While accumulating data is essential to interpreting progress and making progress in future ventures, the ability to display data is critical. Displaying data allows for a superior understanding of the information. The three most common ways to visually display data is through the use of pie charts, bar charts, and line graphs. Pie charts are best used when comparing parts of a whole (Data Driven Decisions). A disadvantage of using a pie chart is that one will not be able to see changes over time. If one is trying to best track changes over time bar charts and line graphs will be used. When smaller changes exist, line graphs are better to use than bar graphs. Line graphs can also be used to compare changes over the same period of time for more than one group (How do I). Conversely, when trying to measure change over time, bar graphs are best when the changes are larger (How do I). Below is a chart with examples of data sets and the accompanying appropriate frequency chart.

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.

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)
The proliferation of graphic scores emerging in Europe and America from the mid-1950s has had a profound impact on musical thought, broadening links between performers and composers, audiences and art forms. Exploration of notational methods based on graphics flourished rapidly and diversely during the fifties and sixties, primarily as a trend amongst young radicals. So many composers producing scores of this kind used a personal vocabulary of symbols – often creating different notation systems for each work – that the effectiveness of their approaches in realising a sonic concept can be assessed only on a case-by-case basis. But the significance of early graphic scores does not depend entirely on how they sound; rather it lies in their capacity to accommodate or even to generate new forms, techniques and mediums, and to challenge notions of what constitutes a musical composition. In addition, these works demonstrate that notation can extend beyond instructional functionality to allow for prominent interpretive and aleatoric elements, and can harbour an intrinsic aesthetic value of its own, apparent before a single note is sounded.
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.
Now days, companies are searching for new ways of gathering data so that they can get useful data in order to make well informed decisions regarding the market they are operating in. Google analytics is considered one of the best tools offers extensive amount of data to business owners for free. However, the success of business is highly depended on how well they can arrange data and customize their collected data corresponded to their business priorities. Google analytics provides beneficial information for companies regardless of their extent of operation.
In evaluating statistical data one thing to consider is the measure that is used. By understanding the different statistical measurement tools and how they differ from one another, it is possible to judge whether a statistical graph can be accepted at face value. A good example is using the mean to depict averages. This was demonstrated by using the mean as a measure of determining the distribution of incomes. The mean income depicted was, $70,000 per year. At face value, it looks as though the sample population enjoys a rather high income. However, upon seeing individual salaries, it becomes obvious that only a few salaries are responsible for the high average income as depicted by the mean. The majority of the salaries were well under the $70,000 average. Therefore, the mean distributed income of $70,000 was at best misleading. By also looking at the median and mode measures of the income distributions, one has a clearer picture of the actual income distributions. Because this data contained extreme values, a standard deviation curve would have given better representation of salary distribution and would have highlighted the salaries at the high level and how they skewed the mean value.
Use appropriate tools that support data gathering (e.g. affinity diagram, brainstorming, fishbone, flowchart, force field, how-how, interrelationship digraph)
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
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...
Modern society heavily depends on the abilities of computers, Information Technology, and information processing. As such, since access to information occurs mainly through digital means and media, the way information is arranged and presented on the screen is crucial. Because of this need for fast access and easy arrangement arose, in the early 1980s, companies started to work on various graphical user interfaces (or GUI for short). Most dictionaries define a GUI as ‘a way of arranging information on a computer screen that is easy to understand and use because it uses icons, menus and a mouse rather than only text.’ Introducing such software allowed a human-computer interaction on a visual plane, and took computing to an entirely new level of experience. The first GUI started to emerge, as stated above, in the early 1980s, and within the last 3 decades have completely dominated the way in which human-computer communication occurs. Although some sources argue about it, it is acknowledged that the first company to use a proper graphical user interface was Apple. In 1984 they released the Macintosh computer, which used a graphical system to present information on the screen using boxes and taskbars, and utilized a revolutionary pointer device, now widely known as the mouse. Following this event, other companies started releasing their versions of GUI based operating systems, until in 1995 Microsoft presented Windows 95, which soon became a dominant power on the market, and along with its later installments, led Microsoft to be the IT giant of the 20th century. Since its appearance, the GUI have greatly influenced the IT-centered society, and the role computing and digital devices play in its growth.
One of the most popular types of charts is the pie chart. The pie chart is used to visually represent the proportional value of individual parts to the whole. As the name describes, this is done by representing the numerical equivalence of each part as a piece of the whole pie, which in total equates to 100%. The Pennsylvania Department of Health (2001) says that pie charts are a good choice when a relatively small amount of parts, perhaps 3 to 7, need to be represented. With any more it becomes difficult to notice the differences in magnitude; thus, the pie chart loses its simplicity and impact. They can only be used when a total amount is known, one such example would be an election where the total of votes received by all candidates equals 100% of the votes. Or a budget where the total amount spending is divided in to categories such as labor, facilities costs, advertising, etc… which always are a part of the total. However, according to McBride (2003), the pie chart could not be used to show a change in spending through out a period. A pie chart shows data at one instance, like a snapshot and cannot be used to show change in data over time (para. 4). With the advent of computers, 3D graphs have become somewhat popular, unfortunately a negative aspect is that they add complexity to the image and can distort visual proportional value. It is recommended to stick with flat “2D” charts (para. 6).
