Aimed at those new to the area, and those who have collected time-series data before, this book intends to facilitate the interpretation of observations of behaviour, physiology, mood, perceptual threshold, social indicator variables and other responses. It focuses on practical applications and requires much less mathematical background than many other texts. Using real data sets and the available software (SPSS for Windows), the book employs examples to clarify key concepts. Topics covered include research design issues, preliminary data screening, identification and description of cycles, summary of results across time series, and assessment of relations between time series. Also considered are theoretical questions, problems of interpretation and potential sources of artefact.
