Stratified sampling

and Post traumatic Stress: Early Life Versus Adulthood Traumas (Ogle & Rubin, 2015), probability sampling was used, with a population pool drawn from the “13th Wave” of the University of North Carolina Alumni (1964 - 1966) Heart Study, an ongoing longitudinal study of University of North Carolina students and their spouses (Sieger et al, 1992) including a total of 1598 participants. A convenience sampling of USC alumni would complete a Traumatic Life Events Questionnaire, PTSD Checklist, NEO…

population that was being targeted in this study was the 3 years old. The preschoolers were the group of people they wanted to learn about. (Dyer, 2017) Simple random sampling would have been the best to use because every member within the population would have an equal chance of being selected. (Dyer, 2017) Simple random sampling would of been the best because it can be a small enough group to be able to obtain the desirable results. 3. What is one ethical issue that the researchers probably…

According to Bachman & Schutt (2014): Research should expose participants to no more than minimal risk of personal harm, researchers should fully disclose the purposes of their research, participation in research should be voluntary, and therefore subjects must give their informed consent to participate in the research, and confidentiality must be maintained for individual research participants unless it is voluntarily and explicitly waived. (p. 60) Although Dr. Coswalt protects the research…

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…

All companies have their tricks to make you buy their product. Some companies like to draw you in with advertisements and the promise of their product to be good for you. Companies like General Mills and Kellogg’s use another trick that fools every day people into buying their products. What General Mills and Kellogg’s do is on the food labels of their product, they put different forms of measuring ingredients that might not be as good for you than it should be. The two biggest measurements used…

physically punished their children (Straus, 1983; Straus, Gelles & Steinmetz, 1980; Wauchope & Straus, 1990). Sampling of college students indicated similar data with a 90% over, reporting some form of corporal punishment was imposed (Bryan & Freed, 1982; Graziano & Namaste, 1990). Sampling The sampling method that will be used for this research is clustered, stratified and random sampling of single parents, married couples…

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…

variables. It will also include dichotomous questions. Sampling: My target population and the sampling frame are children ages twelve to eighteen, in grades sixth through twelfth grade, which are in disadvantaged environments, according to the United States Census. Probability sampling will be used so that it can be known in advance how likely it is that certain element of the population will be selected for the sample. Along with that, stratified random…

I am writing them email to inform you why we as a group, chose the secondary sources of data listed in the plans and why we determined using the sampling technique in the way we did rather than using the other methods.

obtain, as participants may easily be accessible and available (Frankfort-Nachmias & Nachmias, 2008). However, it may skew the sample, tainting it through introducing sampling bias. As a result, this strategy may not culminate in a representative sample of the population (Frankfort-Nachmias & Nachmias, 2008). Likewise, purposive sampling has the drawback of being based on the subjective judgment of a researcher to obtain a sample (Frankfort-Nachmias & Nachmias, 2008). Since it is impossible to…
