Heights of Black Cherry Trees Frequency ОТ 8 60 65 70 75 80 85 90 Height (feet) Do not worry about the difference between class limits and class boundaries for this example. Just uses classes 60- 65, 65-70, 70-75 etc. 1. Construct a grouped frequency distribution for this data including relative, cumulative, and relative cumulative frequency. 2. Draw a frequency polygon for the data. 3. Draw an ogive for the data. Be sure to label the axis and use appropriate scales. If done using paper and pencil please use a ruler to be accurate.
