a. Surveys and Interviews; Large sets of complex data
b. Surveys and Observations; Extremely large sets of simple data
c. Experiments and Observations; Large sets of complex data
d. Experiments and Interviews; Extremely large sets of simple data

Answer 1

To collect data, methods such as surveys, interviews, observations, and experiments can be used. Data can be classified as qualitative or quantitative. Big data refers to extremely large sets of complex data.

Step-by-step explanation:

To collect data, there are several methods including surveys, interviews, observations, and experiments.

Surveys and interviews involve asking questions to individuals to gather information. This method is suitable for gathering data on people's opinions, experiences, and behaviors.

On the other hand, observations and experiments involve directly observing and recording data. This method is useful for studying natural phenomena and collecting objective data.

When it comes to classifying data, it can be done based on categories. For example, data can be categorized as qualitative (categorical) or quantitative (continuous or discrete).

Big data refers to extremely large sets of complex data. It often requires advanced computational tools and techniques to process, analyze, and extract meaningful insights from the data.
