Final answer:
To understand the increase in break-ins in Lakeside during 2021, the researcher should conduct a descriptive study to gather and analyze data on the characteristics and patterns of the break-ins.
Step-by-step explanation:
If a researcher wanted to know why there was a noticeable increase in the number of break-ins in the town of Lakeside during 2021, the most appropriate design would be a descriptive study. Descriptive studies are used to describe characteristics of a population or phenomenon. In the case of examining the increase in break-ins, the researcher would gather data about the break-ins that occurred, including when and where they happened, the characteristics of the properties targeted, and any patterns or trends that emerge from the data. This type of study could also involve collecting qualitative data from interviews with local authorities, victims, or even the perpetrators, if possible. By collecting and analyzing this data, the researcher can form a picture of what might be contributing to the increase in break-ins.
In contrast, correlational studies primarily look for a relationship between two or more variables, but they do not determine causation. Experimental studies involve manipulation of variables and control conditions, which is not feasible in studying crimes that have already occurred. Case studies focus in depth on a single case or instance, which would not provide enough information in this scenario where a broader understanding is needed.
