Teachers’ Use of Informal Conceptions of Variability to Make Sense of Representativeness of Samples
Page: 1497

This paper contains data on how in-service middle school teachers and a community college faculty member reasoned through two statistical tasks. The researcher presents his analysis of the data through the lens of how teachers reasoned about variability as they worked through the two statistical tasks.
