All Rights Reserved. The article What is a null hypothesis? A hypothesis is a tentative statement that proposes a possible explanation to some phenomenon or event.
To test whether a operational definition essay is true this web page not, a researcher carries out some kinds of test to see if the hypothesis is backed up by its marking scheme dissertation. An example operational definition essay a hypothesis is: Obesity is due to eating too much candy.
To prove this hypothesis, the researcher might examine data on whether candy is correlated with obesity. However, after reviewing the results, it is possible that any relationship that appears in the data was produced by random chance. Therefore, the researcher must compare the results against the opposite situation; candy does not lead to obesity.
This is known as the null hypothesis -- the assertion that the things the research was testing operational definition essay not related and that results are the produce of random chance events. Null Hypothesis: Obesity is not due to eating too much candy.
Download full paper NOW! Alternate Hypothesis: Obesity is due to eating too much candy. In statistics, the only way of supporting a hypothesis is to refute the null hypothesis. Rather than trying to prove an idea the alternate hypothesis right, the research must show that this web page null hypothesis is likely to be wrong -- the researcher has to 'refute' or 'nullify' the null operational definition essay. The researcher has to assume that the alternate hypothesis is wrong until the researcher finds evidence to the contrary.
Essay on Operational Definitions of Each of These it Assignment A operational definition essay hypothesis is used to prove or disprove that changing one variable has an effect on another variable Non-directional hypothesis. Thus, according to this source, a non-directional hypothesis will contain words like "influence," "change," "alter," and "affect" rather than asking whether the effect is positive or negative.
A non-directional hypothesis would be used when both positive and negative more info are of equal importance in providing evidence with which to test the null hypothesis and in situations where the researcher isn't sure how an experimental group will perform against a control group Hypothesis testing.
Non-directional hypotheses are frequently used in: a political science to weigh opinions of various issues among the people; b economics when studying consumer confidence; c pharmaceutical research to determine if drugs have any affects; and operational definition essay information operational definition essay to analyze data sources and decentralized dataflow Non-directional hypothesis.
Directional hypothesis measures the effects essay conclusion partnership two variables on each other Hypothesis testing. In other words, it measures the direction of variation of two variables. Operational definition essay effect of one variable on the other variable can be in positive direction or in negative direction.
Thus, the use of directional testing is used when assured, argumentative essay swimming will only positive or negative differences are of interest in an experimental study. Validity and reliability are related, but different concepts.
Validity is the extent operational definition essay which an indicator or set of indicators actually measure the concept it represents Methods for social researchers in developing countries. For example, does operational definition essay classroom test really measure the student's knowledge of the subject being tested? Reliability, on the other hand, is the extent to which operational definition essay measuring procedure gives similar results with repeated use with the same respondents Methods for social researchers in developing countries.
For operational definition essay, would an average test score be the same elementary statistics homework similar when carried out again on a comparable test group?
In order for a test to be valid, it must be reliable; but reliability does not guarantee validity. This is because a reliable measure could be measuring something consistently, but not necessarily what it is supposed to be measuring. In the research process, reliability refers to the consistency, stability, and repeatability of a data operational definition essay instrument Intro to research methods. According to this source, a reliable instrument is important because it does not respond operational definition essay chance factors or environmental conditions; it will have consistent results if repeated overtime or if used by two link researchers.
Click at this page understand the importance of reliability, it is useful to understand why research instruments must be reliable in terms of stability, equivalence and internal consistency Intro to research methods as well as general thesis among coders or raters, a concept called operational definition essay reliability Interrater reliability.
A stable research instrument is one that can be repeated on the same individual more operational definition essay once and achieve the same results. Further, with equivalence, the same results can be obtained using different observers at the same time and similar tests given at the same time will yield the same results.
Internal consistency refers to the extent to which all parts of the measurement technique operational definition essay measuring the same concept. For operational definition essay, when developing a questionnaire, each question should provide a measure consistent with the overall results of the test.
Interrater reliability is the extent to which two or more individuals coders or raters agree Interrater reliability. Thus, interrater reliability addresses the consistency of the implementation of a rating system Unreliable measures can cause researchers to draw grounded dissertation conclusions, formulate faulty theories, operational definition essay make inaccurate claims about the generalizability of their research.
Inherent difficulties related to the use of unreliable measures include Difficulties of achieving reliability : Quixotic reliability refers to the situation where a single manner of observation consistently, yet erroneously, yields the same result.
For example, the responses of subjects http://freey8.com/500-word-essay/existentialism-essay-titles.html not always operational definition essay represent their mental or physical state. Diachronic reliability refers to the lack of stability of observations over time.
For instance, when researchers administers tests to the same subjects a year later after the initial test, many confounding variables could have impacted the researchers' ability to reproduce the same circumstances present at the first operational definition essay. Synchronic reliability refers operational definition essay the lack of similarity of observations within the same time frame.
Multiple, but different observations, might simultaneously be true. A case study is a qualitative research method useful at operational definition essay an understanding of a complex issue or object and can extend experience or add strength to what is already known through previous research the case study as a research method. Case studies emphasize detailed contextual analysis of a limited number of events or conditions and their relationships. Read more have used the case study research method for many years across a variety of disciplines; but social scientists in particular have widely used case studies to examine contemporary real-life situations and provide the basis for the application of ideas and extension of methods the case study as a research method.
Other areas that have used case study techniques extensively include government and evaluative scenarios Tellis, As explained by Tellis, the government has carried out studies to operational definition essay whether particular programs were efficient or if the goals of a particular program were being met. Evaluative applications have been conducted to assess the effectiveness of educational initiatives.
In the government and evaluative studies, quantitative techniques tended to obscure some of the important information that the researchers needed to uncover. Further, as explained in the case study as a research method, researchers from many disciplines use the case study method to build upon theory, to produce new theory, to dispute or challenge theory, to explain a situation, to provide a basis to apply solutions to situations, to explore, or to describe an object or phenomenon.
The advantages of the case study method are its applicability to real-life, contemporary, human situations; its public accessibility through written reports and its ability to facilitate an understanding of complex real-life situations the case study as a research method. In case studies, there is a detailed and holistic discussion of the context and operation as well as themes, issues and implications of the operational definition essay or cases.
Statistical methods operational definition essay only able to deal with situations where behavior is homogeneous and routine while case studies can deal with creativity, innovation, and context Case study: Strengths and weaknesses. Another major advantage of the case study is the potential for the development of novel hypotheses for later testing Case study in psychology. The case study can also provide detailed descriptions of specific and rare cases that aren't appropriate for quantitative research Case study in psychology.
In addition, the case study offers flexibility Case studies. Because project design emphasizes exploration and because they have a loose format, researchers are comparatively freer to discover and address issues as operational definition essay arise in their experiments and operational definition essay begin with broad questions and narrow their focus as their work progresses. However, despite their utility, case studies have many disadvantages.
First, and most importantly, the study of a small number of cases provides no grounds for establishing reliability or generality of findings the case study operational definition essay a research method. Therefore, case study research as most see more as an operational definition essay tool.
