Answer
Answer:
65
Explanation:
Step1: Write out the data set
The data set from the stem - and - leaf plot is: 45, 50, 52, 58, 62, 68, 72, 78, 81, 95.
Step2: Determine the number of data points
There are $n = 10$ data points.
Step3: Calculate the median position
For a data set with $n$ data points (where $n$ is even), the median is the average of the $\frac{n}{2}$th and $(\frac{n}{2}+ 1)$th ordered data points. Here, $\frac{n}{2}=\frac{10}{2}=5$ and $\frac{n}{2}+1 = 6$.
Step4: Find the median
The 5th value is 62 and the 6th value is 68. The median is $\frac{62 + 68}{2}=\frac{130}{2}=65$.
