There are a lot of different types of graphs so it is inevitable that I will miss some but here are the main ones:
Bar / column chart - use if your data is in groups - either categoric (fits into unordered categories such as colour) or split into groups (e.g. 0-10, 10-20, etc.).
Histogram - extension to the bar chart - use if the data is split into groups that are unequal (e.g. 0-10, 10-15, 15-30, etc.).
Scatter chart - use if all of the data is continuous (i.e. can be any value within a range (e.g. time/temperature).
Line graph - extension to the scatter chart - has a line of best fit - use if the two sets of data on the x and y axis are related.
Pie chart - use if you want to show fractions of the data (e.g. that over half of people have one car but that only a quarter have two) - the data must be categoric (described above).
line graph
to represent and compare datas to it.
No, it is not an appropriate graph.
when you can't find any other peice of graph paper
A pie graph is useful for showing percentages. It is great for showing percentages in a survey.
For any data that can be best expressed as percentages of a whole, a pie chart or pie graph is appropriate.
line graph
You select an appropriate scale.
When determining the appropriate name for a graph, consider the data being represented and choose a title that accurately describes the information displayed in the graph.
Meaning of "Is the Scope of the graph appropriate? "
The answer depends on what the data are: if you want to compare times before and after practise then a scatter graph may be appropriate. If it is the times in a single experiment then a bar chart for frequencies in time intervals or a histogram may be appropriate.
A concrete graph is a graph that records, organizes, and displays data using objects on a mat with appropriate labels.
