got it... in the Q7. we got 9th observation by adding 25 with 87=112... but in Q8. after calculating the avg of last two data it was +4 ... if we add +4 with 34( which is avg. of 7 data) it will be 38... which is more than the avg. of 7 data.... the avg. of last two data must be -4 so it can be within the avg. of 7 data.... may be or may not be I'm correct
Sir in the 5th slide, 2nd we u divide 8 with 2??
