Outside of statistical research, reliability and validity are used interchangeably. Generalizations guide researchers to make both correct and incorrect inferences regarding cause and effect relationships that affect various phenomena they intend to study. Riege, AM 2003, ‘Validity and reliability tests in case study: a literature review with hand on applications for each research phase’, Qualitative Market Research: An International Journal, vol. (2019, June 9). Therefore, research studies should be conducted in a manner that allows findings to be interpreted in different management and business contexts. Any scientific research design only puts forward a possible cause for the studied effect. Reliability and validity are two important concepts in statistics. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways. In addition, the researcher needs to note other non- sampling errors in questionnaire design which may affect the quality of responses he obtains. 2. They need to interpret different theories within existing business and management frameworks to find out their true impacts. Validity, reliability and generalization are important concepts in business and management research. IvyPanda. Therefore, a study conducted should be analysed and critiqued by different scholars to find out the credibility of arguments it advances. Modern management theories have demystified many assumptions that are related to business practices which are observed in various environments (Riege 2003, p. 75). VALIDITY AND RELIABILITY 3 VALIDITY AND RELIABILITY 3.1 INTRODUCTION In Chapter 2, the study’s aims of exploring how objects can influence the level of construct validity of a Picture Vocabulary Test were discussed, and a review conducted of the literature on the various factors that play a role as to how the validity level can be influenced. Other researchers must be able to perform exactly the same experiment, under the same conditions and generate the same results. Moreover, it is important for a researcher to find out specific theoretical concepts that are important to his study and how they affect the credibility of results obtained. results: In case you get to calculate reliability and validity, ensure these values are stated together with the results attained. Before designing the questionnaire, the researcher needs to understand the manner in which survey estimates are going to be tabulated. As a result, this allows researchers to use different approaches to predict and measure different variables. The role of validity, reliability and generalizations in questionnaire design needs to highlight important factors that underpin Human Resource Management research in an academic setting.

In management and business research, researchers must be ready to defend the methodologies they use to come up with different conclusions and findings (Cornelissen & Thorpe 2004, p. 3). The final number of respondents chosen should represent all the other students in the institution. Without reliability and validity researchers results would be useless. An effective research process needs to focus on situational factors that impact on the information gathered from respondents. Control groups and randomization will lessen external validity problems but no method can be completely successful. Before the questionnaire is done, it is important for effective sampling techniques to be used to determine the nature of the respondents. "Validity, Reliability and Generalization in Research." It must be noted that modern business research is applied in an environment characterised by constantly changing management practices which threaten the relevance of previous bodies of knowledge gathered through research. What methods/ tools can you use to ensure the validity of the research instrument. Furthermore, this helps him to understand beforehand the quality of responses that he expects to obtain through his study. Reliability alone is not enough, measures need to be reliable, as well as, valid. In different contexts, research is a clearly defined process where different elements and are studied, analysed and presented to show new approaches that increase knowledge regarding a particular phenomenon. Reliability and validity are two important considerations that must be made with any type of data collection. The time in which the survey is going to be conducted has a direct consequence on the results attained from the study. Before using the questionnaire survey, the researcher needs to look at other problems which are likely to occur as he carries out his work. 36 no. This problem can be eliminated through using appropriate and easy to understand language in the questionnaire (Mohrman, Gibson & Mohrman 2001, p. 365). More importantly, validity, reliability and generalisation allow deductive reasoning by a researcher to ensure all steps of his study state specific implications that are likely to be realised. This makes it possible for a researcher to investigate different aspects of reality thoroughly, to come up with new theoretical findings that add value to the study (Vincent, Bharadwaj & Challagalla 2005, p. 11). Reliability is an important concept in management research. We utilize security vendors that protect and Therefore, it is important for researchers to understand the link between theory and practice and how these two concepts impact on management discourses.

This approach will help a researcher to come up with a more accurate sample that comprises of students drawn from all statistically relevant sub-groups. For example, if you are performing a time critical experiment, you will be using some type of stopwatch. In addition, researchers need to gradually shift from a perception influenced by multiple perspectives to one influenced by methodologically proven concepts to strengthen their arguments (Cornelissen & Thorpe 2004, p. 13). A test is valid if it measures what it’s supposed to. Establishing validity and reliability in qualitative research can be less precise, though participant/member checks, peer evaluation (another researcher checks the researcher’s inferences based on the instrument (Denzin & Lincoln, 2005), and multiple methods (keyword: triangulation), are convincingly used. They need to use techniques which accurately capture the viewpoints of different sources of information they use in their studies. Debate between social and pure scientists, concerning reliability, is robust and ongoing. Reliability and validity of research. He also needs to find out if his sampling techniques stratify the targeted population effectively (Mohrman, Gibson & Mohrman 2001, p. 362). professional specifically for you? Many researchers move from the known to the unknown concepts in their quest to uncover new information regarding a particular phenomenon (Cornelissen & Thorpe 2004, p. 9). Since most of the participants in such a study are likely to be students, a researcher gets an opportunity to investigate their understanding about real world application of HRM principles. Objectivity in research questionnaires allows respondents to contribute their answers accurately. As a result, a researcher takes time to look at different theoretical interpretations of the topic he seeks to study and their relevance. Reliability and Validity are important aspects of research in the human services field. Since HRM consists of many concepts, questionnaires should be brief and clear to ensure they elicit valid responses from participants.
