The heights (in feet) and the number of stories of the ten tallest buildings in New York City are listed. Use a scatter plot to display the data. Describe any patterns. (Source: Emporis)
Verified step by step guidance1
Step 1: Organize the data into two variables: 'Height in feet' and 'Number of stories'. These will serve as the x-axis and y-axis for the scatter plot, respectively.
Step 2: Create a scatter plot by plotting each pair of values (height, stories) as a point on a Cartesian plane. For example, the first point would be (1776, 104), the second point (1550, 95), and so on.
Step 3: Label the axes of the scatter plot. The x-axis should represent 'Height in feet', and the y-axis should represent 'Number of stories'. Include appropriate units for clarity.
Step 4: Analyze the scatter plot for patterns. Look for trends such as whether taller buildings tend to have more stories, or if there are any outliers that deviate significantly from the general trend.
Step 5: Summarize the observed patterns. For example, you might note whether there is a positive correlation between height and the number of stories, or if the relationship appears non-linear or inconsistent.
