSHS/382 July 24, 2013 Vanessa Byrd Pearson product Moment is a method that is used often in order to compute any correlation between two variables showing a linear relationship. This could be used to look at how the consumption of carbohydrates plays a role in weight loss. The advantages of using this method are that an individual is able to make predictions when there is information on the correlation. When or if two variables are correlated then predictions can be made based on one variable or the other. A disadvantage of this is that even though correlation is similar to causation it does not determine the cause and often times that is forgotten. This helps to determine that there is a relationship between the variables but it cannot determine the cause. This can only be applied of the variables are not dichotomous. Spearman Rank Correlation is the most popular method used with non linear correlations and just like Pearson's it measures the relationship between two variables. Because the data used is in the form of ranks the correlation will continuously remain the same. The disadvantage is that this method is best used for data that is continuous and normally distributed which creates the ranks and cannot be used with actual data. This form could be applied when looking at test scores or a business’s monthly reports. Point-Biserial Correlation is used to estimate the degree of the relationship between a natural occurring dichotomous...

...Wk: 4 Correlation Response Paper Stacy Harris BSHS/382 0ctober 31, 2011 University of Phoenix Staci Lowe Correlation Describe at least two different methods of establishing correlation between variables and provide an example of each. According to the text, “There are four forms of Karl's Pearson's product-moment r. They are Pearson r, Spearman rho (rs), Point-biserial r(pb), and phi coefficient. Each method views variables not in isolation, but instead as systematically and meaningfully associated with, or related to, other variables. For example, using correlation coefficient which indicates the strength of association between two variables the (X,Y). it also describes correlation that reflect mutual relations between X and Y resemble a straight line also known as linearity. In addition, values of r of 1.0 (positive or negative) indicates an perfect linear relation, while 0 indicates that that neither X or Y can be predicted by a linear equation. In these types of cases when the r is positive then there is an increase in both X and Y. but if the r is negative its only an increase in the X and a decrease in Y. Another method that's commonly used is the dichotomous variable also known as the discrete variable which has two separate...

...Fundamentals of Research University of Phoenix Karan Normand BSHS 382 March 14, 2012 Staci Lowe Fundamentals of Research Research makes many things possible in life. Business owners use research for marketing purposes. Consumers use research for the best purchases and so on. The scientific method is considered the most effective way to test data. “Research is a process of steps used to collect and analyze information to increase understanding of a topic or issue” (Cresswell, 2008). Scientific Method The scientific method is a method of investigating. The scientific method is done in steps starting with defining a question. One need to understand exactly what it is that is to be examined. Otherwise the direction of the experiment is chaos and no determination of the research can be made. The next is to make a guess or develop a hypothesis as to what is believed to be found during the research. Then we need to gather the data so we have some information to go by. This can be done with surveys, testing, or any resources that can give the necessary information. The next step is to test the hypothesis. It must be logical and unbiased for the experiment to be accurate. The conclusion is based on the design of the experiment and the results. It may or may not agree with the hypothesis. Human Services can use the Scientific method to research homelessness in a certain area. For this project a mixture of quantitative and qualitative research should be considered...

...Research Article Written Critique #1 Dolores Williams BSHS 382 Dr. Ruth Bundy March 16, 2010 Research Article Written Critique #1 To quote an old African proverb “It takes a village to raise a child.” Children will thrive only if a society cares enough to support families. A family alone, a health worker alone, a therapist alone, a social worker alone is unlikely to achieve the success that may be possible through involvement and coordination of the community. Recognition of the importance of brain development in the early years of life has led to expanded early intervention programs for very young children with or at risk for developmental disabilities throughout the world (National Dissemination Center for Children with Disabilities, n.d.). Developmental milestones are behavioral indicators of underlying processes. If developmental milestones are used as a curriculum guide without consideration of the underlying processes, infants will develop splinter skills rather than a solid foundation for learning (National Dissemination Center for Children with Disabilities, n.d.). Recent developmental brain research suggests a plausible biological basis for early intervention. However, specific intervention practices must be evaluated on their efficacy, effectiveness, and cost justification. Early intervention has made important shifts in emphasizing social competence in the child and the essential role of the family and community (National Dissemination Center...

