Utilizing the information from the table above the mean, median and standard deviation will be calculated. The mean equals the average of the sample by adding all the values of the samples and then dividing by the total number of items. The mean for the samples collected is 14.87 ounces which rounded up 14.9 ounces. The median is calculated to be 14.8 ounces. The median is calculated by averaging the data in order and finding the midway point of the data set. Last to find is to find the…

for each domain will be selected according to the distribution of the threshold values across the latent scale and the discrimination value; item that has threshold values cross the whole latent scale and high discrimination value will be selected. Sample Size Graded response IRT model requires 250 subjects to be estimated. However, approximately 500 subjects are recommended to get more accurate estimation of the model parameters [56]. We have more than 500 subject in the database that we are…

At a very young age I knew that helping other people was what I was destined to do.

Another large gap in the research is the lack of racial diversity in the samples of the studies. Every study predominantly featured Caucasian participants; other racial groups were limited in their representation. One factor to consider is that Caucasians on average…

The performance plan involved looking at the overall performance model in different sections: calls per hour, random sample method, and performance improvement. The call model showed that the calls per hour could be changed from a per hour model to a per month model. This allowed agents that were struggling with hitting the per hour goal, to have the entire day to…

each sample unit is not known, leaving the selection up to the researcher. In the case of Santé Fe Grill they should rely on probability sampling because each unit is identified. Under probability sampling, there is stratified random sampling. Stratified random sampling involves taking the population and diving them up into even smaller groups, known as strata. These groups will be divide with some they have in common, whether it be income or location. From there they would take random samples…
