The heights or length of the bar is proportional to the values.Ī line graph is a type of graph where the information or data is plotted as some dots which are known as markers and then they are added to each other by a straight line. They are as follows, Bar graphĪ bar graph or chart is a way to represent data by rectangular column or bar. There are many types of graph we can use to represent data. Because this type of data is loosely compact and can’t be analyzed conventionally.ĭifferent Types of Graphical Representations Qualitative data is also known as unstructured data. Discrete data can take only certain values by finite ‘jumps’, i.e., it ‘jumps’ from one value to another but does not take any intermediate value between them (For example, number of students in the class)ĭata that deals with description or quality instead of numbers are known as Quantitative data.There can be an infinite number of possible values in continuous data.Continuous data can take any numerical value (within a range) For example, weight, height, etc.Numerical data could be either discrete or continuous.Number of heads obtained in three tosses of a coinĭifferences between Discrete and Continuous data.Number of customers who visit at bank during any given hour.Number of complaints received at the office of airline on a given day.Number of fish caught on a fishing trip.Numbers of cars sold at a dealership during a given month.That means only a finite number can be categorized as discrete data. The time taken by a volunteer to perform a taskĭiscrete data can have certain values.The speed of a vehicle as it passes a checkpoint.That means Continuous data can give infinite outcomes so it should be grouped before representing on a graph. Continuous DataĬontinuous data is the data which can have any value. Quantitive data is again divided into Continuous data and Discrete data. Experiments, Tests, Surveys, Market Report. Quantitative data is also known as Structured data. The data which are statistical or numerical are known as Quantitive data. Here is a downloadable PDF to explore more. Data are the numerical information collected through observation. The graph is nothing but an organized representation of data. Then it is organized, summarized, classified, and then represented graphically.ĭifferences between Data and information: Data is the raw fact without any add on but the information is the meaning derived from data. The word data came from the Latin word Datum which means “something given”Īfter a research question is developed, data is being collected continuously through observation. Artists, illustrators, and others will find them still powerful as one of the landmarks of applied art.What are the different types of graphical representations? In addition to being marvelous renderings, these plates have long been noted for the peculiar emotional appeal that they have for most viewers, a premonition of surrealism with exotic organic life forms stretching back to their roots in the inorganic, and individual details drawn with awareness of subtle evolutionary changes and millennia-long developments. With many drawings on each plate, each carefully drawn from nature, the subtle details of nature's art forms are easily compared and appreciated. The Kunstformen contains 100 beautiful lithographic plates which show a multitude of unusual life forms: Radiolaria, Foraminifera, and other forms of microscopic life jellyfishes, starfishes, calcareous sponges, star corals, barnacles, and other sea life mosses, lichens, red algae, ferns, fungi, orchids, and other plants and turtles, moths, spiders, bats, frogs, lizards, hummingbirds, and antelope. These are the remarkable plates with which his work was illustrated, particularly his famous Kunstformen. Today, although no one is greatly interested in Haeckel the biologist-philosopher, his work is increasingly prized for something he himself would probably have considered secondary. His work was credited with having caused the acceptance of Darwinism in Europe, and his popular studies preaching the continuity of all life, organic and inorganic, from prehistoric time to the present converted tens of thousands of readers all over the world. Ernst Heinrich Haeckel (1834-1919) was renowned as one of the foremost early exponents of Darwinism.
