Which concept is the likelihood of an outcome occurring?

• A. Probability
• B. Sampling Error
• C. Distribution of Sample Means
• D. Central Limit Theorem

Answer: (A)

Probability is the measure of how likely an outcome is to occur. It assigns a number between 0 and 1 (or 0% to 100%) to indicate how probable a specific event is. The phrase “likelihood of an outcome occurring” directly refers to this idea of probability, which tells you how often you would expect that outcome in repeated trials under the same conditions. For example, the probability of rolling a 4 on a fair die is 1/6. The other concepts describe different things: sampling error is about how a sample’s result may differ from the true population value due to random selection; the distribution of sample means concerns how the averages from many samples would be spread; and the central limit theorem explains that, with enough data, the distribution of those sample means tends to be normal. These relate to sampling and distribution properties rather than the likelihood of a single outcome.
