Charts and graphs provide a great deal of visual appeal. It can be used in the classrooms to present data, illustrate important patterns or relationships, and observe changes as data is altered.
Reasons to use Charts and Graphs:
Provide a visual representation of data;
Effectively clarify information;
Represents many different types of data;
Make important ideas easily recognizable;
Allow learners to perceive information quickly.
There are a lot of types of charts. Some of them are bar chart, pie chart, line chart, histogram, and etc.
A bar graph is a visual display used to compare the amounts or frequency of occurrence of different characteristics of data. [37] A bar chart makes the information clear and immediately visible to students. (see Example )
A pie graph is also called circle graph. It is a circular chart divided into sectors, illustrating numeral proportion. Pie graphs show the relationship of parts of a whole and always show how a whole is divided.
A line graph is a type of chart that is created by connecting a series of data points together with a line.
A histogram is similar to a bar chart in structure that organizes a group of data points into user-specified ranges.
Most of the charts and graphs shown above are very traditional. Data visualization is a hot field and there are many new forms of charts. We can also call it – graphic organizer. Graphic organizer is a visual display that demonstrates relationships between facts, concepts or ideas. Graphic organizers guide learners’ thinking as they fill in and build upon a visual map or diagram. Graphic organizers are some of the most effective visual learning strategies for students and are applied across the curriculum to enhance learning and understanding ...

... can be used both by teacher and students. It is easy to create mind map.
But even though mind maps in education have so much proven success, it is still only applied half-heartedly in mainstream education worldwide.

A person should be able to describe the monthly costs to operate a business, or talk about a marathon pace a runner ran to break a world record, graphs on a coordinate plane enable people to see the data. Graphs relay information about data in a visual way. If a person read almost any newspaper, especially in the business section, they will probably encounter graphs.
Answer: Graphs are necessary to study the general trends and have a quick look of the data; however, the summary indices are necessary to interpret results accurately. Graphical presentation is not that accurate as is the summary
Then, a scatterplot was formed with the data (Figure 3). It was a crucial graph as it helped determine the outliers in the information (see Appendix D for the outlier chart). Some of these outliers were located in towns with really low population numbers (the average population for an American city or town is around 20000)

For example, within the chapter titled “fauna” there is a pie chart which depicts the percentage of bones belonging to specific species out of the total amount of animal bones found in the tomb, thus far; the chart recounts to future researchers that the remains of Bos Taurus, or cow bones, were the most common type of animal remains found in the tomb by a margin of 40.9% (Weeks 2000: 129). Another example of data which was made more easily comprehendible via use of a table would be found within the chapter titled “pottery;” the table located on page 119 includes 3 columns which outline the chamber number, number of sherds excavated, and comments about characteristic majority from each chamber (Weeks 2000: 119). This type of data representation using graphs, charts and tables is valuable for future researchers as it creates a more readily available set of statistics on which one can draw conclusions, compare data from another site, and reference historical

My infographic is about some of the side effects Veterans come home with. In my infographic, it contains four charts. The charts my infographic contains are, a pie chart containing information about PTSD, a swatch chart with holding information about alcoholism, a triangle bar that has information about drug/ medication abuse, and a horizontal bar graph that encloses information about the number suicides.
I enjoyed Chapter 12 that covered Assessing and Planning Skills. When I was reading about Gantt charts I found them interesting – but at the time I was much more interested in the Pareto and Impact Analysis Charts. Perhaps my background in sales and marketing led to my attraction to those two types of charts over the Gantt chart. The Pareto chart immediately gave me solid numerical data and listed a breakdown of contributing factors. The example showed a school's climbing dropout rate. It gave a straight forward big picture view of the dropout rates for this school. The breakdown of contributing factors also gave the campus and school community clear targets for improvement such as more education and interventions in regards to drug and alcohol abuse and teen pregnancies. This chart to me quickly gave information and a suggested target plan. In sales and marketing this type of chart would have dictated targets for my advertising budget.
Lines are paths or marks left by moving points and they can be outlines or edges of shapes and forms. Lines have qualities which can help communicate ideas and feelings such as straight or curved, thick or thin, dark or light, and continuous or broken. Implied lines suggest motion or organize an artwork and they are not actually seen, but they are present in the way edges of shapes are lined up.
A subcomponent of written communication is visualizations. Visualizations as discussed earlier can be as simple as a picture or graph and most commonly used in aviation as maps and charts. Most newer aircraft display a moving map to increase situational awareness and geographical location of the aircraft. This visualization tool quickly and precisely indicates where the aircraft is located so
Finally, the first step in data handling is being able to sort your data into categories. Knowing how to sort and classify is obviously crucial to this process. Once the data has been sorted according to its different attributes it is then easy to represent it in a graph or table.
In fact, it is important to understand that: "The brain continues to be a new frontier. Our old way of schooling is fading fast as our understanding of the brain increases. Everything you do uses your brain, and everything at school involves students' brains.
32). The students are then able to visually keep up with their results and progress over a short or long period of time, which is then used as a motivational, visual tool. Not only does self-graphing aide in improving positive academic behaviors and habits, it also is, a contributing force for motivating students to improve due to the visual stimulus the graphing provides (p. 32). All of the student’s progression is laid out for them in one place, whether it is on a Microsoft Excel spreadsheet or a simple bar graph they draw themselves. Self-graphing is a great way to promote an increase is wanting to do better particularly in reading and writing. Teachers and students are also able to sit together and decided which graph would be best to satisfy the greatest amount of motivation. According to Hirsch, Ennis, and McDaniel (2013), self-graphing allows for flexibility in the since that if a student does not make their goal one week, they still have the option to make it the following week (p. 33). Hirsch et. al. (2013), suggest that setting up long term reading goals on a graph allows the students to visualize where they need to be at a specific time frame, providing motivation in a visual way (p. 33). If a child seems to struggle with behavior choices, self-graphing is a positive way to provide a visual
Assessments should be aligned to learning objectives. The assessment we administered was designed to measure students’ thinking about data. Common Core standard 3.MD.B3 asks students to draw a scaled graph to represent a data set with several categories. Solve one-and two-step “how many more” and “how many less” problems using information from the table (Council of Chief State School Officers, CCSS, 2010). The main purpose of this assessment was to evaluate student knowledge about graphs. We also wanted to know if students were able to compare and contrast information in the graph. We think that this is an important skill that students should be able to master. Students will encounter graphs while learning about other subjects. They must know how to collect data and use the information from gra...
Evidence from both educational journals and personal interviews suggest several different possible approaches to successful science integration. Many of the lesson plans dealt with integrating science with technology or with mathematics. For example, a fifth-grade teacher had his class record weather observations for an entire year and then used their data to teach graphing concepts including bar graphs, line graphs, pie charts, as well as concepts such as mean and mode (Chia, 1998).
