Paper Sample on Obesity Prevalence Among US Children: A Study of California

The data that will be collected will be quantitative in nature, and it will relate to the obesity prevalence among children in the United States. The scope is wide, and it will be narrowed down to the state of California, and the details obtained will be a representation of the entire country. The community in this state will be enough for it will cover children from all backgrounds. The levels of measurements that will be used in this case will be the interval that will help in raising the differences that exist between values and the order. Therefore, it will be possible to determine the central tendency of the data collected through the measurement of the mean, mode, and standard deviation figures.

The assumptions that will be made regarding the existing data include that the details obtained in California will be a representation of the entire country. It will be assumed that the sample data calculated is adequate and all the children involved in this obesity study are affected by the consumption of junk food, lack of exercise, and the lack of a better clinical treatment process.

The factors that should be considered when selecting an instrument for a study include the program objectives alignment. The tool selected should align with the learning objectives of that particular research, for this will help to raise the effectiveness of the process leading to the results obtained having a high level of accuracy and more information (Buta et al., 2016). It is critical to assess the resources that will be needed when working with a given instrument, considering that some of them will require to be purchased and funds may not be adequate. Additionally, some may require time and energy and these resources may not be available, leading to the study process getting derailed. Another issue to consider when selecting a research instrument is the quality of a tool. High-quality tools will lead to the realization of trustworthy scores. It is essential to understand the topic frameworks and concepts.

The measures that a researcher can use in the process of selecting the study instrument include searching for them over the World Wide Web (www) and the internet. The published articles can help a researcher in the determination of the right instruments to use in their study process. The research conferences contain details on the instruments that have been used in other studies before the publication of research findings (Chiarotto et al., 2016). It is also possible to contact researchers that have done successful studies on the same topic to seek information about the instruments they used.

In the process of searching an instrument that will be involved in the study, it is critical to note that previous studies on the same topic done by other researchers are included. Therefore, the systematic review will be an essential procedure that will help in realizing the combination of multiple previous studies. The utilization of the data that is already in existence will be a critical way to manage, the study especially when the resources are inadequate (Taber, 2018). Additionally, the procedure will make it easier to have findings that can be published in a short period.

Maintaining a log of activities or the diet that the study participants are taking is essential, for it will help to determine if there is a correlation between the consumption of foods with high-fat content and obesity. The study will be done before the experimental manipulation is undertaken, and after it has been initiated. The move will make it possible to note any changes. For example, to determine if the physical activities are affecting the management of obesity, it is useful that the weight if the study participants are taken before commencing the study. The participants should engage in physical exercises for a given duration and then their weights taken. If there is a notable difference, it will be possible to understand if the physical exercising process is affecting the childhood obesity in the region of California and the United States in general.
