The way we choose to collect data can influence, in many ways, the data that we actually collect.

Consider the situation where you are asked the following question: "when was the last time that you attended a sports event?"

• Think of what might come to the responders' mind. What came to your mind? What about the choice of data types?
• Is it the same to ask how satisfied you are with this class by providing a list of choices (for instance, "not satisfied", "somehow satisfied", "satisfied", "very satisfied"), or providing a Likert scale with 4 points?
• And if you use a Likert scale, can the distance between the points introduce bias in the results?

Think of these and many other situations where data collection might introduce bias in the results. Explain HOW the introduction of bias in the results could happen, WHY, and provide EXAMPLES.
