reSolve: Authentic Problems: Reaction Time
This sequence of four lessons focuses on collecting data and working with decimal numbers in the context of students measuring reaction times. Students formulate and refine an authentic inquiry question related to their own statistical investigation, and plan how to investigate it. They compare and order decimals that represent very fast and precise reaction times. They construct data displays, including dot plots, appropriate for the data, and justify their conclusions. Each lesson is outlined in detail including curriculum links, vocabulary, materials needed, sample answers, discussion points and student resources. This sequence is part of the reSolve: Mathematics by Inquiry special topic 'Authentic Problems'.

Interpret, compare and order numbers with more than 2 decimal places, including numbers greater than one, using place value understanding; represent these on a number line
Plan and conduct statistical investigations by posing questions or identifying a problem and collecting relevant data; choose appropriate displays and interpret the data; communicate findings within the context of the investigation
Acquire, validate and represent data for nominal and ordinal categorical and discrete numerical variables to address a question of interest or purpose using software including spreadsheets; discuss and report on data distributions in terms of highest frequency (mode) and shape, in the context of the data
