How do positive correlations and negative correlations differ?
An example of a positive correlation is: the number of cars on the road and the number of greenhouse gas emissions there are. As one of those rises, so does the other. A negative correlation is when one statistic rises causing the other to drop. Look at a few scatter plots and you will easily be able to see positive and negative correlations
When should you use a scatter graph?
The most common plots are bar charts and scatter/ line plots. Scatter plots as used in the Excel program, have continuous scales on the x and y coordinates. So, if your data is measured on a continuous scale, which includes many physical measurements are (ie: temperature, weights, speed, lengths or heights) then a scatter plot makes sense.
Why do scatter plots of summary statistics show less scatter than those of individual observations?
It's bc extrapolation is invloved
When are scatter plots used?
to show the relationship between 2 sets of data
How are scatter plots useful?
