If the data does not change continuously, it is called discrete data, and is commonly compared by use of a bar chart.
Technical note: please note the use of the word chart, graph is commonly misused in a mathematical sense like this. A graph, mathematically, is a series/group of nodes that represent information and are connected by lines/edges that represent a link to other information. Bar graphs, line graphs, histogram graphs, bubble graphs, area graphs etc, are all technically chartsnot graphs. For more info see the link below on graph theory.
Bar graph :)
Any graph can be used for such a purpose.
A bar chart is a term for bar graph. A bar graph is a graph that has rectangular bars with different lengths representing what they stand for. They are used to compare categorical data.
line graph.
There's a bar graph, pie graph, and a line graph. All represent amounts of change or amounts of a substance. Hope this helped
Bar.?
A Bar Graph
Bar graph :)
yes
A dot plot
it can show data easy to compare
frequency table
Any graph can be used for such a purpose.
You can retrieve information quickly, unlike a graph. It is also easier to compare, and to find the rate of change.
A double bar graph is a graph that uses pairs of bars to compare and show the relationship between data. However, a double line graph is a grid graph that uses pairs of lines to compare and show the relationship between data.
Pie or sector graph
To compare data from different sources.
