Stratified sampling

1. In “The Early Catastrophe”, Hart & Risley provided a figure that demonstrates the vocabulary size trajectory of the children in the study, stratified by age group (page 4). It appears that the trajectory of vocabulary size between children of middle/lower SES versus those on welfare remains very similar until about 23 months of age. This made me wonder why it is that the vocabulary size trajectory seems to dramatically increase around this age among children of lower/middle SES families, in…

Corps Armed Forces of the Philippines, Philippine Military Academy, Fort del Pilar, Baguio City. The researchers will use the stratified random sampling in order to determine the number of respondents since the population totaled to 875 cadets. This method will yield the manageable sample that will be studied and be taken respondents. The researchers will use this sampling technique because the participants are randomly selected from the different classes in the CCAFP. The researchers will be…

hospital in the NWP. The population for this study determined as different views was obtained regarding the job satisfaction. Probability-stratified random sampling was used in order all categories of nurses had an equal chance of being included in the study. The respondents satisfied as per their level training, namely PNs,ENs,ENAs, (Nursing Act 2005:5). The sampling frame was obtained from the monthly allocation in order to get the total number of nurses working at the hospital. All strata…

However, abilities for operating results of laboratory and imaging tests, prescribing drugs, tracking immunizations are less available (Gans, 2005). There have been a number of stratified random sampling studies across hospitals and medical centers to see how the originators of EHR adoption evolve and to allow for testing the predicting legality of the theoretical foundation (Gagnon, 2010). In every study done, there have been similar findings…

This type of sampling works best when trying to look at one particular issue, and then attempting to compare two or more groups. This technique offers a higher change of the study being statistically correct. This method requires dividing the population into groups, and then randomly selecting the final subjects from the different social stratification (Survey Sampling Methods, 2016). This study would have to be conducted with children ages…

Researchers used convenience sampling to find participants for the study by placing fliers in 16 mental health clinics in the Netherlands and allowing interested parties to apply for inclusion. A list of criteria was also used to narrowly focus the study to a particular population. The sample size admitted into the study was 159 adolescents between the ages of 12-17. To increase the validity of the sample, adolescents were randomly placed into two groups and then stratified into smaller groups…

in which within Latino group differences were discussed, addressed one or more of the preliminary research questions, and added to the foundation surrounding this topic. The observed research designs that were most often used were longitudinal, stratified, and cross-sectional. The most observed research methods were semi-structured interviews, focus groups, and surveys. There were no uniform research design or methods used throughout the literature, however for the majority of research findings…

This article presents a recent study regarding the impact antibiotics have on children’s risk of weight gain. In this study, the findings were based on more than 60,000 prescription records of children who had visited pediatricians twice or more in their first two years of life, and then the researchers analyzed the records again when the children were two years of age. The researchers looked at the association between how many times the children received antibiotics and its relevance to their…
