![\begin{gathered} 4,5,5,8,8,8,9,12,13 \\ \operatorname{median}\colon8 \end{gathered}]()
Step-by-step explanation
Step 1
graph the point is a numerical line
now, to order from the least fo greatest, write the numbers from left to rigth
![4,5,5,8,8,8,9,12,13](https://img.qammunity.org/2023/formulas/mathematics/college/vdp5b3vutpyl2wr0fo15r2sfkbwxvxg9og.png)
Step 2
now, The median is the middle number in a sorted, ascending or descending, list of numbers and can be more descriptive of that data set than the average.
so
Count how many numbers you have
![\begin{gathered} 4,5,5,8,8,8,9,12,13=9\text{ numbers} \\ \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/zts94r7awgw26ypmck26h19nn3mgl67kp6.png)
weI get an odd number, divide by 2 and round up to get the position of the median number
![\begin{gathered} (9)/(2)=4.5 \\ \text{rounded up} \\ 4.5=5 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/pa8n759k42dbn9atn2e3j23n51nika1b5b.png)
so, the median is the number in poition (5)
![4,5,5,8,(8),8,9,12,13](https://img.qammunity.org/2023/formulas/mathematics/college/vpgmc5fnvut9nvm305877l72uie522jk5s.png)
![\operatorname{median}\colon8]()
i hope this helps you.
