In this paper, I demonstrate how to assess the heteroskedasticity problems in cross-sectional studies that use linear regression models using my \emph {HeteroskedasticityV3} SPSS macro. I present two illustrative examples inspired from real research. This paper also provides the annotations of the macro outputs. In my classroom demonstrations, students were asked to analyse data sets used in this paper and discuss their regression results with and without implementing robust standard errors. The merits of checking for the presence of heteroskedasticity prior to adjusting robust standard errors were also discussed in class.
