Interpreting Bar Graphs Examples
Example 1.
Evaluate the below bar graph and answer the following questions. The below bar graph compares the lunch options available in the college cafeteria to the number sold during one week.
(i) How many sandwiches sold out from the Cafeteria lunch menu?
(ii) Which item sold high in between Chicken Burger and Taco Wrap?
(iii) Which item sold less in the Cafeteria lunch menu?
Solution:
Given Cafeteria lunch menu is
Caesar Salad – 45
Taco Wrap – 80
Sandwiches – 65
Soup – 75
Chicken Burger – 95
Daily Special – 115
(i) 65 sandwiches are sold out from the Cafeteria lunch menu.
(ii) Chicken Burger – 95 and Taco Wrap – 80
95 > 80.
Therefore, Chicken Burger is the most purchased from the Cafeteria lunch menu compared to Taco Wrap.
(iii) Caesar Salad items sold less in the Cafeteria lunch menu.
Example 2.
The Given bar graph is often drawn with two or more bars in each category. The following bar graph shows the temperature in degrees Fahrenheit for the third week of May for the years 2001 and 2016 respectively. Observe the bar graph to answer the questions presented below the graph.
(i) What was the highest recorded temperature in the year 2001?
(ii) What is the lowest temperature recorded for the year 2016?
(iii) What is the average daily temperature for the week displayed on the bar graph for each year?
Solution:
The temperature in degrees Fahrenheit for the third week of May from the years 2001 and 2016.
(i) The temperatures recorded in the 2001 year are 57, 53, 66, 55, 70, 59, 68.
70 is the highest temperature.
Therefore, the highest recorded temperature in the year 2001 is 70 degrees Fahrenheit.
(ii) The temperatures recorded in the 2016 year are 64, 71, 62, 68, 70, 65, 60.
60 is the lowest temperature.
Therefore, the lowest recorded temperature in the year 2016 is 60 degrees Fahrenheit.
(iii) The average daily temperature for the week displayed on the bar graph for each year is
The answer is 61.1 degrees Fahrenheit for the year 2001.
The answer is 65.7 degrees Fahrenheit for the year 2016.
Example 3.
Sam asked some students how they traveled to school. She drew this bar chart to show the results.
(i) Which method of travel was used most by the students?
(ii) How many students did Sam ask in total?
(iii) How many more students walked to a school than cycled to school?
Solution:
Given that some students traveled to school.
(i) The most used method of traveling to school is Walking.
(ii) To find out the total number of students, add the amount.
4 + 6 + 9 + 5 + 1 = 25 students in total.
(iii) Students who walked = 9.
Students who cycled = 4.
To find out how many more you do by subtracting the number of students who cycled from Students who walked.
9 – 4 = 5 more students walked than cycled.
