What type of data does a line graph represent?
Stocks, or anything that would rise or decrease.fd
It would represent continuous data, rather than discrete data. Continuous data would be something like height, which increases by fractional amounts, and since a line can represent any length between 5 and 6 ft. (like 5.25 or 5.379) a line is used to represent height. Number of customers would be discrete data, represented by discontinuous dots, since you can only have whole customers, and not parts of customers. Between 5 and 6 customers, there would be no line, since a line would show that there can be parts of customers between 5 and 6.

Is a bar graph discrete or continuous?
It is both, a bar graph can be for discrete and continuous it depends on how you set out the chart. If it is for discrete data then you have to have a gap between each bar but on a continuous bar graph they are all next to each other WITHOUT any gaps. Also another way to discover if a bar graph is discrete or continuous the dicrete graph bars are labelled individually but on a continuous they are not labelled as such; there is a scale on the bottom axis. Hope this helps who ever needs it :D
