Question

Ill give brainliest to the correct and best explained answer :)) ​

Answer 1

Solution:

Step-1: Re-arrange the following data from biggest to smallest.

• 30, 10, 40, 20, 60, 50, 80, 70, 90
• => 90, 80, 70, 60, 50, 40, 30, 20, 10

Step-2: Refer to the following:

    1. If there is an even number of digits, you will use the formula:

• (Total number of digits)/2

    2. If there is an odd number of digits, you will use the formula:

• (Total number of digits + 1)/2

Step-3: Find the median:

If we count the number of digits in the data, we can say that nine numbers are in this data. Thus, we will use the formula "(Total number of digits + 1)/2"

• => (Total number of digits + 1)/2 term
• => (9 + 1)/2 term
• => 10/2 term
• => 5th term

The fifth term of the group is the median.

Step-4: Review the "biggest to smallest" data.

• 90, 80, 70, 60, 50, 40, 30, 20, 10

Since 50 is the 5th term, the median is 50.

Answer 2

Answer:

Step-by-step explanation:

To find the median, arrange the data in ascending order

10,20,30,40,50,60,70,80,90

Number of data = 9 . It is a odd number

So, median will be the (n+1)/2 th term

$\left(\dfrac{9+1}{2} \right)^{th \ term} = (\dfrac{10}{2})^{th \ term} = 5^{th \ term}$

Median =  50
