Line plot examples using whole numbers

📚 Quick Study Guide

• 📈 A line plot is a graph that shows the frequency of data along a number line.
• 🔢 It uses 'x' marks (or other symbols) above a number to show how many times that number appears in a data set.
• 📊 Line plots are helpful for quickly seeing the distribution of data and identifying outliers or clusters.
• 📏 To create a line plot:
  • 📝 Draw a number line that includes all the numbers in your data set.
  • 📌 For each number in the data set, place an 'x' above that number on the number line.
  • 🔑 The more 'x's above a number, the more frequently that number appears in the data.
• ➕ The data used in line plots is usually whole numbers, making it easy to visualize counts.
