Cumulative probability of ovulation as a function of duration of the pre-ovulatory period. Panel A presents the data (dark red points) and fitted shifted exponential distribution (red curve) for the 34 pre-ovulatory period durations observed for the Playback group, while panel B displays the data (17 pre-ovulatory period durations; dark blue points) and fitted model (blue curve) for the Controls. The matching-color shaded regions and dashed curves delimit the 95% confidence intervals associated with each model fit. Horizontal dashed lines show the \({T}_{80}\) synchrony metric, which is the shortest possible interval that contains 80% of the ovulation events. Note that the x- and y-axis ranges are held constant across panels.
