Question

the points scored by a basketball team in a series of matches are as follows 17 , 7 , 10,25, 5,10,18,10,24 find the mean

Answer 1

17+ 7+ 10+ 25+5+10+18+10+24/9 =126/9 =14

Answer 2

the points are 17,7,10,25,5,10,18,10,24.
total no of observations is 9
sum of observations = 17+7+10+25+5+10+18+10+24 = 126
mean = sum of observations by no of observations = 126/9 = 14

so the mean is 14
