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.

When the points on a graph tend to scatter randomly you say they indicate?
No 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.
How do you draw a scatter plot with a negative correlation?
you graph the points going downwards
When the points on a graph tend to scatter randomly we say that they indicate .?
That there is no correlation of the collected data.
What is a purpose of a scatter graph?
By finding a correlation trend by means of line of best fit.
What are the disadvantages of a scatter graph?
A scatter graph may use a positive correlation or negative correlation, to shows points of the graph in either a dipping or climbing line, and is fairly easy to read the data. A zero correlation is when the points are scattered across the graph and this can make seeing the data difficult. It's a bit like "dot to dot" in a children's puzzle book, but without the numbers at the side of the dots!
How do you read a scatter graph?
Scatter-plot shows correlation between two different variables (one on the y-axis, the other on x-axis). If there is linear correlation, the scatter-points form a straight line from zero (origo) to some direction. The more cloud-like distribution the scatter-plot does have, the less those variables in question have correlation or dependence with each other.
What is positive corrolation?
When you have a scatter graph and you want to find the correlation of it, you draw a line from one corner to the other of the grid.Also, if the categories are to do with the same thing, then it's a positive correlation.
What is a scatter graph?
A scatter graph, also known as a coordinate graph, a coordinate plot, or a scatter plot, is a graph with coordinates.
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 is the use of scatter graph?
A scatter diagram or scatter graph is used to plot two sets of data to see whether a connection or correlation can be established between them. It is a particularly useful form of graph to use when analysing social science data where you are trying to prove a hypothesis such as 'older people sustain more fractures' or 'the more hours homework a child does the better his/her SATs results will be'.
