Finding the Median Height
The median is the middle value in a dataset that has been ordered from least to greatest. To find the median height of the 9 students, we first need to arrange the given heights in ascending order.
Ordering Student Heights
The heights (in cm) are: 155, 160, 145, 149, 150, 147, 152, 144, 148.
Arranging these heights in ascending order:
- 144
- 145
- 147
- 148
- 149
- 150
- 152
- 155
- 160
Calculating the Median Position
There are $n=9$ students. Since $n$ is an odd number, the median is the value at the middle position.
The position of the median is calculated using the formula: $\frac{n+1}{2}$
Position = $\frac{9+1}{2} = \frac{10}{2} = 5$.
This means the median is the 5th value in the ordered list.
Identifying the Median Value
Looking at the ordered list of heights:
144, 145, 147, 148, 149, 150, 152, 155, 160
The 5th value is 149.
Therefore, the median height of the 9 students is 149 cm.
