Alternatives: "representative sample" or "valid sample".
Finally, in selecting sampling locations, certain site characteristics potentially impeding accurate sample collection should be considered (e.g., construction, lack of secure outdoor space or power outlets), and incorporated into previous methods for optimizing concentration variability, such as that outlined in [ 12].

In a statistical sense, we would call this bias: that the polls are not taking an accurate sample of the voter population.
Reliability-based geotechnical design entails accurate sample statistics (i.e., mean and standard deviation or coefficient of variation, denoted herein as cov) of soil parameters.
Therefore, accurate sample-profile estimations can be obtained even at frequencies near and beyond the closed-loop control bandwidths.
This paper presents an efficient and accurate sample-based approach to determine probabilistic minimum and maximum extremes of the fundamental frequencies and the angular positions of their occurrence.
Instead, we rely on the microcontroller clock to get an accurate sampling rate.
While the professional pollster's "accurate sampling" is not the goal here, Mr. Celender's mailing list could use some cross-generational freshening.
