Question

identify the distribution as symmetric, left - skewed, or right - skewed. exam scores for an exam in which most students did very well but a few students failed a. left - skewed b. symmetric c. right - skewed

Explanation:

In a left - skewed distribution, the tail is on the left side. When most students do very well (high scores) and a few students fail (low scores), the lower scores (failures) pull the tail of the distribution to the left. A symmetric distribution has no skew. A right - skewed distribution has its tail on the right (would be the case if most students failed and a few did well).

Answer:

A. Left - skewed
