Question

iv) For the data 5,15,20,25,25, then the mean, median and mode is
A) 18,20,25
B) 20,18,25
C)18,18,25
D) 18,15.25​

Answer 1

Answer:

A

Step-by-step explanation:

a because mean is 18 median 20 mode 25

Answer 2

Mean:

${sum \: of \: all \: observation} \div total \: no \: of \: observatio$

Therefore =(5+15+20+25+25)÷5

=90÷5

=18

Median:

$(n + 1) \div 2$

=(5+1)÷2

=6÷2

=3rd observation

i.e. 20

Mode:

$most \: frequently \: number$

here 25 occurs most frequently, i.e. two times

Mean=18

Median=20

Mode=25

Option A is correct
