first bar graph: x axis - 0, 1, 2, 3, 4. Y axis: 1, 2, 3, 4, 0. No pets: 2. 1 Pet: 3. 2 pet: 4. 3 pet: 3. 4 pet. 2.
second bar graph x axis 0, 1, 2, 3, 4 Y axis 1, 2, 3, 4, 0. No pets: 0. 1 pet: 4. 2 pet: 3. 3 pet:4. 4 pet: 0.

Compare the graphs showing the number of pets each student in Mr. Bernhardt’s and Ms. Daniel’s classes has. In 3–5 sentences, state whether the distributions are symmetric and provide at least two similarities and two differences.

The distributions of the number of pets in Mr. Bernhardt’s and Ms. Daniel’s classes are not symmetric. In Mr. Bernhardt’s class, the highest frequency is seen at 2 pets, creating a left-skewed distribution, whereas in Ms. Daniel’s class, the distribution peaks at 1 and 3 pets, indicating a more bimodal shape.

Two similarities between the graphs are that both classes have students with no pets and that both classes exhibit a higher frequency of students with a smaller number of pets (1 or 2) compared to more pets. On the other hand, a primary difference is the peak number of pets—Mr. Bernhardt’s class has 2 pets as the most common, whereas Ms. Daniel’s class does not have any students with no pets and peaks at both 1 and 3 pets instead.
