Question

following are the observation of throwing a dice 15 times. 5,3,4,1,6,2,2,4,3,2,1,5,1,6,2,​

Answer 1

METHOD 1.

mean = 5+3+4+1+6+2+2+4+3+2+1+5+1+6+2/15

= 8+5+8+6+5+6+7+2/15

= 13+14+11+9/15

= 27+20/15

= 47/15

mode = 2

median = 1,1,1,2,2,2,2,3,3,4,4,5,5,6,6

median = 3

METHOD 2.

rearranging given data

1,1,1,2,2,2,2,3,3,4,4,5,5,6,6

mean =1+1+1+2+2+2+2+3+3+4+4+5+5+6+6/15

=3.13

median =8th term=3

mode=2
