In this tutorial, I will show you how to calculate the odds ratio (OR) and 95% confidence intervals (CIs) in Microsoft Excel. Example data To start with, let me introduce you to my example data. Let’s say I performed a case-control study to determine the association between a ...
Population averaged modelscomparemarginal distributionsand give an overview of the effect on a whole population. The margins of a contingency table contain the totals, so it makes sense for them to be used to calculate themarginal odds ratiofor a whole population. On the other hand,subject-specif...
how to calculate p value by hand Explain how frequency is used to inform probability and why this is important. Be sure to include the relevance of p-values as it concerns probability and the relationship with frequency. How do I calculate worry value when only the expected cost is given fo...
In contexts like public health, rare events such as cancer or maternal mortality assume a Poisson distribution, which we can use to calculate confidence intervals used to compare rates. For more, see this handout from the Utah Department of Health and Human Services: This distribution is not sy...

Your hand is 7♦ 5♦. Let’s use our step-by-step process to figure out if you can profitably call based on your pot odds. Step 1: Calculate the final pot size if you were to call. $3 (the size of the raise) + $1 (your big blind) + $0.50 (the small blind) + $2 (...
This, of course, is preferable to actually losing money, so the rule of thumb here is simple: when EV is negative, fold the hand; otherwise, make the call. How to Calculate Pot Odds To calculate pot odds, you simply divide the amount of money you have to put in to make the call ...
