Is it necessary to use more than one analytical methods when comparing 2 variables? i.e is it necessary to include another statistical method if using chi square test or is only chi square test enough just to compare variables and find the dominant group.

What is the most appropriate statistical analysis method that can be used for a cross sectional study.

In probabilistic sensitivity analysis, rather than assigning a single value to each parameter, computer software (such as Crystal Ball, TreeAge, WinBUGS or other software) is used to assign a distribution to all parameters in the model. The ranges are determined by: The average value, The standard d...

Probabilistic analysis is based on Monte Carlo simulations. Examines the impact on the results of the analysis when variables are varied simultaneously according to predefined distributions. Advantages:Permits varying all parameters in the model simultaneously and enables calculation of the expected...

Sensitivity analysis is the process by which the robustness of a cost-utility analysis (CUA) is assessed by examining the changes in the results of the analysis when key variables are varied. Sensitivity analysis should include univariate (simple) analysis and multivariate analysis. When undertaking...

Antibiotics are not needed to treat most sore throats, which usually improve on their own within 1–2 weeks. Antibiotics will not help if a sore throat is caused by a virus or irritation from the air.

2 b ) If you have a viral infection, you will be contagious until your fever runs its course. If you have strep throat, you may be contagious from the onset until you've spent 24 hours on antibiotics. The common cold usually lasts less than 10 days. Symptoms, including fever, may peak around three t...

2. Some factors increase the risk of developing sore throat: - Age: children are very susceptible to viral infections ENT, especially if it is in contact with many other children (school, nursery) - People come into contact with too much air, improperly adjusted or poorly maintained (which become “n...

Causes of sore throats range from infections to injuries. Here are eight of the most common sore throat causes. 1. Colds, the flu, and other viral infections Viruses cause about 90 percent of sore throats (2). Among the viruses that cause sore throats are: the common cold influenza — the flu mononuc...
