Choosing between surveys, experiments, and observations can be tough for Year 11 math students. Let’s break it down!

1. Picking the Right Method:

   • Students often struggle to find the best way to gather data for their questions. If they choose the wrong method, the data they collect might not be useful. This can affect how solid their findings are.

2. Limited Resources:

   • Doing experiments might need special tools or places that students can’t easily get to. Surveys can have low response rates, meaning not many people answer them. Observations can be influenced by what the observer thinks. Each method has its own challenges that can make collecting data hard.

3. Understanding the Data:

   • Different methods give different kinds of data, which can make it confusing to analyze. For example, data from experiments requires math skills, while data from observations needs looking for common themes. This mix can be a lot for students to handle.

4. Avoiding Bias:

   • It's really important for students to collect data without bias, but that’s not easy. Surveys might have issues where only certain types of people choose to respond. Experiments need to be careful about outside factors that can change the results.

To help with these challenges, teachers should guide students on how to choose the right methods. They can also give resources for experiments and teach students how to collect data fairly. By focusing on these areas, students can get better at their research and handling data.
