Statistics graph:
Data recorded in surveys are displayed by a statistical graph. There are some specific types of graphs to study in the data statistics graphs. There are eleven type of graphs used in Data statistics graphs they are
Box plot,
Stem and leaf plot,
Frequency polygon,
Scatter plot,
Line graph,
Bar graph,
Histogram,
Pictograph,
Map chart,
Pie chart,
Line plot.
We take histogram for explaining about the statistics graph. A Histogram is a representation of frequency distribution through the four-sided figure whose width represents class intervals and whose areas are directly proportional to the corresponding frequencies.
Histograms will represent in Two Dimension used to graph continuous data. The histogram is used in continuous data graphing. This will be plotted continuously.
Example for statistics graphs
Construct the Data statistics graphs using Histogram.

A Bar chart is a pictorial representation of numerical data in the form of rectangles or Bars of equal widths and various heights. These rectangles are drawn either horizontally or vertically. It should be remembered that bar chart is of one dimension. The height of bar represents the frequency of the corresponding observation. The gap between two bars is kept the same.
Example for bar chart:
Here we are going to draw a bar chart for the attendance at different types if cultural events.
events |
Percentage of population |
Cinema |
56 |
Plays |
22 |
Art galleries |
21 |
Classical music |
12 |
Ballet |
7 |
Opera |
7 |
Other Dances |
5 |
The bar chart is drawn for the events and the percentage of population.
The event part contains Cinema, plays, art galleries classical music ballet opera and other dances. Now we are going to plot the bar chart for the given data.
