To measure the effectiveness of a management style, a consultant uses one approach with one group of employees and a second approach with another, while only she knows which technique is being investigated. Which procedure is this?

1. Double-blind

2. Tandem sampling

3. Single-blind

4. Correlative method

The correct answer is: Single-blind

The procedure described is a single-blind study, which involves manipulating one variable while keeping participants unaware of certain conditions to prevent bias in their responses. In this scenario, the consultant is aware of which management style is being used with each group of employees, but the employees themselves do not know which management style they are experiencing. This setup allows the consultant to measure the effectiveness of the different management styles without the employees being influenced by their knowledge of the study's focus. In contrast, a double-blind study would involve both the participants and the experimenters being unaware of which treatment is being administered, which is not the case here since the consultant knows the conditions. Tandem sampling relates to collecting multiple samples in a sequence or pair, which doesn't apply to the context of management style effectiveness. The correlative method refers to analyzing the relationship between two variables rather than manipulating variables as is done in this scenario. Thus, the single-blind approach is the most accurate descriptor of the procedure used by the consultant in the situation provided.
