Question

the runs scored by two teams A and b on the first 60 balls in cricket match are given below represent the data of both the teams on the same graph by frequency polygons ​

Answer 1

Frequency polygon attached

Step-by-step explanation:

Number of balls Team A Team B

1 − 6                        2                 5

7 − 12                      1                    6

13 − 18                    8                    2

19 − 24                    9                    10

25 − 30                   4                    5

31 − 36                    5                    6

37 − 42                    6                    3

43 − 48                    10                    4

49 − 54                    6                    8

55 − 60                    2                    10

7 - 6 = 1

gap = 1

1 - 6  becomes  0.5 - 6.5

7 - 12 beomes   6.5 - 12.5

and so on

middle = (0.5 + 6.5)/2 = 3.5  

(6.5 + 12.5)/2  = 9.5

and so on

frequency polygon

A frequency polygon is another type of frequency distribution graph. In a frequency polygon, the number of observations is marked with a single point at the midpoint of an interval. A straight line then connects each set of points.
