Describe the scales of measurement of data that should be summarized by a measure of location such as a sample mean and a sample median? When is the sample median a better measure of location than the sample mean? Why do we use the sample mean as the measure of location most of the time in practice and in statistical inference?

OD. Shape of the distribution Explain why the mean should not be found fora sample of zip codes. Which measure of center should be used instead? Choose the correct answer below. O A. Zip codes are quantitative data, but are at the ordinal level of measurement. Since they cannot be added in a meaningful way, the mean cannot be found. The mode should be used instead. O B. Even though they are numeric data, zip codes are qualitative since they...

The "best" result is always associated with the measurement with the smallest uncertainty. Measurement B has half the standard uncertainty of measurement A. Therefor e our 68 % coverage probability is associated with a smaller interval (83.44 g o 83.56 g) for measurement B than measurement A (83.38 g to 83.62 g). In other words we have better knowledge about the value of the measurand from measurement B, since we have the same coveroge probability associated with a norrower interval....
