Question

19) Find the mean , median and mode of 18, 26, 33, 42 , 18 ,4,9, 18
17 and 26.​

Answer 1

Answer:

ex= 18+26+33+42+18+4+9+18+17+26

= 211

number (n) = 10

we know,

mean = ex/ n

= 211/10

= 21.1

again,

median = n+ 1 /2

= 10+1/2

= 11/2

5.5

now,

Here, 18 has the highest frequency. so mode is 18.
