As a result, the questionnaire is able to capture behavioural as well as personality issues that are likely to influence respondents’ bias and attitudes (Tsang & Williams 2012, p. 11). In effect, a researcher is able to use suitable methodological tools and sampling techniques which have worked well in previous research studies to conduct his own study (Tsang & Williams 2012, p. 7). These two concepts are validity and reliability. Since the questionnaire will mainly target HRM post graduate students, the first criterion for a respondent that seeks to be included in the sample is that he or she must belong to this population (Mohrman, Gibson & Mohrman 2001, p. 358). As a result, this makes him take note of research gaps that are likely to occur in his questionnaires to understand how they are likely to affect his study. In research, however, their use is more complex Podcast: Play in new window | Download Subscribe: Android | RSS This podcast discusses the data quality concepts of reliability and validity of research tools/instruments.

Internal validity and reliability are at the core of any experimental design. Reliability in research. This allows them to understand the main arguments that justify their studies and specific qualities of phenomena they are studying. He also needs to find out if his sampling techniques stratify the targeted population effectively (Mohrman, Gibson & Mohrman 2001, p. 362). The researcher needs to find out the number of people he intends to gather responses from and how they represent the whole population the survey will be based on. IvyPanda. The research proposal can be envisaged as the process (step by step guidelines) to plan and to give structure to the prospective research with the fina1 aim of increasing the validity of the research. Research validity in surveys relates to the extent at which the survey measures right elements that need to be measured. If everyone shown the proposed test agrees that it seems valid, the face validity of the test has been established. Reliability refers to the ability to consistently produce a given result. What’s your deadline? Since HRM consists of many concepts, questionnaires should be brief and clear to ensure they elicit valid responses from participants. Validity encompasses the entire experimental concept and establishes whether the results obtained meet all of the requirements of the scientific research method. It is important for the data gathered and conclusions reached to correlate to bring about the desired conclusions in a particular study to make its findings more relevant to its users. Therefore, all processes a researcher uses to come up with new bodies of knowledge should measure up to high intellectual standards.

Reliability implies consistency: if you take the ACT five times, you should get roughly the same results every time. Reliability and validity are two terms that the investigator uses interchangeably. It is important for researchers to have safeguards to ensure that methodologies and research designs they use conform to high intellectual standards.

In addition, the researcher needs to note other non- sampling errors in questionnaire design which may affect the quality of responses he obtains. Qualitative data is as important as quantitative data, as it also helps in establishing key research points. Additionally, a researcher may opt to develop his own research methodology which is suitable for his study. Different forms of research design use tests and other procedures to determine the level of validity in a researcher’s work. Examples of a data collection method and data collection instruments used in human services and managerial research will be given. It is important for a researcher to formulate important objectives he seeks to achieve to ensure he comes up with a strong hypothesis.
