Explanation:
Given
See attachment for dot plot
Required
The center of data
This implies that, we calculate the median
From the attached plot,
--- number of observation
So, the median is:
![Median = (n + 1)/(2)](https://img.qammunity.org/2022/formulas/mathematics/high-school/jdb0k1tbid7rpd4fdemn0m88y13to7g96j.png)
![Median = (13 + 1)/(2)](https://img.qammunity.org/2022/formulas/mathematics/high-school/jhn7hxlwyqfwl720x0l5alceefk6n5s3mr.png)
![Median = (14)/(2)](https://img.qammunity.org/2022/formulas/mathematics/high-school/itzm4zliz4d85phswqhhwe3wck6gb0bwpo.png)
![Median = 7th](https://img.qammunity.org/2022/formulas/mathematics/high-school/bfiwumhctgkfsxqwf2weacvaq3blfu7fa6.png)
The median is at the 7th position
At the 7th position, is 13
Hence:
![Median = 13](https://img.qammunity.org/2022/formulas/mathematics/high-school/ozlhp00rawnzft351lsze1qr9qhzfgdtb8.png)
