What are data informatics algorithm?

is there a role for the protein data bank in biochemical research? if so, describe it.    I am so confused on what he is asking our textbook doesn't talk about that. we are using the principle of biochemistry eighth edition: David L.Nelson

Suppose a researcher is investigating the measurement ability of a new device intended to read the freezing point of a chemical compound. The substance used in the investigation has a known freezing point of -24 degrees Celsius. The researcher conducted a series of 10 sample measurements of the freezing point, and the results are represented below. What can we say about the device with regards to its precision, and potential bias?   Measurement Freezing Point (degrees Celsius) 1 -26 2 -18 3 -32 4 -31 5 -24 6 -24 7 -24 8 -24 9 -11 10 -37

please help me, I am using this to study but I do not know if my answer is correct.
