## Understanding Statistical Graphs: A Research Survey

Graphs and charts can make it easier for people to interpret information. There are many types of graphs and charts that organize data in different ways, and they are commonly used for business purposes. It is important to know the different types of graphs and charts so you can choose the best one to display your information, especially when making professional presentations.

In this article, we will discuss various charts, graphs and their various uses. Graphs and charts are visuals that show relationships between data and are intended to display the data in a way that is easy to understand and remember.

People often use graphs and charts to demonstrate trends, patterns and relationships between sets of data. Graphs may be preferable to display certain types of data, while charts are ideal for others. Charts are tables, diagrams or pictures that organize large amounts of data clearly and concisely. People use charts to interpret current data and make predictions. You can choose from many types of graphs to display data, including:.

Line graphs illustrate how related data changes over a specific period of time. One axis might display a value, while the other axis shows the timeline. Line graphs are useful for illustrating trends such as temperature changes during certain dates. Bar graphs offer a simple way to compare numeric values of any kind, including inventories, group sizes and financial predictions.

Bar graphs can be either horizontal or vertical. One axis represents the categories, while the other represents the value of each category. The height or length of each bar relates directly to its value. Marketing companies often use bar graphs to display ratings and survey responses. A pictograph uses pictures or symbols to display data instead of bars.

Each picture represents a certain number of items. Pictographs can be useful when you want to display data in a highly visual presentation such as an infographic. For example, you could use a picture of a book to display how many books a store sold over a period of a few months. A histogram is another type of bar graph that illustrates the distribution of numeric data across categories.

People often use histograms to illustrate statistics. For example, a histogram might display how many people belong to a certain age range within a population.

The height or length of each bar in the histogram shows how many people are in each category. Area graphs show a change in one or more quantities over a certain period of time.

They often help when displaying trends and patterns. Similar to a line graph, area graphs use dots connected by a line. However, an area graph involves coloring between the line and the horizontal axis.

You can use several lines and colors between each one to show how multiple quantities add up to a whole. For example, a retailer might use this method to display the profits of different stores over the same timeframe.

Scatter plots use dots to depict the relationship between two different variables. The process involves plotting one variable along the horizontal axis and the other variable along the vertical axis. The resulting scatter plot demonstrates how much one variable affects the other. If there is no correlation, the dots appear in random places on the graph.

If there is a strong correlation, the dots are close together and form a line through the graph. There are seven common charts you can use to display information:. Flowcharts help organize the steps, decisions or actions in a process from beginning to end.

They often include more than one starting point or endpoint, displaying different paths you can take in a process to get from start to finish. People often use flowcharts to depict complex situations. They use special shapes to illustrate different parts of the process, and they typically include a legend to explain what each shape means.

A pie chart presents the different parts of a whole. It looks like a circle divided into many pieces, much like a pie cut into slices. The pieces are different sizes based on how much of the whole they represent. Each piece usually has a label to represent its value compared to the whole. Professionals can use pie charts in business presentations to demonstrate population segments, market research responses and budget allocations.

Gantt charts illustrate project schedules. The horizontal axis represents the timeframe for the project in days, weeks, months or years. The chart displays each project task as a bar on the vertical axis. The length of the bar depends on the start and end date of the task, but sometimes there is also a vertical line for the current date. Project managers use Gantt charts to monitor the progress and completion status of each task.

Waterfall charts reflect variance over time. They demonstrate both the positive and negative impact of different factors on an initial value, such as an opening balance.

Waterfall charts are helpful when illustrating financial statements, analyzing profit and loss and comparing earnings. You might use this chart to highlight the budget versus the amount spent. Positive and negative values usually follow a color code to show how the value increases or decreases due to a series of changes over time.

Gauge charts display data as a reading on a dial. They show where a specific data point is within a minimum or maximum range. A needle depicts the value within a scale. Many people use gauge charts to illustrate speed, revenue goals and temperatures. Funnel charts illustrate how values progress through different stages. They are widest at the top and narrowest at the bottom.

Funnel charts are especially helpful when tracking a sales process. They also work well to depict website traffic, including the number of visitors to a site, the pages viewed and downloads made. A bullet chart can help you measure the performance of a specific goal or target.

Some bullet charts, such as those that demonstrate profits, have high targets. Others have low targets, including those that display expenses.

A bullet chart is similar to a bar graph and consists of three parts:. Skip to main content Indeed Home. Find jobs Company reviews Find salaries.

When dealing with numbers in statistics, incorporating data visualization is integral to creating a readable and understandable summary of a dataset. There are, however, numerous types of graphs and charts used in data visualization and it is sometimes tricky choosing which type is best for your business or data. Each of these graphs has its own strengths and weaknesses that make it better than others in some situations.

A pie chart or a circle chart is a circular statistical graphic , which is divided into slices to illustrate numerical proportion. In a pie chart, the arc length of each slice and consequently its central angle and area , is proportional to the quantity it represents. While it is named for its resemblance to a pie which has been sliced, there are variations on the way it can be presented. The earliest known pie chart is generally credited to William Playfair 's Statistical Breviary of Pie charts are very widely used in the business world and the mass media.

One goal of statistics is to present data in a meaningful way. This is far too many to print out in a journal article or sidebar of a magazine story. That's where graphs can be invaluable, allowing statisticians to provide a visual interpretation of complex numerical stories. Seven types of graphs are commonly used in statistics. Good graphs convey information quickly and easily to the user.

В глазах Сьюзан Дэвид был самим совершенством - насколько вообще такое .

Хейл же был уверен, что галит - некий драгоценный камень, поэтому считал, что это прозвище вполне соответствует его выдающимся умственным способностям и прекрасному телосложению. Будь он менее самонадеян, он, конечно же, заглянул бы в энциклопедию и обнаружил, что это не что иное, как солевой осадок, оставшийся после высыхания древних морей. Как и все криптографы АНБ, Хейл зарабатывал огромные деньги, однако вовсе не стремился держать этот факт при. Он ездил на белом лотосе с люком на крыше и звуковой системой с мощными динамиками.

Она знала, что он перемножает цифры и намертво запоминает словари, не хуже ксерокса. - Таблица умножения, - сказал Беккер. При чем здесь таблица умножения? - подумала Сьюзан. - Что он хочет этим сказать. - Четыре на шестнадцать, - повторил профессор.

- Что же это за цикличная функция, над которой три миллиона процессоров бьются уже шестнадцать часов. Он постоял в нерешительности, раздумывая, не следует ли поставить в известность начальника лаборатории безопасности. Да будь они прокляты, эти криптографы. Ничего не понимают в системах безопасности.
