When a score distribution has a long tail extending toward the lower values (left), the distribution is described as:
Answer and explanation
Correct answer: A. Negatively skewed (left-skewed)
- Step 1: The direction of skewness refers to the direction in which the thin tail points. Step 2. A tail pointing towards lower scores indicates negative (left) skewness, where mean < median. Answer: Negatively skewed (left-skewed). Why not the others: Positively skewed has the tail pointing towards high scores; bimodal has two distinct peaks; uniform has equal frequencies.
