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
