Focus groups can be utilized in the following situations:
• Focus groups help to understand the taste and preference of customers. Hence, it helps to study the consumer behavior regarding a particular product or service.
• It helps to conduct a research for large number of variables.
• Helps to predict the performance of a new product.
• Focus groups provide fast and unbiased results.
Focus groups can't be utilized for the following situations:
• When major decisions of marketing depend on the outcome of a research work, focus groups should not be referred. Quantitative research should be preferred in this case.

Answer:
Two forms of validity used to assess an experiment are internal and external.
Internal validity:
Internal validity can occur when there is a cause-effect relationship exists between the variables to be studied. Therefore, it can be said that Internal Validity exists for dependent variables.
External validity:
External validity exists when the relationship experimental between the independent and dependent variables during the experiment is normal to the real world.
Laboratory experiments are example of internal validity. In these experiments the variables are dependent to each other and there exists a cause-effect relationship. In these experiments each and every variable is controlled and can be manipulated as per the requirement.
Field experiments are those in which the variables are manipulated are independent. The factors are out of control as the an effect is not necessarily the result of one or more known variables.Therefore these variables can not be manipulated.
