Question

Identify the data which is neither symmetric nor skewed.

• A. Only Data 4
• B. Only Data 1
• C. Data 3 and Data 4
• D. Data 1 and Data 2

Answer 1

The correct option is A Only Data 4

Let’s check the given bar graphs to find the data which is neither symmetric nor skewed.

Data 1

The left side of the graph is a mirror image of the right side of the graph. Hence, Data 1 is symmetrical.

Most of the data is on the left side of the graph, and the long skinny tail extends to the right. So, Data 2 is right-skewed.

Data 3

Most of the data is on the right side of the graph, and the long skinny tail extends to the left. So, Data 3 is left-skewed.
Most of the data is neither on the left side nor on the right side of the graph. Also, Graph 4 is not symmetrical. So, Data 4 is neither symmetric nor skewed. Hence, option D is the correct answer.
