Statistical Power
Term:
Statistical Power
Definition:
The probability that a study will detect a treatment effect if one exists.
What is Statistical Power?
Statistical power is the probability that a clinical trial will detect a true effect or difference between treatments when one actually exists. It measures the ability of a study to avoid a false negative result, where a real effect is missed (also known as a Type II error). Power is influenced by factors such as sample size, effect size, variability in the data, and significance level.
For example, a clinical trial with 80% statistical power has an 80% chance of correctly identifying a treatment effect if it exists, leaving a 20% chance of failing to detect the effect.
Why is Statistical Power Important?
Statistical power is critical for designing reliable and meaningful clinical trials. Adequate power ensures that the study has enough participants and is properly structured to detect meaningful differences between treatments.
Underpowered studies risk producing inconclusive or misleading results, while overly powered studies may waste resources or expose unnecessary participants to risk. By optimizing statistical power, researchers maximize the efficiency and impact of their trials.
How Statistical Power Relates to Your Clinical Trial Experience
At Anchor Medical Research LLC, statistical power is carefully calculated during the trial design phase to ensure the study has the right balance of participants and resources. This helps minimize the burden on participants while ensuring the trial can generate reliable and actionable results.
As a participant, you are contributing to a trial that has been thoughtfully designed to maximize its potential impact while respecting your time and effort.
What This Means for You
When you join a clinical trial, the statistical power ensures that your participation contributes to a study capable of producing meaningful results. Your involvement helps researchers determine the safety and efficacy of treatments with confidence and precision.
At Anchor Medical Research LLC, we value your contributions and ensure that our trials are designed to make the most of every participant’s involvement.
