RET3050 Lesson 09 – Discussion 09- 150 words minimum answering all 5 questionsThe use of descriptive statistics and particularly frequency distributions are essential to providing an efficient method to summarize and illustrate data relationships. The utilization of frequency distributions that displayed the evolving incidence curves of COVID-19 for local and national comparisons over time captured the world-wide audience for months.
The object of this discussion is to contrast the important frequency distributions utilized for informing the public as well as researchers, the COVID-19 incidence over time and the distribution’s shape.

It is both important to assess the data being collected (incidence of infection with CV-19) and the analysis of a trending revealed by the distribution. Review the assigned video and world data site for comparative distributions.
State your opinion for the data type (as classified in the video and Table 11.1 of your text) being measured.
Why is it important to classify the level of measurement in data analysis?
Comment, as well, on the importance of the shape of the distribution when comparing the evolving distribution over time or between different countries.
How does the skewness and kurtosis of these curves impact the decisions made about the impact of the COVID-19 infection rate

The use of descriptive statistics, particularly frequency distributions, that are compared for groups in health care research, are essential to providing a comprehensive analysis of outcomes in health care research. The Kaplan Meier Survival Analysis is a particularly useful comparative device for evaluating the “so what” outcome feature of medical research– comparison morbidity of the patient groups (survivability) when comparing treatments in healthcare research for multiple groups.
After reviewing the two assigned Lesson 10 videos Contrast how the Kaplan Meier comparison and the use of probability analysis is linked in a research study, in general.

Read the Abstract of this Study on Management of Patients during Mechanical Ventilation.
What is the Target Outcome Measure for the Study (Table 1)?
How does the Kaplan Meier Plot in Figure 2 serve as an inference to future professional practice.
What probability level is cited for this comparative relationship of survivability with and without the use of a Neuromuscular Blocker? What do the researchers say regarding the use of the studied treatment variable cistracurium?
Comment on the support for the researchers’ failure to reject the null Hypothesis (Ho) for this study. Does the p value selected provide an acceptable confidence interval?
