Use the image to answer the question.

An illustration shows a number line ranging from 1 to 7 in increments of 1. Different numbers of circles are placed vertically above each number in the number line. The number of circles placed above each number are as follows: 3 circles above 1, 2 circles above 2, 1 circle above 3, 0 circles above 4, 1 circle above 5, 2 circles above 6, and 3 circles above 7.

Answer 1

To determine the shape of the graph based on the number of circles above each number from 1 to 7, we can summarize the data:

- 1: 3 circles
- 2: 2 circles
- 3: 1 circle
- 4: 0 circles
- 5: 1 circle
- 6: 2 circles
- 7: 3 circles

When visualizing this distribution, we see that there are more circles above the lower numbers (1, 2) and then it tapers off equally towards the higher numbers (6, 7).

This creates a bell-like shape that is not symmetrical because there are more counts on one side (the left) compared to the other (the right). Instead, this distribution dips down towards the middle number (4), which can be described as "skewed."

Therefore, the best choice among the options provided is:

**skewed**
