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. ![]()
