Extract of sample "Identified Limitations and Threats to Validity"

Internal and external Validity Affiliation Internal and external Validity Quantitative Research Mitchell and Jolley explain that full validity is established by eliminating all threats. Results from the research can then be assumed to represent the reality. Effects observed in the study are a true reflection of reality without any interference by extraneous factor. The study aimed at measuring the impact of CSR on the purchasing behavior of customers. Selection is one threat to internal validity. It was assumed the participants were honest about their purchasing behavior and they understood the questionnaires given. History between the company and the consumers can influence their decisions. Corporate associations determine the information the person holds about the company, which determines the responses given in a questionnaire. The participants were at least 18 years old, and lived in Lima. This selection predisposes the respondents to certain outcomes. Reliability is affected by the stability of collected data. The responses of the recipient are bound to change during different periods. External validity refers to the extent to which the findings can be extended to other areas. The respondents were selected randomly and came only from Lima. Their responses could therefore fail to cover the behavior of customers in other cities and countries (Marquina, 2007).
Questionnaires are effective for collecting large amounts of data. In this case, over 600 customers participated and each answered 32 questions. In this way the researcher was able to collect large amounts of customer views. Correlation between the different sets of data could be used to determine its reliability. However, respondents might not be willing to give responses. The researcher used two interview phases to using the same subjects. This provided more accurate responses.
Qualitative Research
Interviews can be used for qualitative research. A research for CSR utilization in Nigeria used interviews as the source of information. The research method affects the quality of results collected. In this case interviews were used and the interviewer cross-examined respondents for detailed answers. In this way, the researcher collects detailed information regarding the study question. The same interview questions were used, and the previous interviewees could discuss the questions with others. This influenced their view regarding CSR in the country. The environment of the interviewees determines the quality of answers they give. In this case the respondents came from different sectors and the answers given depend on their knowledge about CSR. Respondents were from Glo Mobile, Celtel, Astro Soccer Nigeria, and UBA. The respondents have different interpretation of study questions and methods. Their responses depend on how well they understand the questions, which might not coincide with the real situation. The respondents were drawn from different sectors and had different IQ and interpretation skills. The responses from the interview cannot be applied to all sectors. The respondents were drawn from banks and SMEs. The results are not applicable to telecommunication or manufacturing sectors due to their diversity (Helg, 2007).
The author used different correspondents from different sectors. This broadens the experience and environment of the respondents. At times, respondents might not be willing to give full details. The interviews were also conducted in different areas such as offices and restaurants to expose the residents to different environments and make them more willing to give their comments. The interview process is effective for gathering a wide variety of responses. The interviewer asked several open ended questions to increase the range of possible responses.

.... What the State should do is to keep itself updated regarding the newest models that represent risks for certain diseases. Exposure Assessments Of course, despite the recognition that mathematical models may not identify all the interplaying risks involved and put enough weight on them, everyone should be vigilant in meticulously looking at how the mathematical models were obtained to determine whether they put enough weight to all identified risk factors or not. In my opinion, all mathematical models on exposure assessments should be validated by the researchers themselves, especially if they are to be used in passing laws by the state. Laws should not be based on unfound mathematical...

Threats to Internal and External Validity

...?THREATS TO THE VALIDITY OF AN EXPERIMENT Firstly, we begin by clarifying what we mean by threats to validity. Maxfield and Babble (2005) put it in very simple terms: these are, according to them, “possible ways that a researcher might be wrong in inferring causation. (page 191)” Burns (1997:1) defines validity as, “ the best available approximation to the truth of a given proposition, inference or conclusion. In other words, when we make some claim, does the evidence support our conclusions.”  Factors affecting internal validity ask whether or not the research conditions warrant the conclusions. On the other hand, factors affecting...

External Validity

...Illustrate the importance of controlling for the threats to internal validity, and explain why external validity must be determined once internal validity is obtained. Validity can be described as the possible estimate of the truth of a specified proposal research or conclusion. Validity is extremely important in determining the perfect conclusion of an experiment conducted. Internal validity helps to determine if the conclusion for an experiment is perfect or not. In an experiment all the external factors are also to be considered so that a perfect conclusion is derived. For e.g. in a school a scheme is adopted to...

... in participants that are not evident to both a researcher and a participant. They can however be controlled through precautionary measures such as application of an “equivalent control group” to eliminate the effects on validity (Jackson, 2011, p. 236). Historical effect is therefore an example of validity threats that are not easily identifiable but can be controlled. Reference Jackson, S. (2011).

...and validity are related i.e. closely inter-dependent. Although validity cannot exist without reliability, the latter can exist without validity. Some of the systematic factors that affect both the reliability and validity of measurement include presence of unsystematic events, systematic inconsistency and the change in the event being measured. The unsystematic threats to reliability include subject reliability, situational reliability, observer reliability, instrument reliability and data processing reliability (Klaus, Boyle and Simon, 13). Some of the factors to consider in ensuring reliability and validity include time and money,...

Construct Validity

...Construct validity Researchers create constructs to facilitate measure of variables in studies. The Big Five Personality Test tool is an example of aconstruct and measures personality traits. The construct has a series of structured questions that a participant responds to, and responses are computed, based on predetermined categories, to identify elements of personality traits. Some responses are measured on ordinal scale while other are measured on a nominal scale. Construct validity is the level of accuracy with which a construct measures an element that it is expected to measure. Ability to measure a variable of intention identifies construct...
