What will you learn in this lesson?

In this lesson we learn to collect data with a survey, organize it in a tally chart and a frequency table, and read a line plot. Organized data answers questions like: Which color is the favorite?

  • Collects data with a survey and records it with tally marks
  • Organizes data in a frequency table
  • Reads and interprets a line plot
  • Finds the mode and range of a data set

💡 Tip: In a tally chart, draw every five tallies as one bundle (four lines and a fifth slanted across them), so counting by fives is faster and more accurate.
