Question

whats the median number of points & sort the data from least to greatest

Answer 1

$\begin{gathered} 4,5,5,8,8,8,9,12,13 \\ \operatorname{median}\colon8 \end{gathered}$

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

$4,5,5,8,8,8,9,12,13$

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

$\begin{gathered} 4,5,5,8,8,8,9,12,13=9\text{ numbers} \\ \end{gathered}$

weI get an odd number, divide by 2 and round up to get the position of the median number

$\begin{gathered} \frac{9}{2}=4.5 \\ \text{rounded up} \\ 4.5=5 \end{gathered}$

so, the median is the number in poition (5)

$4,5,5,8,(8),8,9,12,13$$\operatorname{median}\colon8$

i hope this helps you.
