Question

Write class limit and class size of the following:
47 52 57 62 67 72 77

Answer 1

Answer:

class size = difference between two consecutive class Mark

therefore it is 5

lower limit= class Mark- class size/2 = 44.5

upper limit= class Mark+ class size/2 = 49.5

therefore limits are--

44.5 - 49.5

49.5-54.5

54.5-59.5

59.5-64.5

64.5-69.5

69.5-74.5
