Math Problem Statement

How many students have a name with 6 letters? The graph represents the number of students with specific last name lengths using a dot plot.

Solution

The image shows a question about interpreting a dot plot labeled NAME LENGTH, which represents the number of students with a specific number of letters in their last names. The x-axis represents the number of letters (from 3 to 10), and the dots represent the number of students.

The question asks: How many students have a name with 6 letters?

From the dot plot:

  • The column above "6" has 5 dots.
    Thus, 5 students have names with 6 letters.

Would you like a detailed explanation of how to read the dot plot or explore related concepts?

Follow-up Questions:

  1. How can dot plots be used to summarize survey data?
  2. What are other types of visualizations for representing frequencies?
  3. How would the interpretation change if the question asked for names with "less than 6 letters"?
  4. How can you calculate the total number of students surveyed using the graph?
  5. What are the advantages of using a dot plot over a bar chart?

Tip:

When analyzing dot plots, remember that each dot corresponds to one observation or data point!
