Lip strength Normal Values

An estimated normal probability distribution of a group of 171 normal U.S.
persons, aged 18–89, is shown below. Although there were no consistent age
differences there was a pronounced gender difference.
Data are taken from Clark et al., 2012. No significant differences were found
when comparing the right and left lip strengths, so these data have been
pooled. See www.IOPImedical.com for the complete reference of this study,
and details of numerical procedures.
