Auditory brain stem response laboratory norms: when is the data base sufficient?

D A Sklare

    Ear and Hearing

    Summary

    The standard error of the mean can determine if enough subjects are sampled for auditory brain stem response norms. If the standard error is within the lab

    Area of Science:

    • Audiology
    • Biostatistics
    • Neuroscience

    Background:

    • Establishing reliable laboratory norms for Auditory Brain Stem Response (ABR) testing is crucial for accurate diagnosis.
    • Current methods for determining adequate sample size may be inefficient.

    Purpose of the Study:

    • To propose a statistical method for assessing sample adequacy in ABR norming studies.
    • To introduce the standard error of the mean as a key metric for sample size validation.

    Main Methods:

    • Utilizing the standard error of the mean (SEM) as a statistical index.
    • Calculating SEM post-hoc to evaluate collected data sets.

    Main Results:

    • A calculated SEM within the laboratory's measurement resolution indicates a sufficient sample size.
    • This approach provides a reliable estimate of the true population mean.

    Conclusions:

    • The standard error of the mean offers an objective criterion for determining sample adequacy in ABR norming.
    • Employing SEM can streamline the data collection process by avoiding unnecessary subject recruitment.
