Please post a scholarly reply that are about 150 words each. There are 3 different posts below. Read and come up with about 150 words, scholarly written to each of them. It is NOT required that every question or point be analyzed; more focused discussions on one or more central points are encouraged. Original questions and posts: Post 1 Q1: Review and discuss how to develop interview questions. When developing interview questions, the researcher must keep in mind the construct they are attempting to describe without being biased (McGregor, 2018). A best practice is to employ open-ended questions, what McGregor refers to as “an interview guide,” and meaningful prompts to keep the interview on track and address any lulls within the flow of conversation (p. 244). McGregor (2018) also recommends sending follow-up questions to participants to address any issues that arose “during the data collection process” (p.244). The type of questions is also dependent upon the format of the interview. Informal conversation interviews require less structure and may invoke more spontaneous responses (McGregor, 2018). Q2: How do interview questions differ from research questions? Research questions focus on the research itself and set the stage for how researchers will collect data from participants (McGregor, 2018). Interview questions are those presented to participants in an attempt to answer a research question, describe a phenomenon, or explore a relationship. According to Creswell (2005), “Research questions in qualitative research help narrow the purpose of the study into specific questions” (p. 136). Q3: Discuss validity and reliability in quantitative research. Validity in research relates to how trustworthy the information is as presented by the researcher (McGregor, 2018). It is crucial to be critical of research in order to expose its flaws so that the forward progression of information can take place and future research can utilize the information with confidence. According to McGregor (2018), there are four main types of validity to take into consideration: internal validity, external validity, logical validity, and internal consistency. Each one carries a portion of the whole truthfulness of the study and should be considered by the researcher at every step in the process. Reliability relates to the ability of others to replicate the research given the same design and produce similar results (McGregor, 2018). The method must be reproducible and appropriate information must be provided so that others can successfully carry out the research (McGregor, 2018). Q4: Describe how you will measure all of your variables in your proposal, including survey names and references, as well as how you know they are valid and reliable measures. I plan to use the Teas (1981) survey instrument, which will be based on a modified Sims et al., (1976) scale to identify phenomena within the domestic palliative care industry. The survey instrument used to collect qualitative data has been validated in previous studies, and the adaptation will not alter the effects of the instrument, only addressing a specific population.
