Question

1. what is the median for the data in the dot plot?

Explanation:

Step1: Count the number of data points

There are \(1 + 2+1 + 1+2=7\) data points.

Step2: Find the position of the median

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

Step3: Order the data and find the median

The ordered data set is \(5,7,7,8,9,10,10\). The \(4^{th}\) value is \(8\).

Answer:

\(8\)
