Solution and Explanation
Concept:
In an RCT, subjects are randomly allocated to intervention and control groups, then intervention is applied, followed by observation and outcome assessment.
Step 1: Start with randomization.
Participants are first randomly allocated to groups.
Step 2: Apply intervention.
The intervention or manipulation is then given to the experimental group.
Step 3: Follow and assess.
Participants are followed over time and outcomes are assessed. Thus, the sequence is: \[ \text{Randomization} \rightarrow \text{Manipulation} \rightarrow \text{Follow-up} \rightarrow \text{Assessment} \]
