Designing an Investigation

that permits a precise replication of the study. Several parts of this chapter apply mainly to a quantitative thesis, but may be appropriate to a non-quantitative thesis as well.

1) Design an Investigation. Explain how the study is designed to investigate each question or hypothesis. If appropriate, identify all variables and how they are manipulated.

2) Population and/or Sample. Describe the principal characteristics of the population selected. If a random sample is used, describe the general population from which the sample was selected and the sampling procedure used.

3) Treatment. Describe the exact sequence followed to collect and tabulate the data. Describe the instrument(s) used to collect the data and establish the validity of the instrument(s) via studies by other researchers.
