Conclusions:

The density of the test item Dibenzyltoluene was calculated as 1.0441 ± 0.0001 g/cm³ at 20 ± 0.5 °C, which is the mean of two values. Precision of the value is given as maximal error of determination.
The standard deviation of the two values is the same as the maximal error, indicating that correspondence and precision are very good. Therefore, the study is considered valid.

Executive summary:

Using the pycnometer method, a density of 1.0441 ± 0.0001 g/cm³ was measured. This value is the mean of two independent determinations with the error of determination.

Standard deviation was 0.0001 g/cm³, showing very good correlation ot the two determinations.
