Question

A group of students were given a test in Mathematics, the test was completed by

various students in the following time (in minutes):

24, 30, 28, 17, 22, 36, 30, 19, 32, 18, 20, 24

Find the mean time and median time taken by the students to complete the test​

Answer 1

Answer:

MODE=25

MEDIAN=24

Time taken by students in min.

24, 30, 28, 17, 22, 36, 30, 19, 32, 18, 20, 24.

Mode

• For finding mode we have to add the digits given,and after that we have to divide it by the no.of digits.

Sum of all digits/No.of digits

24+30+28+17+22+36+30+19+32+18+20+24/12

300/12=25

MEDIAN

• For finding median we have to arrange the digits in ascending order,and the centre digit is called the median.

Arrange in ascending order

17<18<19<20<22<24<24<28<30<30<32<36.

The centre digit is 24 and 24,

so the median is 24.
