1.	The class mark of a class interval isA) upper boundary + lower boundaryB) upper boundary – lower boundaryC) \(\frac{upper\,boundary\,+\,lower\,boundary}{2}\)D) \(\frac{upper\,boundary\,-\,lower\,boundary}{2}\)
Answer» Correct option is: C) \(\frac {Upper \, boundary + Lower \, boundary}2 \) Class mark = \(\frac {Upper \, boundary + Lower \, boundary}2 = \frac {U+L}2\) Correct option is: C) \(\frac{upper\,boundary\,+\,lower\,boundary}{2}\)

The class mark of a class interval isA) upper boundary + lower boundaryB) upper boundary – lower boundaryC) \(\frac{upper\,boundary\,+\,lower\,boundary}{2}\)D) \(\frac{upper\,boundary\,-\,lower\,boundary}{2}\)

Answer»

Correct option is: C) \(\frac {Upper \, boundary + Lower \, boundary}2 \)

Class mark = \(\frac {Upper \, boundary + Lower \, boundary}2 = \frac {U+L}2\)

Correct option is: C) \(\frac{upper\,boundary\,+\,lower\,boundary}{2}\)
