Question

Find the mean ,mode meridian and range of data 11,12,13,12,13,14,12,18,21,2,15​

Answer 1

Answer:

Step-by-step explanation:

mean=sum of all element/total number of elment present

       143/11=13

mode=highest frequency(joh sbse zyda repeate kar rha ho)=12

dont know about meridian and range

Answer 2

Given,

No. of observations(11)=11,12,13,12,13,14,12,18,21,2,15

Mean=11+12+13+12+13+14+12+18+21+2+15

11

=13

Mode=12(3times)

Median(In ascending order)=2,11,12,12,12,13,13,14,15,18,21=13

Range=Highest no.-Lowest no.=21-2=19

Therefore,Mean=13;Mode=12;Median=13;Range=19
