Question

Compare the data sets given below and identify the correct statements.




Statement I: Data A is symmetric. Hence, it is easier to find the center of the data.
Statement II: Data B is skewed. Hence, it is easier to find the center of the data.
Statement III: Data A is skewed.
Statement IV: Data B is right-skewed

• A. Statements I and II are correct.
• B. Statements I and IV are correct.
• C. Statements IV and II are correct.
• D. Statements II and IV are correct.

Answer 1

The correct option is B Statements I and IV are correct.


Data A is symmetric.
We also know that it is easier to find the center of the data when the distribution is symmetric than when it is skewed.
Hence, statement I is true.
And if statement I is true, then statement II and statement III are false.


Data B is right-skewed because most of the data is on the left, and the tail of the line plot extends to the right.
Hence, statement IV is true
