Mini Lesson
Data is information we collect. In a survey, we ask a question and record the answers. Tally marks help us count quickly — four upright lines and one diagonal across makes a group of 5. Then we can put the totals into a bar graph to compare the results easily.
Steps to Make a Bar Graph
- Survey: ask your family and friends "What is your favorite sport?"
- Record: use tally marks to count each answer.
- Count: total the tallies for each sport.
- Draw: draw a bar for each sport. The height of the bar shows the number of votes.
- Label: give your graph a title, label the x-axis (sports) and y-axis (number of people).
Reading a Bar Graph
- The tallest bar shows the most popular choice.
- The shortest bar shows the least popular choice.
- To find the total, add all the bar values together.
- To compare: "How many more chose X than Y?" Subtract the two values.
