Question

the two consecutive class mark of a dustrubution are 52 and 57 .find the class limits of the two tervals

Answer 1

class marks are 52 , 57

Therefore class size = 57-52=5

Now we know lower and upper class limits for 52 are

lower limit=52 - 5/2=49.5 

upper limit=52+5/2= 54.5

Now for 57

lower limit= 57-5/2= 54.5

upper limit = 57+5/2= 59.5

Therefore we obtain

CLASS MARKS 》CLASS LIMITS
52. 》49.5-54.5
57. 》54.5-59.5
