Final answer:
Descriptive statistics summarizes data from a sample without making inferences, while inferential statistics makes predictions about a population based on a sample. The statement about 50% of the students surveyed spending two hours online is descriptive statistics.
Step-by-step explanation:
The difference between inferential statistics and descriptive statistics lies in their purposes and methods. Descriptive statistics is used to summarize and describe the features of a dataset, providing simple summaries about the sample. Inferential statistics, on the other hand, involves making predictions or inferences about a population based on a sample of data from that population.
In the survey about internet usage among 200 students, the statement "50% of the students surveyed spend at least two hours online each day" is an example of descriptive statistics because it describes the actual findings of the survey without making predictions or inferences about the larger population.
