. so, the
is a more appropriate measure of
number of trading cards sold
number of customers

Explanation:

Step1: Analyze the histogram's symmetry

A symmetric distribution has data evenly distributed around a center, with left and right mirroring. Here, the bars (1 - 3: ~7, 4 - 6: ~5, 7 - 9: ~8, 10 - 12: ~3, 13 - 15: ~1, 16 - 18: ~1) don't mirror. The left and right sides (low and high ranges) have different frequencies, so it's not symmetric.

Step2: Determine appropriate measure

For non - symmetric (skewed) distributions, the median is more appropriate as it's resistant to skewness, unlike the mean which is affected by extreme values. For symmetric distributions, mean is often used, but here since it's not symmetric, median is better.

Answer:

The distribution of the numbers of trading cards sold is best described as not symmetric. So, the median is a more appropriate measure of center.
