Bar graphs are the pictorial representation of any kind of data that has been represented in the form of vertical or horizontal rectangular bars where everything will be proportional to the measure of data. These are also known as bar charts and are considered to be one of the best possible ways of handling data in the world of statistics.
The collection, presentation, analysis, interpretation and organisation of different kinds of observations of data is known as statistics and in this particular area bar graph plays a very important role because of the uniformity associated with it. All the bar graphs which are drawn are of uniform width and will be based upon variable quantity which will be represented on one of the axes and the measure of the variable will always be depicted on the other axis.
Following are the major attributes of the bar graphs:
- It can be perfectly used in terms of comparing different sets of data among different groups very easily
- It will help in showing the different relationship between two axes where the categories will be different and values will be discreet
- The graph will always help in showing the major and minor changes in the data over a specific period
Following are some of the very basic properties of the bar graphs:
- Every bar will be having a common base
- Every column in the bar graph will be of equal width
- The height of the bar should always be corresponding to the data value
- The distance between every bar will always be the same
- It can be perfectly utilised for matching different things between different groups and is also capable of tracking the changes over time
- Bar charts will always help in possessing a discrete domain of divisions which is normally skilled so that data can fit on the graph very easily.
Following are the most important advantages of the bar charts:
- It will help in summarising the large set of data into the simple visual form
- It will help in displaying every category of data into the frequency distribution
- It will be very much capable of clarifying the trend of the data in comparison to the tables and other options very easily.
- It will always help in estimating the key values at a glance without any kind of extraordinary efforts
Following are the basic steps to be followed by the kids at the time of drawing the bar graph:
- First of all, people need to decide the title of the bar graph
- Then kids need to draw the horizontal axis and the vertical axis
- Then labelling of the horizontal axis has to be carried out so that they can write the name of the horizontal axis very easily
- Now the labelling of the vertical axis has to be carried out
- After this kids need to finalise the scale range for the given data
- Finally, the drawing of a bar graph can be carried out so that it is very much capable of representing every category of the data with their respective numbers
Bar graphs are easily categorised into different kinds of categories and the primary feature of every kind of bar graph will be its height or length. If the length of the bar graph is more, then values will be greater than any kind of given data. These kinds of glass adorably showing the categorical and numeric values arranged into specific kinds of class intervals which will consist of different kinds of are the values. It can be perfectly categorised into different options like a vertical bar chart, horizontal bar chart, grouped bar chart, stacked bar chart and several other options depending upon the overall needs and requirements.
Hence, apart from this being clear about different other tools of statistics like pie chart, histograms and various other options is also very much important on the behalf of kids. The kids should register themselves on platforms like Cuemath so that they are always taught by the industry experts and everything has been perfectly carried out throughout their academic journey.
