Sampling techniques

reliable in the data collection process of an observation study (Bartlett, 2013). The researcher decides how to classify and record the data usually involving a method of sampling (McLeod, 2015. There are a variety of sampling methods for collecting data like event sampling, time sampling and instantaneous (target time) sampling. When the observer decides in advance specified time periods is an example of time

There are multiple types of survey methods utilized in research. Three of the main survey methods include interviews, electronic surveys, and written surveys. In interviews, the assessor works directly with the respondent to obtain responses to the survey. Utilizing interviews allow researchers to obtain comprehensive and thorough responses. Moreover, the interviewer is able to follow-up on certain responses if more information is needed. Despite these benefits, interviews have some potential disadvantages

capital. The specific methods for this research will be qualitative research with snowball sampling (Textbook: Understanding Social concepts). Specifically I propose to use respondent driven sampling to reach hard to identify populations such as those who are most affected from economic inequality and racial segregation. I chose this method to reach members within a specific subgroup in society. This type of sampling connects the researcher to the network of individuals that are specific to this research

When considering if Rind et al. should have been more measured in their conclusions I say no. After reading that article it appeared to me that they covered and analyzed a lot of important material. In the study they compared gender, intensity, and pervasiveness in college students. For anyone who does a study that involves numerous statistical analysis it is hard to accurately measure everyone and everything, especially for something like childhood sexual trauma. Child sexual trauma, or CSA is something

Chapter 2 and 3 offers readers a roadmap for beginning a research project. In chapter 2, the steps of the process of research are discussed. The text first states researchers should decide if problems can, and should be researched, then offers guidance on how to decide. The details about the difference between quantitative and qualitative research and how research problems differ with each method. The chapter provides an in depth discussion on how to to write the “statement of the problem” and provides

Describe the sample. How does this sample represent the population? What makes a sample strong or weak? Evaluate this sample. The sample came from nine hospitals located in 3 provinces in Canada. The sample included 36 medical and surgical units of the nine hospitals (HALL et al., 2010). Workplace interruptions among 360 nurses were examined throughout the day (HALL et al., 2010). A random sample of 113 nurses was selected from the medical and surgical units to participate in a focus group. The

Clinical Overview (Module 2.5) includes Efficacy summary, safety summary, justification of dosing recommendations, appropriateness of product information, future plans for pediatric development, any risk to different peoples, and benefit-risk ratio. For the given product the following objectives need to take into consideration during the benefit-risk analysis. Doses of the Pob (investigational drug) for different age groups, Side effects on the different age groups, Side effects of the pregnant woman

After a detailed appraisal of this article, the strengths outweigh the weaknesses. The experimental design consisted of randomly assigned arms. With the random assignment, results can be generalized to the public. In addition, the study excluded those with comorbidities to reduce the risk of the treatment helping the other disease, instead of the PTSD (Polak et al., 2012). With the group of participants solely having the diagnosis of PTSD, the findings are more accurate for PTSD. Another strength

Random assignment is defined as randomly assigning each subject, therefore allowing them to each have an equal chance. Smith’s experiment was not an example of random assignment because the students were specifically placed in one of his classes to fit their schedule. He had no say on which student would place in which class as it was predetermined by the school. This experiment could have been random assignment if all his students were there at the same time, and he chose the groups by either picking
