Common Student Errors

  • Students often confuse left and right skew. The direction of the skew is the direction the distribution is being pulled. 

  • When asked to compare distributions, students will often list attributes (shape, center, variability, outliers) for each distribution, but without explicitly comparing. To compare, they should use words like “less than”, “greater than”, or “similar to”. 

  • When students are asked to create a graph like a dotplot or stemplot, they often forget to label axes or they set up inappropriate scales. Also, make sure they include a KEY for a stemplot.

  • When identifying the shape of the distribution for a back to back stemplot, they often switch left and right skewed.
