Inferential statistics are used to do what?

• A. Generalize from a sample to a population
• B. Describe characteristics of a sample
• C. Compute only descriptives
• D. Prove causation

Answer: (A)

Inferential statistics are used to generalize from a sample to a population. When you can’t study everyone, you collect data from a sample and use probability to draw conclusions about population parameters, like the average or the proportion of a trait. This approach also provides estimates of uncertainty, such as confidence intervals and p-values, so you can say how likely it is that your finding reflects the population rather than random variation. This is different from simply describing the sample, which is descriptive statistics. It also isn’t about proving causation; establishing causal relationships requires appropriate research design and controls to rule out confounding factors.
