Study Design and Questionnaire construction A cross-sectional anonymous survey was carried out among medical students, residents and attending physicians from two medical faculties in France (Faculty of Medicine of Nancy, University of Lorraine; Faculty of Medicine of Poitiers, University of Poitiers). The instrument “Nancy-Poitiers Translational Research Study” was developed in the Faculty of Medicine of Nancy after an extensive literature review. Content validity of the questionnaire was…

To better understand the scientific question in our case study, we had to first identify the variables of interest, the population, the sample, the parameters and statistics of the dataset. The variable of interest for this study is tip amounts, as that is what the owner of Sofrittos is analyzing. The population of the data set is tips received by Sofrittos waiters and waitresses, while the sample is the 80 tables of diners collected from the Bureau of Labor Statistics. The parameter of the…

which is how and can you actually gather the data, the instrument development, which is to put the data into context, and the third process which is going to be discussed in this chapter is the sampling process, which is a representative population on a broader scale. The third process known as the sampling process can also be call a research design. This step of the process involves comparison and seeing if there is a strong correlation between the data that is collected. To start off, there…

Data Collection The purpose of this data collection is to answer the principle research question, “Are UAS a practical alternative to monitor air quality and levels of pollution?” and use that data to accept or reject the hypotheses. In planning for data collection, P. Leedy, & J. Ormrod, authors of Practical research: Planning and design (2016) have established five essential questions that need to be answered: 1. What data will be collected? 2. Where are the data located? 3. How will the…

Chapter 1: Using key words from Chapter discuss whether the article is valid or credible. Why or why not? The article is both valid and credible as the author uses historical statistical information to identify prevalence within the target population, although it is not stated where the statistical information was derived from. Although this information is vulnerable to falsifiability it does not appear that this has occurred. The validity of the information provided in the article is further…

theory, and applied research, aimed to increase comprehension of naturally occurring events and add to the solution of social problems, are closely tied in social psychology (Kassin, Fein, & Markus, 2013). A common style of research is a survey. Two examples of surveys that one can participate with online are Male Body Image and Muscularity and Masculinity, Identity, and Mental Health. Male Body Image and Muscularity Conducted by Teodora Pavlovic, Lisa Mask, Ph.D., and Fushia…

Covert observation is when the participant is unaware that they are been observed. Often, some individuals go under cover to do their observations. (Encyclopedia.com, 2015) The advantages of covert observation is it does not disturb the normal behaviour of the group because the participant is unaware they are being observed so they would not act differently they would act in a way they would normally act. Therefore, there is higher validity because the participant would not be able to change…

Exercise 1: Sampling This group of vehicles I chose to sample was selected on September 21st, 2016.

in case of SEG. And overall aggregation of various sampling methods in different forest types of NAI yielded about 446 species. The reason that could be attributed to high species richness in SEG is mainly due to its distribution at heterogeneous topographic conditions. Sampling strategy played major role in accounting varied species richness. In all the forest types contiguous plots recorded low number of species to their counter random sampling. Contiguous plots show the homogeneous…
