1) sample

2) discrete ; as number are integers

3)

cumulative freq for second class =19

cumulative freq for fourth class =36

4)ascending above:

step 1mean: total/8=-8/8=-1

step 2) median =(n+1)/2 th value =(8+1)/2 =4.5 th value =(-2-2)/2 =-2

step 3)mode: =5 ; unimodel

class freq cumulative freq 0.23-0.31 14 14 0.32-0.4 5 19 0.41-0.49 8 27 0.50-0.58 9 36 0.59-0.67 10 46
