  2. 6-4 Bar Graphs Course 1 Warm Up Use the following data set. 45 55 58 63 63 37 76 46 34 1.What is the mean of the data? 2. What is the median of the data? 3. What is the mode of the data? 53 55 63

  3. 6-4 Bar Graphs Course 1 Problem of the Day The distance around the bases is 4 × 90 feet. How many runs does a baseball team need to score before the scoring base runners have covered a mile? (1 mile = 5,280 feet) 15 runs

  4. 6-4 Bar Graphs Course 1 Learn to display and analyze data in bar graphs.

  6. 6-4 Bar Graphs Course 1 A bar graph can be used to display and compare data. A bar graph displays data with vertical or horizontal bars.

  7. 6-4 Bar Graphs Course 1 Additional Example 1A: Reading a Bar Graph Use the bar graph to answer each question. A. Which biome in the graph has the lowest average summer temperature? Find the lowest bar. The coniferous forest has the least average summer temperature.

  8. 6-4 Bar Graphs Course 1 Additional Example 1B: Reading a Bar Graph Use the bar graph to answer each question. B. Which biomes in the graph have an average summer temperature of 30C or greater? Find the bar or bars whose heights measure 30 or more than 30. The grassland and the rain forest have average summer temperatures of 30C or greater.

  9. 6-4 Bar Graphs Course 1 Try This: Example 1A Use the bar graph to answer each question. A. Which biome in the graph has the highest average summer temperature? Find the highest bar. The rain forest has the highest average summer temperature.

  10. 6-4 Bar Graphs Course 1 Try This: Example 1B Use the bar graph to answer each question. B. Which biomes in the graph have an average summer temperature of 25C or greater? Find the bar or bars whose heights measure 25 or more than 25. The deciduous forest, the grassland, and the rain forest have average summer temperatures of 25C or greater.

  11. 6-4 Bar Graphs Course 1 Additional Example 2: Making a Bar Graph Use the given data to make a bar graph. Step 1:Find an appropriate scale and interval. The scale must include all of the data values. The interval separates the scale into equal parts. Step 2:Use the data to determine the lengths of the bars. Draw bars of equal width. The bars cannot touch. Step 3: Title the graph and label the axes.

The scale must include all of the data values. The interval separates the scale into equal parts. Step 2:Use the data to determine the lengths of the bars. Draw bars of equal width. The bars cannot touch. Step 3: Title the graph and label the axes.

  13. 6-4 Bar Graphs Course 1 A double-bar graph shows two sets of related data.

  14. 6-4 Bar Graphs 1 2 Course 1 Additional Example 3: Problem Solving Application Make a double-bar graph to compare the data in the table. Understand the Problem You are asked to use a graph to compare the data given in the table. You will need to use all of the information given. Make a Plan You can make a double-bar graph to display the two sets of data.

  15. 6-4 Bar Graphs 3 Solve 4 Course 1 Additional Example 3 Continued Determine appropriate scales for both sets of data. Use the data to determine the lengths of the bars. Draw bars of equal width. Bars should be in pairs. Use a different color for boy memberships and girl memberships. Title the graph and label both axes. Include a key to show what each bar represents. Look Back You could make two separate graphs, one of boy memberships and one of girl memberships. However, it is easier to compare the two data sets when they are on the same graph.

Club Memberships Memberships Club Look Back You could make two separate graphs, one of boy memberships and one of girl memberships. However, it is easier to compare the two data sets when they are on the same graph.

  18. 6-4 Bar Graphs Course 1 Insert Lesson Title Here Lesson Quiz: Part 1 Use the bar graph to answer each question. 1. Which animal was least popular among students? 2. Which pet was more popular to twice as many students as rabbits were? Student Pet Survey bird dog
