The two main probability designs are, probability and nonprobability sampling. Probability sampling know what the exact probability of each selection would be whereas with nonprobability sampling it is unclear. Nonprobability, selecting 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…

At each time point, a T-test statistic is calculated by comparing the mean values before and after this time point. The maximum T-test statistic value and the time is picked up. Then the probability of observing a maximum T-test statistic less than the observed maximum T-test value in a randomly drawn time series is calculated using an approximation function generated from Monte-Carlo experimentation. If the probability is greater than a given criteria (PROB), the time series…

look at those statistics and make a judgment about how they can relate or how they play into that statistic. What intrigues me is who comes up with those statistics? That is why I choose the career statistician to research about. Most people think having a career in statistics would be mind-numbing because you have to use math. This in most cases, math can be unexciting or dull. The reason using math for statistics can be enjoyable is quite interesting. I believe that statistics can relate to…

. Which inferential statistics would you choose for the following sets of variables? Explain your answers (refer to Figure 17.5 on page 384 in Polit & Beck). A. Variable 1 represents the weights of 100 patients; variable 2 is the patients’ resting heart rate. a. The inferential statistics utilized in this analysis is the Wilcoxon signed-rank test, the nonparametric two-group study involves two measurable (paired scores) one being the patients weight and the other resting heart…

Lie with Statistics, was a great read. Each chapter came with a lesson that is very important to learn. Each lesson is good to know so that you won 't get tricked. Now-a-days, people are very gullible and believe anything they hear especially if what they hear is “proven” with statistics. Are these statistics real? After reading chapter 1 of Darrell Huffs shows that we can see the reality of things that way we will not be tricked at all. To do this, he teaches us how to lie with statistics.…

ensure the relevant issues was examined in a comprehensive manner. Statistical tools and methods used where appropriate for analyzing the relationship among the variables and the model. 3.8.1) Descriptive statistics analysis The data that had collected will analyze based on the descriptive statistics analysis. According to You, Chen and Liu (2014), descriptive analysis technique is used to collect actual information in detail and to describe characteristics of certain groups. Descriptive…

purpose, statistics can be the catalyst for decision making in the field of medicine, politics, science, economics, social science and nursing.
