Question

what is median, mode and mean with examples plz
incorrect answers........WILL BE REPORTED!!!​

Answer 1

Step-by-step explanation:

MEAN: SUM OF ALL OBSERVATION/NO.OF OBSERVATION

FOR EXAMPLE:

find the mean of first ten whole no.

solution:0+1+2+3+4+5+6+7+8+9/10

MEAN:45/10

4.5 ans:

MEDIAN: in median there is two case

1 case:

if the no.of observation is even the median of observation is (n+1/2)th.

2 case:

if the no. of observation is the mean of (n/2)th and n/2+1)th.

if the no. of observation is odd the example is:

find the median of the following data:28,24,22,18,23,26,17

solution:

first step: arranging data in ascending order:

17,18,22,23,24,26,28

n=7 which is odd

median: value of (7+1/2)thobservation = value of 4th observation.

hence median = 23ans:

if the no.of observation is even the example is:

find the median weight of the 8 students whose weight is (in kg) are as follows: 36,38,42,41,40,35,37,45

here n=8,which is even.

median=mean of(n/2) th and (n/2+1)th observation

median=mean of 4th and 5th observation

median= 38+40/2= 39 kg ans:

MODE:

ex: the scores of 15 students in a mathematics test (out of 50)are as follows:

40,48,36,44,36,42,36,48,36,25,42,36,44,40,36

solution:

firstly collect the data which how many time comes:

25 come 1 time

36 come 6 time

40 come 2 time

42 come 2 time

44 come 2 time

48 come 2 time

the observation 36 has maximum frequency,i.e.6.

mode= 36 ans
