Observation and pseudo-experimentation

Date of publication: November 1, 1977

Author: Alain Zwilling


The present paper attempts to illustrate one of the ways data collection may move along: making use of observation and quasi-experimental procedures. This way means improving the approach, by collecting data in strictly defined conditions of the independent variables bearing on the question researched, and by finding hard measures. The present paper intends to illustrate: 1. That all too often the research of validity is not a part of data collection, because data collection is biased towards verbal data. 2. That behavioural data obtained by observation and pseudo- experimentation increase validity. 3. That collecting data by means of observation or pseudo- experimentation may need skill and creativity, but not necessarily large sums of money, therefore increasing value for money at the results level.
