Measures of Position for Grouped Data

How do we get the lower boundary (LB)?

• By subtracting 0.5 from the lower limit.

• By subtracting 0.5 from the upper limit.

• By adding 0.5 from the lower limit.

• By adding 0.5 from the upper limit.

"n" is obtained by adding all the data in the less than cumulative frequency column.

• True

• False

• Maybe

• The answer must be frequency column

To locate the quartile class for grouped data, we must compute for its class first. What is the formula should we use?
