Question: Which of the following is an example of inferential statistics?

Option 1: Creating a frequency table. This is a descriptive technique that summarizes the data you have collected, showing how often each category occurs. It does not attempt to make conclusions beyond the observed data.

Option 2: Predicting the election outcome based on poll data. This involves using sample information to make inferences or generalizations about a larger population, which is the core idea of inferential statistics. It goes beyond the data at hand to estimate unknown quantities.

Option 3: Finding the average height of students in a classroom. This is a descriptive statistic because it summarizes the observed data from that classroom without making broader generalizations.

Option 4: Calculating the percentage of survey respondents who prefer a specific product. This is also descriptive, as it reports a proportion from the collected sample without extending the inference to a larger population.

In summary, inferential statistics are about drawing conclusions or making predictions about a population from a sample, whereas the other options describe summarizing or reporting traits of the observed data alone.
