Strata were defined by industry (TMD or Biotechnology) and<br />

organisational size, which was based on employee numbers<br />

(small, medium, and large). Strata were defined for both<br />

responders and non-responders, where possible. Within each<br />

stratum the arithmetic mean in most cases provided a reasonable<br />

measure of the central tendency.<br />

Data from the 2011 survey was compared to the 2009 survey.<br />

Where respondents had participated in both surveys, the median<br />

secular trend (measured as the ratio of the 2011 value to 2009<br />

value) was assessed for each measures of interest. Several<br />

organisations had responded to the 2009 survey but not the 2011<br />

survey. In estimating the total population, it was reasoned that the<br />

2009 data was likely to better inform our estimates of 2011 than<br />

using the mean from other respondents. The secular trend value<br />

was applied to those organisations’ values in 2009 to derive<br />

2011 estimates.<br />

The total population estimates were derived from bootstrapped<br />

estimates of the mean with each stratum. The variance of the final<br />

estimate was derived from the variance of the bootstrapped mean<br />

in each stratum. Where relevant, the data are presented with 95%<br />

confidence intervals.<br />

Given the population estimates are not necessarily derived from<br />

a representative sample they should be considered speculative<br />

and taken only as a guide to the state of the industry, relative to<br />

the reported figures from previous comparable surveys. In the<br />

QLS <strong>Industry</strong> survey 2009 and the 2007 <strong>Queensland</strong> Biotechnology<br />

<strong>Industry</strong> and <strong>Queensland</strong> TMD <strong>Industry</strong> surveys, a similar<br />

estimation method was employed. Where possible the approach<br />

used to calculate population totals are consistent with those used<br />

in previous surveys. In some cases, 2007 survey results were<br />

reanalysed using the methodology applied to the 2009 and 2011<br />

survey results.<br />

There are variations between the 2011, 2009 and 2007 surveys in<br />

terms of the specific organisations that responded to the survey<br />

in each year. Thus, the sample population is different for each<br />

survey. In addition, income data for the TMD analysis in 2007 was<br />

collected as an income range and not a specific figure as was the<br />

case in subsequent surveys. Direct comparisons between figures<br />

from different surveys may indicate change but any such changes<br />

cannot be taken as definitive.<br />
