what is mode,mean,mediun full explanation wrong answer will be reported and delete his all questions and answers
Answers
MODE = the number which comes most of times.
MEAN = remove comma and add all the number after adding divide it.
MEDIAN = first arrange the number as ascending order and the number in between is called the median.
EXAMPLE:
1,3,2,6,2,3,1,3
MODE = 3 Ans because it is coming most of the time. MEAN = 1+3+2+6+2+3+1+3
8
=21 = 2.625 Ans
8
MEDIAN = 1,1,2,2,3,3,3,6 = 2+3 = 2.5 Ans
2. 2
Take another example of median.
3,1,5,6,3,4,5
=1,3,3,4,5,5,6
It is odd number so we had to find the middle number.
= 4 Ans
I hope this will help you
Mode:
Mode is the number that occurs the maximum number of times.
Examples
Ex 1:
1,5,6,7,6,8,9,0
Here mode is 6 since 6 is repeated maximum number of times.(2 times)
Ex 2 :
8,2,5,6,8,6,7,0
Here mode is 8 and 6 because they are repeated maximum number of times(2 times)

Mean:
Mean is the average value of a group of observations in a given data.
Mean formula
Mean = Sum of observations/ no of observations
Examples:
Ex 1 : Find mean of 2,3,5,6
We know that,
Mean = Sum of observations/ no of observations
Mean = 2+3+5+6 / 4 = 16/4 = 4
Therefore, mean is 4
----------------------------------------------------------------------
Median :
Median is the value of the middle observation when data is in ascending order or descending order.
Median formula (when no of observations is odd)
Median = n+1/2
Median formula (when no of observations is even
Median = 1/2 ((n/2 th) + (n/2 + 1 th))
Examples
Ex 1 :
Find median of 10, 10, 13, 10, 14, 11, 9
Ascending order of observations:
9, 10, 10, 10, 11, 13, 14
No of observations = 7
We know that
Median = n+1/2
Median = 7 + 1 / 2 th = 8/ 2 th = 4th
Therefore,median is 4th observation which is 10
Ex 2 :
Find median of 10, 10, 13, 10, 14, 11, 9, 12
Ascending order of observations:
9, 10, 10, 10, 11, 12, 13, 14
No of observations = 8
We know that
Median = 1/2 ((n/2 th) + (n/2 + 1 th))
= 1/2 ((8/2th) + (8/2 + 1 th))
= 1/2 ((4th) + (4 + 1 th))
= 1/2 ((4th) + ( 5th))
= 1/2 (10 + 11)
= 1/2 (21)
= 21/2
= 10.5
Therefore 10.5 is median
