You should determine which is the appropriate research type and method for each company and justify it. Exploratory research Since there is a need to measure the brand image and since there is not a clear idea of what the exact problem is, exploratory research would be best for Client A. Descriptive research Causal research Here, the Client B wants to determine how sales are affected, what affects them, and when advertisements are most effective. These questions of who, what, where, when, why, and how are best answered by descriptive research.

These are causal relationships, and therefore best investigated by causal research. PS. DO NOT FORGET TO INCLUDE THE METHOD AS WELL
