What is the purpose of inferential statistics?

• A. To describe sample data only
• B. To make predictions about a population based on sample data
• C. To summarize data with visuals
• D. To explore personal narratives

Answer: (B)

The purpose of inferential statistics is indeed to make predictions or inferences about a larger population based on observations drawn from a smaller sample. This methodology allows researchers to use sample data to estimate population parameters, test hypotheses, and draw conclusions that extend beyond the immediate data set. Inferential statistics employs various techniques, such as hypothesis testing and confidence intervals, to determine whether observed patterns in the data can be generalized to a broader context. For instance, if a researcher conducts a study involving 100 individuals to infer conclusions about a population of 10,000, inferential statistics allows them to relate findings from that limited sample to the entire population, estimating the likelihood that their observations reflect the truth at the population level. This approach is distinct from descriptive statistics, which is concerned with summarizing and describing the features of the sample data alone, without making broader inferences. Options focused on visual data representation or personal narratives do not pertain to the core objectives of inferential statistics.
