Question

Begin by examining the histogram’s overall shape and the positions of the mean and median lines.
Option A: 'In this histogram, the data is positively skewed data.' A positively skewed (right-skewed) distribution would have a longer tail on the right side (toward higher values) and the mean typically lies to the right of the median. Here, the data and tail appear toward more negative values, not toward higher values, so this is unlikely.
Option B: 'In this histogram, the data is negatively skewed data.' The plotted data cluster toward higher (less negative) y-values with a tail extending toward more negative values. If the tail is on the left, a characteristic feature is that the mean tends to be pulled to the left of the median, so the mean line should lie left of the median line. The orange lines show the mean and median positions, and their relative placement supports a leftward tail.
Option C: 'In this histogram, the data is both negatively and positively skewed.' A distribution cannot be simultaneously skewed in two directions in a single continuous sense; skewness is described as a single direction (left/right). The histogram shape and the mean/median arrangement do not indicate a bidirectional skew as a distinct property.
Option D: 'None of the above options.' Since the histogram clearly suggests a left (negative) tail and the mean/median placement aligns with a negatively skewed distribution, this option would be incorrect.
In summary, the visual evidence—the concentration of data toward higher values with a longer tail to the left, coupled with the typical mean–median positioning for a negatively skewed distribution—points to the negative skew interpretation being the true one. The other statements either mischaracterize the tail direction or rely on an invalid notion of dual skewness. Finally, the phrasing and axis orientation in this figure confirm the leftward skew pattern rather than a rightward one, supporting the characterization as negatively skewed.
