What graphs can you use to measure correlation?
A scatter graph can be used to establish whether or not there is correlation and to get an approximate idea as to its strength. But no graph will actually measure correlation.
What kind diagram is used to graph two-variable data for correlation analysis?
A scatter plot.A scatter plot.A scatter plot.A scatter plot.
When do you use a column scatter graph?
Never. You can use a column graph, or a scatter graph or even a superimposition of the two but there a column scatter graph does not exist.
What graphs can you use to find the strength of correlation between two continuous data sets that isn't a scatter graph?
You cannot. Or rather, you should not. You do not know if the relationship is linear or something else. A scatter graph is the best way to establish the nature of the relationship. For example, the correlation between x and y, when y = x2 between, say, -4 and +4 is zero (because of symmetry). That would lead you to conclude that there was no relationship. You could not be more incorrect!
What is the difference between a line graph and a scatter graph?
A line graph would be what you plot for a function. for example, y = X2. Plotting this will result in a continuous line.A scatter graph will result from measuring a population or an experiment.For example, if you plotted the weight vs height for your class members, you would have a scatter graph.
