To find the median length of a name from a bar graph, we must add up the number of names. Doing so gives us <math>7 + 3 + 1 + 4 + 4 = 19</math>. Thus the index of the median length would be the 10th name. Since there are <math>7</math> names with length <math>3</math>, and <math>3</math> names with length <math>4</math>, the <math>10</math>th name would have <math>4</math> letters. Thus our answer is <math>\boxed{\textbf{(B)}\ 4}</math>. | To find the median length of a name from a bar graph, we must add up the number of names.

The following bar graph represents the length (in letters) of the names of 19 people. What is the median length of these names?
Solutions
Solution 1
We first notice that the median name will be the name. The name is .
Solution 2
To find the median length of a name from a bar graph, we must add up the number of names. Doing so gives us . Thus the index of the median length would be the 10th name. Since there are names with length , and names with length , the th name would have letters. Thus our answer is .
