This lawsuit highlights our challenge — we must properly plan for and accommodate variance in remotely collected data, which we argue is a standard and well-known problem for any research data, whether it is collected in the hospital, clinic or at home.
From computation, a sample size of 400 patients would have been sufficient, but we had to take the cluster effect into account, related to the fact that the patients were recruited in different practices (adjustment taking into account the artificial decrease of the variance of measures collected in the same practice).

The process captures the variance in the data collected from trial participants and accounts for any correlations between parameters.
However, we were underwhelmed by the power of tracking approaches to detect more subtle differences in behavior that might explain variance in neural firing collected during our experiments.
Park et al. (2000) analyzed the variance components of endotoxin in dust collected in a one-year longitudinal study of a convenience sample of 20 homes of students, faculty, and university staff in Boston.
By using ordinary smartphones instead of specialized hardware, we believe that a new generation of lifelogging apps can capture the contextual information necessary to interpret variance in the health data collected by wearable devices.
For traditional human societies, mean and variance in offspring numbers were collected from published data sets (Yomut Turks: [26]; Dogon: [27]; !Kung: [28]; Kipsigis: [29]; Ache: [30]).
However, we found that 65% of the total variance in 24-hr urine samples collected 3 days apart was due to within-child between-day variability, even though the 24-hr samples reflect complete sampling with no within-day variability (i.e., the entire sample was collected).
Variance components analysis of samples collected in spring showed different patterns for annual and spatial components of variability.
