Histograms Graphs Math

Introduction:

       Let us learn about the histograms graphs in math. In mathematical concept of histogram is a graphical representation of given data records. It is easy way to understand the information by using different several of graph. A line graphs, bar graphs and pie graphs these are based on math Histogram graphs. Let us see graphs histogram functions.

Histograms graphs math:

Graphs are represented by title, bars, legend, axis (horizontal, vertical). These are important for graphs.

Title:Title is essential for graph because information (about histogram) is described by the title.
Bars: The bars have two essential characteristics, namely - height and width. The height explains the number of occurrences of values within an interval. The length of the interval covered by the bar is represented by the width.
Axis: axis is using for measured scale of values such as horizontal and vertical axis.
Legend: The legend provides extra information about the relation to the documents. These are important for histogram graphs.

Example for math histogram graphs:

        Let us learn about the frequency histogram graph in math. Frequency histogram graphs are easy methods to draw, at the same time we can clearly understand.

Column is represented for data range it divide into equal intervals.
Intervals are like (5-10, 11-15, 16-20……….) and another column for frequency.
Make a graph here data range intervals on horizontal axis but no space between intervals. And frequency percentages are we should mark on vertical axis this is also equal like horizontal axis.

Types of graphs:

  1. Area graphs
  2. Pie graphs
  3.  Line graphs
  4. Pictographs
  5. Bar graphs
  6. Frequency histogram graphs. These graphs are very clear to understand data records. Few of them as Follows.
Graphs:

X = 0-5  6-10  11-15  16 -20  21 -25  26 -30

Y =   10    20       30         40         50        60

Solution:

         Let us see bar frequency histogram graphs.



Line graphs:

X = 0    10  20  30  40  50

Y = 10  20  30  40  50  60

Solution: Let us see solution.
