Normal Distribution
I understand that a continuity correction should be used when using a continuous distribution to approximate a discrete distribution or situation.
My textbook says I should also use a continuity correction if applying a normal distribution to rounded continuous data.
However all continuous data must be rounded before it is recorded, so this would mean a continuity correction would always be needed. Is this correct?
