The box plot above represents data which is:
- A.
Perfectly Symmetrical
- B.
Approximately Symmetrical
- C.
Positively Skewed
- D.
Negatively Skewed
- E.
With Outlier(s)
- F.
Approximately Symmetrical, but Bi-modal
Correct Answer
C. Positively SkewedExplanation
The box plot above represents data that is positively skewed. This means that the tail of the distribution extends towards the higher values, indicating that there are more data points on the lower end of the scale. The median is closer to the lower quartile, and the upper quartile is further away from the median. This suggests that there are a few extreme values in the data set that are driving the skewness.Rate this question:

Negatively Skewed
- E.
With Potential Outlier(s)
- F.
Approximately Symmetrical, but Bi-modal
Correct Answer
B. Approximately SymmetricalExplanation
The box plot above represents data that is approximately symmetrical. This can be inferred from the fact that the median line in the box plot is close to the center of the box, and the whiskers on both sides are of similar length. Additionally, the box itself appears to be symmetrical. While there may be some slight deviations from perfect symmetry, the overall shape of the box plot suggests that the data is approximately symmetrical.Rate this question:

The bar chart above represents ordinal data which is:
- A.
Perfectly Symmetrical
- B.
Approximately Symmetrical
- C.
Positively Skewed
- D.
Negatively Skewed
- E.
With Potential Outlier(s)
- F.
Approximately Symmetrical, but Bi-modal
Correct Answer
B. Approximately SymmetricalExplanation
The bar chart represents ordinal data that is approximately symmetrical. This means that the distribution of the data is balanced and does not have a significant skew towards one side. The frequencies or values in the chart are evenly distributed on both sides of the chart, indicating a symmetrical pattern. However, it is not perfectly symmetrical as there may be slight variations or imbalances in the data.Rate this question:
