**4.2. Data review**

When assessing IAQ in relation to the specified Ta, RH and CO2 criteria, the maximum and minimum values recorded are of most significance as well as the subsequent range pro‐ duced. A graphical output, visually representing the continuous change in these values over time is appropriate for analysis and discussion. Mean values calculated from these indica‐ tors can sometimes be of use to give an overall representation of the data. However, this sta‐ tistic can overlook significant individual moments, diluting the importance of some data, and thus failing to give an accurate depiction of performance. Mean values may be more ap‐ propriate for other IAQ indicators, such as VOCs and plasticisers, which have constant background levels. The data collected was subject to certain variables and limitations.
