Question

The distribution of exam scores (ranging from 0 - 100%) where the mean score is 75%, the standard deviation is 12%, and the median is 78% is most likely _________.

Answer 1

Answer:

Right skewed

Step-by-step explanation:

A skewed right distribution by definition is "one in which the tail is on the right side".Or on simple words when we have the following property:

$Mode$

Or equivalently:

$Mean> Median>Mode$

A skewed left distribution by definition is "one in which the tail is on the left side". Or on simple words when we have the following property:

$Mode>Median>Mean$

Or equivalently:

$Mean< Median$

And for this case we can see that $Mean =75> Median =78$

So on this case the best description for this distribution is right skewed.
