A drug company is evaluating a new method to measure levels of sugar in blood samples. The test is run hundreds of times on samples where the true level of sugar is already known. No test will be perfectly accurate all of the time, but it is important that the result of any test be as close to the correct value as possible.
Which of these statistical measures will be most helpful in determining if the testing method in the attached description meets this condition?
1. the mode of the test results
2. the mean of the test results
3. the minimum and maximum values of the test results
4. the standard deviation of the test results
