based on these data, is it better to describe the centers of distribution in terms of the mean or the median? explain.
mean for both coffee shops because the data distribution is symmetric
median for both coffee shops because the data distribution is not symmetric
mean for shop b because the data distribution is symmetric; median for shop a because the data distribution is not symmetric
mean for shop a because the data distribution is symmetric; median for shop b because the data distribution is not symmetric
