How to Make a HistogramHow to Make a Histogram
The study of mathematics can be sub categorized into different categories like geometrical
mathematics, elementary mathematics and so on.
In the same aspect the study of graph can be consider as a type of geometry that helps in
solving the problems which are related to real world.
Generally the concept of graph is used to represent the sample data or records in the
visualized form. The numerical sample data in a pictorial format provide lots of help in real life.
In the mathematical definition graph can be expressed as a way to diagrammatical
representation of data perform the task of evaluation or analyze the large amount of data in a
simple form. The concept of graph helps in representing the sample data values.
In geometry various categories of graphs are defined like pie charts, bar graphs and
histogram and line graph. The different categories of graphs have three different work area
like bar graph is used for data that are represented in the form of rectangular bars with
corresponding to the y - axis. Know More About :- Static Friction Math.Tutorvista.comPage No. :- 1/4
In the same aspect histogram works on x and y axis of graph to represent the data values in
different range category.
This category of graph it means histogram is popularly used for representing the frequency
range of the graph. In mathematics, frequency of the data can be refers as number of same
data values in the records.
In histogram, these are represented by using the concept of rectangle whose widths represent
the class interval and whose height is proportional to the corresponding data frequencies. In a
first look histogram looks like a bar graph but the basic difference is that in histogram x axis
and y axis play the role of representing the data value and their frequencies.
Histograms are popularly used for only those type of data that contains the frequencies
sample data. It means that histogram depended on the scale value of x-axis and y-axis.
Especial y x- axis of histogram contains the frequency value like 10 to 20 or 20 to 30 and so
on. On the other hand y- axis deals with the simple scale value in the histogram, whose value
depended on the user.
here we are going to discussing about How to Make a Histogram. To perform that task of How
to make histogram requires some of the steps that need to be follow:
( a) In the first step perform the analysis of sample data. The sample data with their frequency
performs the creation of histogram. Mostly frequency range of sample data need to be
calculated by creating the tally table on available data, after that calculate the frequency of
( b) On the basis of tal y table, we need to perform the calculation of different range value of
the sample data.
(c) The label of the histogram graph should be clear and accurate, which must be specific to
describe the goal of the graph.Learn More :- Fluid Dynamics Math.Tutorvista.comPage No. :- 2/4
(d) On the basis of sample data perform the analysis of the scale value of the x- axis and y-
axis. The calculated frequency value should be put on the x axis of the histogram.
(e) At last manage the rectangular bars according to the sample data and their frequencies.How to Make a Histogram
The following steps are to be fol owed to construct a histogram.
(1) Mark class intervals on X-axis and frequencies on Y-axis.
(2) The scales for both the axes need not be the same.
(3) Class intervals must be exclusive. If the intervals are in inclusive form, convert them to the
(4) Draw rectangles with class intervals as bases and the corresponding frequencies as
(5) The class limits are marked on the horizontal axis and the frequency is marked on the
vertical axis. Thus, a rectangle is constructed on each class interval.
(6) If the intervals are equal, then the height of each rectangle is proportional to the
corresponding class frequency.
(7) If the intervals are unequal, then the area of each rectangle is proportional to the
corresponding class frequency. Math.Tutorvista.comPage No. :- 4/4
