Explanation:
Katie is a member of the Young Entrepreneurs and she must present a proposal for a summer job. She decides to operate an ice cream stand during summer vacation. If her proposal is chose as the one “most likely to succeed” then her startup costs will be covered by the Young Entrepreneurs. Katie begins by asking people to name their favorite ice cream flavor.
The results of her survey are displayed on the following bar graph.Bar Graphs
In the real world, you are expose to data every day. If you watch the weather forecast on TV you are presented with information about the weather for the day as well as information about the weather for the entire week ahead. When you receive your report card you are given data about your marks and your attendance.
Data is simply collected information. This information often takes the form of a collection of numbers which can be visually displayed in a table or on a graph.
When you conduct a survey, measure how changes occur over time or study changes in trends, the recorded information is data. The data should be analyzed, organized and visually displayed. One type of visual display is a bar graph.
A bar graph is probably the type of graph that you have worked with most often over the years. Do you remember what a bar graph is and what purpose it serves as a visual display of information?
A bar graph is a visual way of showing information in which quantities corresponding to particular categories are represented by rectangular bars of equal width. The lengths or heights of the rectangular bars compare the quantities in different categories.
If you are going to display your recorded data using a bar graph then the graph must have a title clearly stating what the graph is about. One axis of the chart must be labeled so as to show the categories being compared and the other axis must have a label and a suitable scale to represent the quantity being displayed. A bar graph can have either vertical bars or horizontal bars.
Below is a bar graph representing the average monthly rainfall in the capital city for the first six months of the year 2014.In the above bar graph the title is clearly shown above the graph and both axes are labeled. The vertical bars compare the average amount of rainfall for each of the six months. This same bar graph can also be displayed using horizontal bars as shown below.Remember that a bar graph displays collected data and this data can lead you to discussions and allow you to draw conclusions. Let’s use the above bar graph to answer some questions.
In which month did the most amount of rain fall?
First, look at the horizontal bars on the graph and find the longest bar. The longest bar is the one that extends farthest to the right.
Then, look to the left of this longest bar to see the month represented by this bar.
The answer is May.
What was the average rainfall for the month of February?
First, look on the vertical axis and find the month of February.
Next, follow the horizontal bar for this month to the right until you reach the end of the bar.
Then, find the value on the horizontal axis labeled ‘Rainfall (mm)’ that corresponds with the end of the bar.
The answer is 65 mm.
Which month had the lowest average rainfall?
First, look at the horizontal bars on the graph and find the shortest bar. The shortest bar is the one that extends least to the right.
Then, look to the left of this longest bar to see the month represented by this bar.
The answer is June.
