Question

what is mean and median​

Answer 1

The "mean" is the "average" you're used to, where you add up all the numbers and then divide by the number of numbers.

The "median" is the "middle" value in the list of numbers. To find the median, your numbers have to be listed in numerical order from smallest to largest, so you may have to rewrite your list before you can find the median. 

Answer 2

Answer:

Step-by-step explanation:

Mean= sum of all observations / Total number of observations

Eg. Numbers = 6,9,8,7,4,3,2

* Use formula : 6+9+8+7+4+3+2 / 7

Ans = 39 / 7

Median:

Median has two formulas

Odd= (n+1 / 2)

Even =(n / 2 +1 )

Eg :nos 1,2,3,4,5,6

Total numbers = 6 , so n = 6

* Use formula

n = 6 , 6 is a even number

n/2 +1 = 6/2 +1 =6/2 = 3

3+1=4.

So, the answer is 3and 4

Odd:

n+1 /2 = 6+1 /2 = 7/2 =3.5

So, the answer is 3.5

Even = 3,4

Odd = 3.5
