thank this help but how to put class interval 50 - 55 instead of putting midpoint 52 in the histogram?

Thank you very much.. I noticed when i used less than 4 decimal places, i could not get the relative freq. to equal 1.0 ... does this mean that the more decimal places you use, the more accurate the histogram would be? So we should always use as many decimal places as possible?
