Which of the following statements is supported by the bar chart?
Understand the Problem
The question is asking which statement about the woodpecker damage is supported by the bar chart provided. It requires analyzing the chart to determine relationships among the types of siding and the proportions of holes created for different types of damage.
Answer
C: The proportion of holes created for drumming is least for grooved plywood.
Answer for screen readers
The correct answer is C: The proportion of holes created for drumming is least for grooved plywood.
Steps to Solve
-
Examine the Bar Chart Analyze the bar chart carefully, paying attention to the relative frequencies of the different types of damage (drumming, foraging, nesting) for each siding type (Clapboard, Grooved Plywood, Nonwood).
-
Identify Proportions of Drumming Look specifically at the black colored sections of the bars, which represent the proportion of holes created due to drumming for each type of siding. Compare these proportions.
-
Compare Frequent Damage Types Determine which type of siding has the highest and lowest proportions of holes due to drumming. This will help in identifying any statements about the greatest and least occurrences of drumming.
-
Evaluate Each Statement Review each answer option (A-E) against the observations from the chart. Check if the statements reflect the data shown, particularly focusing on the proportions for drumming in each siding type.
-
Select the Correct Statement Choose the statement that accurately reflects the information obtained from the bar chart related to the damage types and siding materials.
The correct answer is C: The proportion of holes created for drumming is least for grooved plywood.
More Information
The bar chart illustrates the different types of damage inflicted by woodpeckers across three types of siding. It shows that among the various siding types, the grooved plywood has the lowest relative frequency of holes created due to drumming.
Tips
- Misreading the sections of the bars: Ensure to identify the correct color associated with drumming.
- Failing to compare all three types of siding: It's crucial to evaluate all siding types rather than just focusing on one.
- Not considering proportions: The question asks for proportions, not absolute counts of holes, which could lead to incorrect interpretations.
