ab: Summary: The study examined first-year engineering studentsâ€™ responses to
a statistics task that asked them to generate a procedure for
quantifying variability in a data set from an engineering context.
Teams used technological tools to perform computations, and their final
product was a ranking procedure. The students could use any statistical
measures, and they needed to explain their ranking procedure in detail.
The responses were first categorized by the statistical measures used.
The responses were categorized using a cyclic model development
perspective moving from primitive to more sophisticated responses. The
modeling cycle framework provided a developmental view of studentsâ€™
responses and use of statistics. The study raised questions related to
the measurement of variability, the application of statistics, and the
process teams go through when designing an analysis procedure.
