Selected Using The Random Sampling Method â€myassignmenthelp.Com

Question: Discuss About The Selected Using The Random Sampling Method? Answer: Introducation The study included participants from South Australia who used bicycles to either go to work or in doing their daily cores. A sample of thirty participants was selected using the random sampling method. This method was selected because it gives every participant a chance to be included in the study and hence reduces bias in any study (Fraley Hudson, 2014). Also, the random sampling method is based on probability hence the researcher is able to choose participants in a simple way by just assigning unique numbers then choosing the participants based on the probability and this process saves a lot of time. The participants chosen were aged between twelve to forty five-years of age and they had been cycling for at least one hour each day hence the sample included participants who were used to cycling but what differed is the number of hours each participant cycled per day. The health back ground of the participants was first examined to meet the requirements for the study. All the participants were not supposed to have any health problems diseases related to obesity. This requirement was necessary because it would help to get healthcare participants hence the results of the study would be very reliable. The data collected was numerical since the study was quantitative. Many scholars encourage the use of numerical data in quantitative studies because its analysis is very simple and it allows comparison hence leading to scientific conclusions which are reliable (Treiman, 2014). Questioners were used as the main tool for data collection. Those questioners were hand delivered to the participants and all the questions included were aimed at collecting scale data. the participants were supposed to record the duration they cycle every day in hours and then their level of Caroline was measured. Also, before the recording of the Caroline levels examinations were done to determine the health background of the participants. After the collection of the data, the researchers went ahead with the process of data cleaning. First, the data was transformed to digital through entering it into Microsoft Excel software where it was saved. After the creation of the excel file, the data was transferred to SPSS software for cleaning and analysis. in this section, the data was cleaned to remove any operations and to see if there are any participants who did not respond to the questioners. This enabled the researchers to estimate the reliability of the data. The process of data analysis was then carried out. Data analysis is the transformation of raw data into reliable information by use of scientific methods and statistical tools. Correlation was used to estimate if there was any relationship between the average number of hours a participant cycled per day and the level of Caroline in the body. SPSS was used to carry out the analysis due to its advanced features which make it easy to carry out the analysis efficiently and in a logical manner. Also, it allows one to compare many variables at once hence making it the best software to use. References Fraley, R. C., Hudson, N. W. (2014).
