# Statistical Graphs

Statistics graphs are a ways to represent Statistics data in pictorial figure because numerical figures are more noticeable and easily intelligible, leaving a more lasting effect on the mind of the observer. With the help of these statistics graphs, data can be compared easily. There are many types of statistics graphs that exist in mathematics. A few of them are Bar Graph, Histograms Frequency Polygon, etc.

Now let us discuss these graphs briefly -
In a bar graph, bars of uniform width are drawn with various heights. The height of a bar represents the frequency of the corresponding observation.
A histogram is the Graphical representation of a frequency distribution in the form of rectangles with class intervals as bases and the corresponding frequencies as heights, there being no gap between any two successive rectangles.
In Frequency Polygon graph, we compute the diagram in the form of a polygon by taking two more classes (called imagined classes), one at the beginning and the other at the end.
These are few types of Statistical graphs and we use them in different problems. For instance, if we want to calculate highest frequency, we use bar graph and if we want to draw frequency distribution, we use Histograms and if we want to calculate frequency of a particular class, we use polygon graphs.

## Frequency Polygon

A graph which is used for understanding the shapes of distributions is known as a frequency Polygon. A frequency polygon works as histogram; it is useful for comparing the Sets of data. A graph line is drawn by joining al...Read More

## Bar Graph

There are different methods to represent the collected data on the graph. Some of the common methods we use are, line graph, bar graph, histogram, pie charts and many more. A bar graph is a chart with rectangular bars placed vertically or horizontally on the ‘x’ or ‘y’ axis. Depending on their placement they are either call vertical bar graph or horizontal bar graphs.  They he...Read More

## Frequency Histogram

In the statics, the information can be represented by the help of a frequency histogram. In the histogram graph the rectangles are used to show the frequency of data items in form of successive intervals. The independen...Read More

## Pie charts

The graphs can be represented in different ways as per the need and the requirement of the presentation. Some of the Common Graphs are Bar Graph, line graph, histogram, pie chart etc. A pie chart is also called as circular chart, where the whole graph is divided into sectors of different angles. While representing the pie chart, we observe that the Arc Length of each sector, ...Read More

## Ogive

Graphs are the best way to show the relationship between two variables. The frequency distribution graphs are frequency graphs and are used to define the characteristic which is more trust worthy than the tabulated form or other sour...Read More

## Box Plots

Box plots in Statistics are methods of representing numerical data graphically. They consist of 5 parts:
1.      Small observation
2.      Lower quarter
3.      Median
4.      Upper quarter
5.      Large observation
Boxplots also tell about the Numbers which are away from numerical data. Boxplots are mainly used to describe differences of population without considering s...Read More

## Stem and Leaf Plots

It is not easy to analyze large amount of data by manually. So, for resolving these kind of problems, we use graphical, statistical and Probability methods, which are called as a steam and leaf plot. With the help of stem leaf plot, we can easily find out relative density and value of particular data, means we can easily summarize data with the help of stem and leaf ...Read More

## Cumulative Frequency graphs

It is very easy to understand data graphically view rather than mathematical view. So, for representing large amount of data we use different graphical methods in Probability and Statistics. Here we discuss a graphical method which is related with frequency and when we create this graphical plot, then this plot is called as a cumulative frequency graph. With ...Read More

## Organizing Experiment Data

We can say that the experiment data is the Set of raw data arranged in the organized form. With a view to start analysis, we first require data which is further processed, so we say that the collection of data is basically needed for any statistical study.

We say that organizing experiment data is necessary to come to certain conclusions, so the collected ...Read More

## Histograms

We represent our data in different forms of graph which help us to predict and come to easy and fast conclusions. While giving the diagrammatic and pictorial presentation of the data we use different types of figures and charts. All these methods are non quantitative modes of presentation of the data but they are the perfect way to analyze. This is done by the visual presenta...Read More

## Bar Graph Definition

Bar graph is an important part of Statistical graphs and according to Statistics; Bar graph is a pictorial representation of statistical data. Bar graph definition suggests that the independent variable in a Bar Graph can accommodate only few discrete values while the dependent variable may be continuous and discrete as well. The column graph or vertical bar graph i...Read More
