Procedure :

1. Select dicot plant body and identify ten leaves that will be measure


2. Make sure that the leaf is always the third leaf in a woe considering the lowermost leaf as the first


3. Measure (millimeter (mm) the length and broadest width of the leaf


4. Record the measured values on the activity sheet


5. Obtain the measurements made


6. Compute for sample mean (x), sample variance and sample standard deviation


7. Plot frequency against the measure value to prepare histograms
