Some of them are as follows: Line Graphs – Line graph or the linear graph is used to display the continuous data and it is useful for predicting future events over time. Graphical representation is the visual display of data using plots and charts. The type of data often determines what graph is appropriate to use. Line Graphs. It is often more effective than presenting data in tabular form. The size of slices varies upon the data. MEMORY METER. Most of the time, the statistics data sets contain massive amounts of values. Types of data and graphical representation 1. You can either represent the data horizontally or vertically. Apart from that, it offers you the best way to represent and conveniently compare the complex data sets. It is the statistics chart to uncover the potential of the dataset. So if there is a priority for accuracy, we have to recommend tabulation. In the scatterplot, the lines or curve is used to show the data. Bar charts, histograms, pie charts, and boxplots (box and whiskers plots). A chart can represent tabular numeric data, functions or some kinds of quality structure and provides different info. Ø Graphical Representation: It is the representation or presentation of data as Diagrams and Graphs. It is used in many academic and professional disciplines but most widely so in the fields of mathematics, medicine and the sciences. If the classes contain the lower frequencies, then it would have the shorter as compared with the taller ones that contain, the higher frequency. This graph breaks each value of a quantitative data set into two pieces. Furthermore, any hidden trend present in the given data can be noticed only in this mode of representation. Graphical Data Analysis in R. R is believed to be the best at data visualization for good reason. In a graph there are two lines called coordinate axes. HISTORY. It was developed in the early 1900s by Vilfredo Pareto. R base packages come with functions like the hist() function, the boxplot() function, the barplot() function, etc. In graph theory, a graph representation is a technique to store graph into the memory of computer. Ordinal values are not easily measured i.e., feelings, opinions, suggestions. While in the histogram, the data with ordinal values are the primary factor. Visit http://ilectureonline.com for more math and science lectures! There are different types of graphical representation. You can get the idea of the relationship between data with the help of graphs. The histogram is another best statistics graph to represent the data. Most of the experts say that it is a hybrid of the histogram and a stem and leaf plot.

He used this graph to conduct his study on wealth and poverty. … If you are still finding it challenging to choose the right graph, let our statistics experts help you in this to choose the best statistics graph for your dataset. The universally-recognized graph features a series of bars of varying lengths.One axis of a bar graph features the categories being compared, while the other axis represents the value of each. A circle graph is also known as Pie charts. 12.15 Points for Discussion 12.16 Answers to Check Your Progress 1 12.17 Suggested Readings I 12.1 INTRODUCTION In Block 11, you have studied about the learner's … It is usually used in statistics, business plans, feasibility studies, web analytic and more. Every type of graph is a visual representation of data on diagram plots (ex. Line or Dot Plots Line plots are graphical representations of numerical data. Here we discuss the introduction, components, types of graph, with two most generic ways of representing a graph. In this section we describe some graphical presentations of data. For example, $4 could be represented by a rectangular bar fou… Since a cumulative frequency is either of a ‘less than’ or a ‘more than’ type, Ogives are of two types too – ‘less than ogive’ and ‘more than ogive’. By the frequency of a number we mean the number of … What you will learn?

The variation of terrorism in Pakistan is usually seen in the form of figures I.e. A cumulative frequency curve or Ogive is the graphical representation of a cumulative frequency distribution. Ø In graphical data representation, the Frequency Distribution Table is represented in a Graph. In contrast, qualitative and quantitative data use different types of charts.
