Question

the dot plot below represents the number of letters in the last names of some students in a class.
name length
what was the median name length?
answer attempt 1 out of 2
letters

Explanation:

Step1: Count the total number of data points

Count the dots: \(1 + 3+1 + 1+1 = 7\) data points.

Step2: Find the median position

For \(n = 7\) (odd number), the median is the \(\frac{n + 1}{2}=\frac{7+ 1}{2}=4^{th}\) ordered - value.

Step3: List the data in order

The data values (number of letters) in order: \(4,6,6,6,7,9,10\)
The \(4^{th}\) value is \(6\)

Answer:

\(6\)
