In general, the relative risk is calculated by dividing the risk of two different groups. The risk of the group with the particular characteristic is usually presented as the numerator of a fraction. This group is called the exposed group. The relative risk is calculated as the risk of disease in an exposed group divided by the risk of disease ...

Video created: May 8, 2013 Knowing whether or not an intervention works is important when deciding which program or policy to implement. When looking at research evidence, relative risk is a way to determine the relationship between a risk factor and an outcome or the likelihood that an intervention will have an impact on a population. This ...

In this statistics video, I go to the point of the difference between relative risk vs odds ratio, commonly used in biostatistics. I show the different ways that relative risk and odds ratios are calculated and then compare the interpretation of relative risk to the interpretation of the odds ratio.

Relative risk Odds ratio Attributable risk Population attributable risk Population attributable risk percentage

This video demonstrates how to calculate odds ratio and relative risk values using the statistical software program SPSS. SPSS can be used to determine odds ratio and relative risk values for various types of data.

In this tutorial you will calculate attributable risk percent based on the relative risk problem found at http://www.youtube.com/watch?v=V5DCNOwl9IA I get a few comments now and then that attributable risk is ONLY the top part of this equation. I tend to like to call that part of the equation "difference in risk". If it is that difficult to ...

ERRATA: At about the 3:00 mark the slide says "10,00" when it is really supposed to say "10,000." I added a pop up box to fix it. Thanks to Mehdi Hedjazi for pointing this typo out The terms odds and probability are used interchangeably in everyday life. However, in the setting of Biostats they are two different things. Generally speaking they ...

In addition to calculating the risk difference, risk ratio, and odds ratio for a 2x2 contingency table from our previous lecture, we can also conduct various statistical tests depending on the data and our test assumptions. In this lecture we review the chi-squared test, Fisher's exact test, Barnard's exact test, and McNemar's test for paired ...

In fact if you know the Odds ratio for one cell, you can find the odds ratio for all cells. Odds ratio for female/male who died = 0.088. This is also the odds ratio for Male/Female who survived. If you inverse 0.088, it will give you 11.36, which is the odds ratio of male/female who died. This is also the odds ratio for female/male who survived.

This event is designed to provide an entry-level introduction into probabilistic analysis and will show how simple it is to add Monte Carlo simulation and other techniques into your cost estimating and risk register models.

The relative risk (RR), also known as the risk ratio, is a statistical measure used in epidemiology and medical research to quantify the strength of the association between an exposure (such as a risk factor or treatment) and an outcome (such as a disease or health condition). It compares the risk of an event occurring in one group (exposed to ...
