Final answer:
To understand how people are responding to lockdown orders, a survey study or a cross-sectional study would be most effective; a survey study collects ongoing opinions, while a cross-sectional study assesses the situation at a single point in time.
Step-by-step explanation:
To gain a better understanding of how a group of people are responding to recent lockdown orders, the type of study you might run is a survey study. This involves collecting data through questionnaires from a representative sample of the population to understand behaviors, attitudes, and opinions regarding the lockdown. Alternatively, a cross-sectional study could be used to gather data at a single point in time to assess the prevalence of certain opinions or behaviors in response to the lockdown. A longitudinal research could be considered too, but it involves following a group of research participants over an extended period, which may not be ideal if immediate insights are needed.
Case studies provide an in-depth analysis of individual cases, which might not be representative of the group's response as a whole. Case-control studies are retrospective and compare subjects with and without certain traits, which might not be suitable for this scenario where the response to a current event is being assessed.
