b. Social media posts

d. Clickstream data
e. 2 of the above are examples

Answer 1

Social media posts and clickstream data are examples of unstructured data because they do not adhere to a predefined data model and vary widely in format and content.

Step-by-step explanation:

When evaluating unstructured data, we look for data that does not follow a predefined model or is not organized in a predefined manner. B social media posts are an example of unstructured data because they come in various forms like text, images, or videos and do not follow a strict schema. Similarly, D clickstream data is also considered unstructured data as it consists of user navigation pathways on websites and can vary widely in format and content. Thus, the correct answer here is E 2 of the above are examples referring to both social media posts and clickstream data.

Data can take various forms, such as quantitative discrete, which are countable items like the number of tickets sold to a concert, or quantitative continuous, representing measurable quantities that can take any value, like time or distance.
