Reliability and Validity Dede Kendrick BSHS/382 January 16, 2012 Angela Heads Reliability and Validity Evaluating human services is a task that can be very complex. People can have different interpretations of the same event. Another concern is that people are not always honest. Therefore, human services will gain from effective, high quality evaluations of data collection methods. This requires that the data collection methods supply accurate and dependable information. This paper will
A research paper is only considered valuable if it is both valid and reliable in measuring the constructs that it claims to. This paper is aimed at evaluating the validity and reliability of the research paper titled “A Contemporary Analysis of Accounting Professionals’ Work-Life Balance” by Buchheit, Dalton, Harp and Hollingsworth, published in the Accounting Horizons Journal in March 2016 in its first issue of volume 30. The research paper endeavoured to provide answers for two main research questions
According to the 2014 edTPA Administrative Report some random sampling was done for scorer reliability with very positive results. Out of 1,808 portfolios (which were double scored independently) the scorers assigned either the same or adjacent scores with total agreement in nearly all cases (93.3%). While that speaks well for the scorer reliability, as far as appropriate sampling for validation and norming the edTPA appears to fall short. There are several mentions
importance because as the data obtained from the research can be used to form the basis in quantitative research. Several researchers have criticized the fact that qualitative research does not have a method that can be used to measure its quality. However, there are various concepts that can be used to measure the quality of qualitative research. These methods are the school of thoughts of Dixon-Woods et al. and the Lincoln et al. and the measurement of reliability, validity, and generalizability
and confidence values (CI) in establishing the significance of the results assists in enhancing the reliability and validity of the study. Whereas, Tobiano, Chaboyer, & Mcmurray (2012) adopted thematic analysis in data analysis, which facilitated flexibility while maintaining research rigor. The straightforward nature of the thematic analysis also contributes in enhancing the validity of the provided evidence. In the case of Sand-Jecklin & Sherman (2014), the presentation of the findings in terms of
When studying personality psychology, a researcher uses theories, methods, and relies heavily on ethics, reliability, and validity. Using the “LOTS of data” acronym, personality researchers gather information to study people. These include, L-data (life record data), O-data (observation data), T-data (Test data) and S-data (self-report data). (Cervone & Pervin, 2013) Each method has strengths and weaknesses. As well as “LOTS”, researchers must form a theory to “decide what to measure and how to measure
3.1 Introduction Kumar (2014) defines research methodology as the process used to collect data and information for the purpose of analysis and decision making. This chapter will discuss the philosophical foundations of the research which will explain the ontological and epistemological stance underpinning the study. It discusses the mixed-method design and the specific qualitative and quantitative methods adopted and how these challenges were resolved. 3.2 Research paradigm Corbetta (2003) defined
Primaty data from the respondents will be collected using an in-depth interview schedule. This method allows for personal interaction between the respondents and the researcher. It is also ideal as it enable the researcher to vary the questions and also seek for further details from the respondent as may be appropriate (Blumberg, 2008). Secondary data will be collected from journals and book reviews of the strategies the multinational pharmaceutical companies apply to overcome the challenges from
If validity information is reported, which validity approach was used? Was this method appropriate? Does the validity of the instrument appear to be adequate? (4 points) Yes, validity information is reported. Japanese version of 23 –item NAQ-R was used in the study. Abe & Henly (2010) states that “one author and two other nurses with at least
Validity In research paradigm, validity and reliability are the most basic characteristic issues used in qualitative and quantitative analysis. Validity as a psychometric standard is embedded in a positivist approach, which is relevant in reflecting on the qualitative point of view ascribed to the establishment of the truth. In view of this, definition of positivism ascribe to a theory systematic to validity. Additionally, other empirical conceptions culminating from resided validity include
