Scatter Plots

Scatter Plot

Many situations require the investigating whether a relationship exists between two or more variables. A Scatter Plot is a diagram showing whether two variables are correlated or related to each other. It shows patterns in the relationship that cannot be seen by just looking at the data. It is often used as a first step in analyzing and communicating the correlation between pairs of variables before conducting advanced statistical analyses. It works with both continuous and count data.


Paired Comparison

Paired Comparison Analysis

Paired Comparison Analysis is an activity for evaluating a small range of options by comparing them against each other. It is a useful and easy technique for rating and ranking alternatives where the evaluation criteria are subjective by nature. This is practically helpful when priorities are not clear enough, when alternatives are completely different from one another, or when there is little objective data to base our decision on.
