2. The scatterplot – the 2nd technique in correlation analysis Start here on 9/20/16. Creating a Scatterplot. A scatterplot is simply a plot of individual Y values vs. individual X values. Note that values that are being or might be predicted are put on the vertical axis.

An assumption of regression analysis is that residuals are random, independent, and normally distributed. A residual plot can help you spot extreme outliers or departures from linearity. Bivariate scatter plots can also provide helpful diagnostics, but a plot of residuals is the best way to find multivariate outliers.

Regression analysis can be defined as the process of developing a mathematical model that can be used to predict one variable by using another variable or variables. This section first covers the key concepts of two common approaches to data analysis: graphical data analysis and correlation analysis and then introduces the two main types of ...

It will be used to illustrate concepts in correlation and regression. One would expect, from the context of the example, that the variables t50 and t90 ought to be strongly related. Here is output from Minitab showing the value of r: Correlations: t50, t90 . Pearson correlation of t50 and t90 = 0.868. P-Value = 0.000. Regression Analysis: t90 ...

Regression Analysis Vs. Correlation Analysis. Correlation: An analysis which assesses the strength and direction of relationship between X and Y. Regression: An analysis that allows you to predict or explain Y from X. Requires a prior correlation analysis confirming a relationship between X and Y. So correlation analysis is a step on the way to ...
