The methods of collection for primary data include:

1. Focus groups: This method involves gathering a group of people who are representative of the users or customers you're interested in. You then facilitate a discussion around the topic you're researching. This can provide valuable insights into user behavior, preferences, and opinions.

2. Customer comments: This involves collecting feedback directly from customers. This can be done through various channels such as surveys, feedback forms, social media, or direct communication. This method can provide direct insights into customer satisfaction and areas for improvement.

3. The Census of Retail Trade: This is a specific example of a survey method. Surveys are a common method for collecting primary data. They can be conducted in person, over the phone, or online. They involve asking a series of questions to a sample of individuals from your target population.

4. Observation: This involves directly observing and recording behavior or other phenomena as they occur in a natural setting. This can provide very accurate data, but it can also be time-consuming and difficult to carry out on a large scale.

So, all of the options listed are methods of collection for primary data.
