Question

a scientist wants to display the number of chirps that were recorded in a one - hour period for three different species of songbird. what type of visual display should the scientist use?
a. a line graph
b. a bar graph
c. a musical staff
d. a circle graph

Explanation:

Step1: Analyze each option

• Line graph: Used to show trends over time. But here it's about comparing counts of different species (not a time - related trend).
• Bar graph: Ideal for comparing discrete categories (like different songbird species) and their corresponding values (number of chirps).
• Musical staff: Used in music notation, not for data display.
• Circle graph: Used to show parts of a whole. But the problem is about comparing separate entities (species), not parts of a single whole.

Answer:

B. A bar graph
