Price versus precision

Price versus precision: the cost-efficiency performance of trunk posture measurement methods

In a climate of scarce research funds, cost-effective exposure assessment becomes more crucial.  Although direct measurement exposure assessment methods are generally considered the most valuable in terms of accuracy and objectivity, the increased cost of direct measurement means that fewer measurements can be taken.

There is a long-acknowledged tradeoff between precision and cost of exposure assessment methods that is seldom quantified.

The purpose of this study is to compare different sampling strategies for inclinometer-measured, observed, and self-reported trunk posture and determine which is the most cost-effective.  Knowing the price-performance tradeoffs of observational exposure assessment can help researchers make the most of limited funds.
