If a test is very easy except for a few very low scores, the distribution is (a) Positively skewed

(b) Negatively skewed

(c) Not skewed at all

(d) Normal

✅ Correct option: (b) Negatively skewed

Explanation:

A negatively skewed distribution occurs when most scores are high and a few scores are extremely low. In such cases, the tail of the distribution extends toward the lower end (left side). In an easy test, most students score well, but a few students perform poorly. These low scores pull the tail of the distribution to the left, resulting in negative skewness. In negatively skewed distributions, the mean is typically lower than the median due to the influence of low outliers.

10 Related PPSC Facts:

Negative skew has tail on left. Most scores are high. Mean < median in negative skew. Easy tests produce negative skew. Positive skew has tail on right. Hard tests cause positive skew. Skewness affects interpretation. Normal distribution has no skew. Skewness affects choice of statistics. Median preferred in skewed data.
