  2. Learn to use tables to record and organize data.

  3. A table contains numbers or quantities (data) arranged in rows and columns. • Make sure to give your table a title where people will know what your data is about. • Make sure to label your columns and rows where people can easily read and interpret data.

  4. Additional Example 1: Application Use the audience data to make a table. Then use your table to describe how attendance has changed over time. On May 1, there were 275 people in the audience at the school play. On May 2, there were 302 people. On May 3 there were 322 people. Make a table. Write the dates in order so that you can see how the attendance changed over time. 275 302 322 From the table you can see that the number of people in the audience increased from May 1 to May 3.

  5. Check It Out: Example 1 Use the audience data to make a table. Then use your table to describe how attendance has changed over time. On April 1, there were 212 people at the symphony. On May 1, there were 189 people. On June 1 there were 172 people. Make a table. Write the dates in order so that you can see how the attendance changed over time. 212 189 172 From the table you can see that the number of people in the audience decreased from April 1 to June 1.

  6. Additional Example 2: Organizing Data in a Table Use the temperature data to make a table. Then use your table to find a pattern in the data and draw a conclusion. At 3 A.M., the temperature was 53°F. At 5 A.M., it was 52°F. At 7 A.M., it was 50°F. At 9 A.M., it was 53°F. At 11 A.M., it was 57°F. 53 52 50 53 57 The temperature dropped until 7 A.M., then it rose. One conclusion is that the low temperature on this day was 50°F.

  7. Check It Out: Example 2 Use the temperature data to make a table. Then use your table to find a pattern in the data and draw a conclusion. At 2 A.M., the temperature was 48°F. At 4 A.M., it was 46°F. At 6 A.M., it was 44°F. At 8 A.M., it was 47°F. At 10 A.M., it was 51°F. 48 46 44 47 51 The temperature dropped until 6 A.M., then it rose. One conclusion is that the low temperature on this day was 44° F.

  8. Lesson Quiz 1.Humans have the following approximate heart rates at the ages given: newborn, 135 beats per minute (bpm); 2 years old, 110 bpm; 6 years old, 95 bpm; 10 years old, 87 bpm; 20 years old, 71 bpm; 40 years old, 72 bpm; and 60 years old, 74 bpm.
