Numeric response

Introduction

Questions that involve numbers provide the prototypical examples of generative questions.

Questions that use random numbers:

can be used, and reused, in formative assessments for practice during the period of study or for revision prior to an examination
impede collusion between students in summative assessments

Numeric responses from students can be handled as:

exact integers e.g. 13
floating point numbers within a tolerance range e.g. 3.14159
floating point numbers to a set number of significant figures e.g. pi to 4 significant figures is 3.142
numbers in scientific format e.g. 1.38 × 10^-23
numbers with units e.g. 1.38 × 10^-23 m² kg s^-2 K^-1
