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...