...Fundamentals of Research Anna Albright BSHS/382 May 19, 2014 Fundamentals of Research Describe the Scientific Method The scientific method is compiled of a standard set of techniques that can be used to increase knowledge by making valid observations, interpreting results and simplifying those results. By using the scientific method researches are able to tests pre-existing results as well as modify and refine them or open up prior research for debate. According to Anol Bhattacherjee “the scientific method must satisfy four characteristics: replicability, precision, falsifiability and parsimony.” (Bhattacherjee, 2012) The definition of replicability is in the word meaning the research should be able to be replicated or repeated by other researchers and yet acquire similar or the same results. Precision means that although theoretical concepts can be difficult to measure they must be explained with intense precision that other researchers will be able to use the same explanations to measure the same concepts and test that same theory. According to Anol Bhattacherje “ the definition of falsifiability is that a theory must be stated in a way that it can be disproven. Theories that cannot be tested or falsified are not scientific theories and any such knowledge is not scientific knowledge.” (2012) If a theory consists of ideas that are not accurately measurable or cannot be tested it cannot be deemed as scientific. “Parsimony occurs when there are multiple explanations...

In this paper there will be a definition of the scientific method and how it relates to the human service field. There will a discussion of the steps in the process of scientific method along with why the steps are important to the human service field. The terms qualitative and quantitative research will be defined and discussion on how they differ, and they relate to the human service profession. Mixed method research will also be discussed and when it would be a good time to apply this method in human services. Finally a brief summary will be included, in which research will support the function of a human services manager. Scientific Method The use of scientific method is essential in the human service field. When using the observing ad experiments method a human service worker can understand and learn much more information about his or her client. The scientific method is defined as method of investigation, which a problem is identified first and observations, experiments, or other relevant data is useable to test or construct hypotheses to solve a problem (Creswell, 2008). The following step of the scientific method consist of first identifying the research...

...Reliability and Validity Carmen Kbeir BSHS/382 March 26, 2012 Edessa Jobli Reliability and Validity Researchers employ a wide range of data collection methods to obtain information. Some of these methods are quantitative, such as experiments. Others are qualitative, like field studies. Within each of these methods are specific procedures that lead the researcher to various outcomes. The tools, or instruments, used to measure observations or statistics throughout the process are very important. To understand how well the instruments work and the extent to which the outcomes will produce similar results in the future, researchers examine different types of validity and reliability. Reliability is the extent to which an instrument produces consistent results and the probability that others can achieve the same results when reproducing the study. There are several types of reliability, including alternate-form reliability, internal-consistency reliability, item-to-item or judge-to-judge reliability, and test-retest reliability (Rosnow & Rosenthal, 2008). Internal-consistency reliability measures the amount of correlation between items on a test (Darity, 2008). The average correlation between items is indicated by item-to-item reliability. These types of reliability let the researcher know how well the items on a test go together (Rosnow & Rosenthal, 2008). A questionnaire or survey is not of much use if the questions on them are completely...

...Reliability and Validity Walter Boothe BSHS/382 April 23, 2012 Staci Lowe Reliability and Validity In human services, research and testing is conducted in order to provide the most effective program possible. Testing methods should have both reliability and validity. They should be both consistent and specific. This paper will discuss two types of reliability and two types of validity and provide examples of how each can be applied to human services research. Additionally, this paper will discuss methods of gathering data in human services, and why it is vital that these methods have reliability and validity. Reliability Reliability refers to the consistency of a measure. A test is considered reliable if we get the same result repeatedly (Cherry, 2010).Regardless of the reason for testing administering a test , in order for it to be reliable , the results should be approximately the same each time it is administered. Unfortunately, it is impossible to calculate reliability exactly, but it can be estimated in a number of different ways (Cherry, 2010). Two specific types of reliability are inter –rater reliability and internal consistency reliability. Inter –rater reliability is assessed by having two or more independent judges score the test (Cherry, 2010). The scores are compared to determine the consistency of the rater’s estimates. One way to test inter-rater reliability is to have each rater assign each test item a score (Cherry, 2010). Next, test administrators...
