Data Handling: Choice of graphs by Xue Qin

Task 1: 

1.Can you identify which is the least appropriate?

Line graph is unsuitable for representing the information 

2.Why do you think it's not appropriate?

 I think it’s inappropriate for representing information as line graph* are used when comparing the level or trend of the same thing (for example: The rainfall per month), while 

*A line graph is a type of chart which displays information as a series of data points connected by straight line segments. It is a basic type of chart common. It is similar to a scatter plot except that the measurement points are ordered  and joined with straight line segments. A line chart is often used to visualize a trend in data over intervals of time – a time series – thus the line is often drawn chronologically. 

3. What makes you think that the other graphs are appropriate? 

Pictograms,bar graphs, pie charts can be used to compare different things (for example: The no. students that read a certain genre of books) as well as represent the different level/ degree of a certain data.
