Question

the line plot below shows the number of pets owned by 25 people who were randomly surveyed in a particular town. describe the shape of the distribution.
options:
bell - shaped, bimodal, no outlier
bell - shaped, unimodal, no outlier
skewed right, unimodal, outlier at 0
skewed right, bimodal, outlier at 0

Explanation:

Step1: Analyze modality

Check the number of peaks (modes). The plot has one main peak (around 4 - 5), so unimodal.

Step2: Analyze symmetry/shape

The left side (lower values: 0 - 3) has fewer dots, right side (higher values: 6 - 8) also fewer, middle (4 - 5) more. It resembles a bell - shape (symmetric around the middle).

Step3: Check for outliers

No data points far from the main cluster, so no outlier.

Answer:

Bell - shaped, unimodal, no outlier
