Graphical representation refers to the use of charts and graphs to visually analyze and display, interpret numerical value, clarify the qualitative structures. The data is represented by a variety of symbols such as line charts, bars, circles, ratios. Through this, greater insight is stuck in the mind while analyzing the information. Show
Graphs can easily illustrate the behavior, highlight changes, and can study data points that may sometimes be overlooked. The type of data presentation depends upon the type of data being used. Graphical Representation of DataThe graphical representation is simply a way of analyzing numerical data. It comprises a relation between data, information, and ideas in a diagram. Anything portrayed in a graphical manner is easy to understand and is also termed as the most important learning technique. The graphical presentation is always dependent on the type of information conveyed. There are different types of graphical representation. These are as follows:
Also denoted as linear graphs are used to examine continuous data and are also useful in predicting future events in time.
This graph uses bars to represent the information. The bars represent the frequency of numerical data. All intervals are equal and hence, the width of each bar is also equal.
These are used to display the categories and compare the data using solid bars. These bars represent the quantities.
This table shows the frequency of data that falls within that given time interval.
It shows the frequency of data on a given line number.
It is also known as a pie chart and shows the relationship between the parts of the whole. The circle consists of 100% and other parts shown are in different proportions.
The diagram shows the relationship between two sets of data. Each dot represents individual information of the data.
It consists of overlapping circles, each depicting a set. The inner-circle made is a graphical representation.
The data is organized from the least value to the highest value. The digits of the least place value form the leaf and that of the highest place value form the stem.
The data is summarised by dividing it into four parts. Box and whisker show the spread and median of the data. Graphical Presentation of Data - DefinitionIt is a way of analyzing numerical data. It is a sort of chart which shows statistical data in the form of lines or curves which are plotted on the surface. It enables studying the cause and effect relationships between two variables. It helps to measure the extent of change in one variable when another variable changes. Principles of Graphical RepresentationThe variables in the graph are represented using two lines called coordinate axes. The horizontal and vertical axes are denoted by x and y respectively. Their point of intersection is called an origin ‘O’. Considering x-axes, the distance from the origin to the right will take a positive value, and the distance from the origin to the left will take a negative value. Taking the same procedure on y-axes. The points above origin will take the positive values and the points below origin will take negative values. As discussed in the earlier section about the types of graphical representation. There are four most widely used graphs namely histogram, pie diagram, frequency polygon, and ogive frequency graph. Rules for Graphical Representation of DataThere are certain rules to effectively represent the information in graphical form. Certain rules are discussed below:
Importance of Graphical Representation of DataSome of the importance and advantages of using graphs to interpret data are listed below:
What type of graphical representation that shows relationship and connection between information concepts and ideas?A concept map shows relationships between the main idea and other information. Concepts or ideas are represented in circles or boxes and are linked to related ideas with arrows.
What type of graphical representation shows relationship?Scatter plot -- a diagram that shows the relationship between two sets of data, where each dot represents individual pieces of data and each axis represents a quantitative measure.
Which graphic is a graphical representation of ideas and information?Infographics (a clipped compound of "information" and "graphics") are graphic visual representations of information, data, or knowledge intended to present information quickly and clearly. They can improve cognition by utilizing graphics to enhance the human visual system's ability to see patterns and trends.
What are the 4 graphical representation?This form of representation is seen in a frequency distribution that is represented in four methods, namely Histogram, Smoothed frequency graph, Pie diagram or Pie chart, Cumulative or ogive frequency graph, and Frequency Polygon.
