Two graphs are shown for two different classes, showing their students’ number of pets.

Question

Pets in Mr. Bernhardt’s class:
2 students have 0. 3 students have 1. 4 students have 2. 3 students have 3. 2 students have 4.

Pets in Ms. Daniel’s class:
0 students have 0. 4 students have 1. 3 students have 2. 4 students have 3. 0 students have 4.

Compare the graphs showing the number of pets each student in Mr.
Bernhardt's and Ms. Daniel's classes has. In 3 short, simple sentences, state whether the distributions are symmetric and provide at least two similarities and two differences.

Answer 1

The distribution of pets in Mr. Bernhardt's class is not symmetric; it has a peak at 2 pets but tails off towards 0 and 4. In Ms. Daniel's class, the distribution is also not symmetric; it peaks at 1 and 3 pets with no students having 0 or 4 pets.

Similarities: Both classes have most students with 1 or 2 pets, and both distributions show a decline in the number of students as the number of pets increases.

Differences: Mr. Bernhardt's class has students with a wider range of pets, including those with 0 and 4, while Ms. Daniel's class has no students with 0 or 4. Additionally, the highest number of students in Mr. Bernhardt’s class is at 2 pets, whereas, in Ms. Daniel's class, the peak is split between 1 and 3 pets.
