Answers
SOLUTION
TO FILL IN THE BLANK
In a continuous frequency distribution class mark of a class is 55 and upper limit is 57, then its lower limit is ______
CONCEPT TO BE IMPLEMENTED
Class Mark :
For any grouped frequency table with class intervals, the middle value of the class limits or the class boundaries of any class is called class mark of the class
EVALUATION
Let lower limit = x
Thus we get
Upper limit = 57
Lower limit = x
Class mark of a class = 55
So by the given condition
FINAL ANSWER
In a continuous frequency distribution class mark of a class is 55 and upper limit is 57, then its lower limit is 53
