I'd choose the survey method for research. It's useful for studying human development as it can cover areas like cognitive, social, and emotional growth. The advantages are that it can reach many people, it's easy to do, and the data can be statistically analyzed. The downsides are that people might answer to look good (social desirability bias), the data is based on what people say about themselves, and if the sample isn't random, some people might not respond (non-response bias). Explanation: The survey method involves asking a group of people specific questions. It's a good way to study human development because you can ask about different growth stages. For instance, you can ask about how people solve problems (cognitive development), how they interact with others (social development), and how they control their emotions (emotional development). The benefits of surveys are that they can reach a lot of people, which makes the results more applicable to a larger group. They're also easy to carry out, and you can use statistics to find patterns and connections in the data. The downsides of surveys are that people might answer in a way that makes them look good, which can skew the results. Also, because the data is based on what people say about themselves, it might not always be accurate. Lastly, if the people you're surveying aren't chosen randomly, some people might not respond, which can also skew the results. rewrite another example
