Least-squares regression: Checking out two-variable quantitative dataAnalyzing departures from linearity: Exploring two-variable quantitative data
Qualitative data can crank out numerical sample statistics. During the automobile case in point, As an example, we might have an interest inside the proportion of all cars which might be a lot less than six a long time outdated. Inside our identical sample of (two hundred) automobiles we could Notice for every auto whether it is below six decades previous or not, which can be a qualitative measurement.
