Question

the marks obtained in a test conducted for 5 students are 15,22,12,11 and 10 . find the mean and median​

Answer 1

Answer:

MEDIAN=12

MEAN=14

Step-by-step explanation:

Ascending Order of marks=10,11,12,15,22

MEDIAN=MIDDLE MOST OBSERVATION

10 , 11 , 12 , 15 ,22

Here 12 is in the middle.

Therefore, median=12

MEAN=SUM OF ALL OBS.÷NO.OF OBS.

=10+11+12+15+22/5

=70/5

=14

Here the answer is 14

Therefore, mean = 14

Answer 2

Step-by-step explanation:

1)mean = 15+12+22+11+10

5

= 70/5

mean =14

2) median

arranging the digits in ascending order

10,11,12,15,22

( n+1 )th =( 5+1)th

2. 2

= (6/2)th

= 3

This means that 3rd no. is the median

hence, median = 12
