The patterns of questioning used may either describe or gradually predict the manner in which different participants involved in the study are likely to respond. More importantly, both academic and real world applications of knowledge obtained should be able to verify the accuracy and suitability of various research processes used. Research validity in surveys relates to the extent at which the survey measures right elements that need to be measured. External validity is the process of examining the results and questioning whether there are any other possible causal relationships. However, a researcher needs to understand differences between academic environments and real world business environments and how they impact on his work. An effective research process needs to focus on situational factors that impact on the information gathered from respondents. Therefore, using literature already gathered, a researcher is able to make inferences on the type of results he is likely to obtain to understand if they confirm or contradict his earlier assumptions. Content Validity 1. The stratification technique will make it possible for the researcher to find out if the sample he has chosen is a true representation of all postgraduate HRM students in the institution.
