# Relative Risk Calculator

## About Relative Risk Calculator (Formula)

The Relative Risk Calculator is a tool used to quantify the likelihood of an event occurring in one group compared to another. Relative risk is a measure of the strength of association between a risk factor and an outcome. The formula for calculating relative risk is as follows:

Relative Risk = (Risk in Group A) / (Risk in Group B)

Where:

• Relative Risk: The measure of the association between the risk factor and the outcome.
• Risk in Group A: The probability of the event occurring in Group A.
• Risk in Group B: The probability of the event occurring in Group B.

Relative risk values greater than 1 indicate an increased likelihood of the event occurring in Group A compared to Group B. Values less than 1 suggest a decreased likelihood, and a relative risk of 1 indicates no difference in risk between the two groups.

The Relative Risk Calculator is frequently used in medical research, epidemiology, and public health studies to analyze the impact of risk factors on health outcomes. It allows researchers to assess the strength of association between exposures and outcomes and make informed decisions about interventions or preventative measures.

Using the Relative Risk Calculator helps researchers and health professionals quantify the impact of risk factors, aiding in evidence-based decision-making and promoting a deeper understanding of the relationship between variables.
