Which of the choices below best describes how to measure the center of this data?

Question

The table shows data from a survey about the number of times families eat at restaurants during a week. The families are either from Rome, Italy or New York, New York:

Rome	21	1	1.5	7.5	6	4.5	6.5	6.6
New York	20	1	3.5	7.5	4	5	6.5	5.2

Which of the choices below best describes how to measure the center of this data? (5 points)

Group of answer choices

a.Both centers are best described with the mean.

b.Both centers are best described with the median.

c.The Rome data center is best described by the mean. The New York data center is best described by the median.

d.The Rome data center is best described by the median. The New York data center is best described by the mean.

Answer 1

6.825 = mean of Rome's data which is greater than all the data except the 21. 21 skews the mean to the right. It's an assymetrical distribution

6.575 = mean of NYC's data, which is greater than 6 of the 8 data points, except 21 and 7.5. It's also skewed but not quite as much

with highly skewed distributions the median is better than the mean. the mean is too skewed by outliers, which, ins some surveys may not even be reliable, or even possible.

median of Rome is 6.55 the average of the 6.5 and 6.6, the middle two numbers, 4th largest and 4th smallest

median of NYC is 5.1 the average of 5 and 5.2, the middle two numbers, 4th largest and 4th smallest

B. both cities' centers are best described by the median
