Question

the dot plot shows the number of words students spelled correctly on a pre - test. which statement best describes the shape of the graph? the graph is skewed right. the graph is nearly symmetrical. the graph is skewed left. the graph is perfectly symmetrical. spelling pre - test number of correct words

Explanation:

A perfectly symmetrical graph has identical halves. A nearly symmetrical graph is close but not exact. A skewed - right graph has a longer tail on the right; a skewed - left graph has a longer tail on the left. Looking at the dot - plot, it is not perfectly symmetrical (due to minor differences in dot distribution), but it is close to being symmetrical.

Answer:

The graph is nearly symmetrical.
