![]() The horizontal axis is the X-axis and the vertical axis is the Y-axis. In a graph, there are two lines known as Axis or Coordinate axis. The principles of graphical representation are algebraic. Below there is a data table as well as a Scattergram as per the given data. The plot shows the relationship between two variables. Scatter diagram or scatter plot is a way of graphical representation by using cartesian coordinates of two variables. And each image represents a particular number of things.Īccording to the above-mentioned Pictograph, the number of Appels sold on Monday is 6x2=12. Pictograph or Pictogram is the earliest way to represents data in a pictorial form or by using symbols or images. ![]() A frequency distribution table is a graph or chart which shows the frequency of events. In the stem and leaf plot, each data is split into stem and leaf, which is 32 will be split into 3 stems and 2 leaves.įrequency table:Frequency means the number of occurrences of an event. The stem and leaf plot is a way to represents quantitative data according to frequency ranges or frequency distribution. It is a circular chart where numerical information represents as slices or in fractional form or percentage where the whole circle is 100%. The other name of the pie chart is a circle graph. With the histogram, each column represents a range of quantitative data when a bar graph represents categorical variables. Though it does look like a bar graph, there is a fundamental difference between them. The line graph is normally used to represent the data that changes over time.Ī histogram graph is a graph where the information is represented along with the height of the rectangular bar. 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. What are the different types of graphical representations?
