Enter the total sick and exposed and the total well and exposed into the Calculator. The calculator will evaluate the Experimental Event Rate. 

Experimental Event Rate Formula

EER = a/(a+b)

Variables:

  • EER is the Experimental Event Rate ()
  • a is the total sick and exposed
  • b is the total well and exposed

To calculate the Experimental Event Rate, sum the total sick and exposed with the total well and exposed, then divide the total sick and exposed by the result.

How to Calculate Experimental Event Rate?

The following steps outline how to calculate the Experimental Event Rate.


  1. First, determine the total sick and exposed. 
  2. Next, determine the total well and exposed. 
  3. Next, gather the formula from above = EER = a/(a+b).
  4. Finally, calculate the Experimental Event Rate.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total sick and exposed = 57

total well and exposed = 182

FAQ

What is the significance of calculating the Experimental Event Rate (EER)?

The Experimental Event Rate (EER) is significant as it helps in understanding the proportion of individuals who are exposed to a certain condition or treatment and end up experiencing a specific event, such as developing a disease. This calculation is crucial in medical research and public health for assessing the risk and effectiveness of treatments.

How can the Experimental Event Rate be used in public health?

In public health, the Experimental Event Rate can be used to assess the risk of disease in exposed populations, evaluate the effectiveness of interventions, and guide policy-making and resource allocation. It helps in understanding how different factors influence health outcomes within a community.

Can the Experimental Event Rate formula be applied to non-medical fields?

Yes, the Experimental Event Rate formula can be applied to non-medical fields. For example, it can be used in environmental science to assess the impact of exposure to pollutants, in psychology to evaluate the effect of experimental treatments, and in marketing to measure the response rate to advertising campaigns. The concept of assessing the rate of an event occurring in an exposed group is versatile and can be adapted to various fields.

What are some limitations of using the Experimental Event Rate?

Some limitations of using the Experimental Event Rate include the potential for confounding variables that may not be accounted for, leading to biased results. Additionally, it requires accurate and comprehensive data on both the number of exposed individuals and the occurrence of the event, which may not always be available. Lastly, it does not provide information on the timing of the event, which can be crucial in some analyses.
