Further Investigations of Reaction Times 
The investigation section of this site deals with the development and increasing sophistication of statistical investigations. It is based around the four aspects of posing questions, collecting data, displaying data and discussing results. These four are closely linked as what data is collected can dictate the way that it is displayed and the conclusions that can be reached from the investigation. On the other hand, if some restrictions have been placed on the means of display, only certain types of data collection may be relevant. A number of these statistics investigations involve the use of computer spreadsheets. These units are marked with *.
