scatter plot
A line graph.
line graph
Visually as with too much data, the figures become meaningless. Graph it.
bar graph
A bar graph would be best to show a change in data that is not continuous, as it allows for discrete categories to be visually compared easily. The gaps between bars help to emphasize that the data points are distinct and not continuous.
yes
A broken line graph shows information by plotting points of information on the graph and are connected with a line. This is used to show continuous data.
line graph
A line graph is not a good way to represent the data as the number of CDs is a continuous variable, but the artists are a discrete, categoric variable. A line graph should be used when both variables are continuous. A bar chart or bar graph should be used when one variable is continuous and one is discrete.
scatter plot
A broken line on a graph typically represents a discontinuity or missing data points. It can also indicate that the data points may not be continuous or that there is a gap in the data being presented.
It can be, but not necessarily. If I had the heights (continuous variable) of a class of students I might use a histogram. Conversely, if I had the number of cars (discrete variable) driving by every minute, I would use a line graph. It all depends on which kind of graph conveys the information to your audience in the best way.
A bar graph consists of columns of varying height to show data - looking like 'steps' across the page. A line graph uses a continuous line which changes direction with each piece of data.
