Number of goalsFind the interquartile range (IQR) of the data in the dot plot. goals

To find the interquartile range (IQR) of the data in a dot plot, follow these steps:

1. Break Down the Problem

• Identify the data points represented in the dot plot.
• Determine the first quartile (Q1) and the third quartile (Q3).
• Calculate the IQR using the formula: $\text{IQR} = Q3 - Q1$

2. Relevant Concepts

• Quartiles divide the data into four equal parts.
  • Q1: The median of the first half of the data.
  • Q3: The median of the second half of the data.

3. Analysis and Detail

• List the data points from the dot plot in ascending order.
• Find the median of the lower half to determine Q1.
• Find the median of the upper half to determine Q3.

4. Verify and Summarize

• Calculate the interquartile range using the values of Q1 and Q3.

Final Answer

• After calculating, present the final result for the IQR succinctly.
