Scatter plots (also called scatter charts, scattergrams, and scatter diagrams) are used to plot variables on a chart to observe the associations or relationships between them. Correlations indicate relationships between variables. If you have a correlation coefficient of 1, all of the rankings for each variable match up for every data pair. a. A correlation coefficient by itself couldnt pick up on this relationship, but a scatterplot could. And in a field like technology, the correlation between variables might need to be much higher in some cases to be considered strong. For example, if a company creates a self-driving car and the correlation between the cars turning decisions and the probability of getting in a wreck is r = 0.95, this is likely too low for the car to be considered safe since the result of making the wrong decision can be fatal. Visually inspect your plot for a pattern and decide whether there is a linear or non-linear pattern between variables. When one variable changes, the other variables change in the same direction. 10. A correlation coefficient is a single number that describes the strength and direction of the relationship between your variables. In summary: As a rule of thumb, a correlation greater than 0.75 is considered to be a "strong" correlation between two variables. If we multiply X by a positive number, and multiply Y by another positive number, then the correlation will change. Correlational studies are an example of exploratory research.
