Answer 1

Answer:

Formula for finding Median of Grouped Data

_

X= l + h/2 ( n/2- c )

Step-by-step explanation:

• firstly we can derived class boundary due to class limit.
• secondly we can derived commutative frequency due to frequency which we have already given.
• c.limit / frequency / c.boundary / class limit we draw four columns .
• In formula L is actually a lower class boundary. And h is the mid point of lower and upper class boundary.

plz wait i can provide u a proper answer on register.
