relative frequency and cumulative frequency of Since class width should be a whole number, we round up to 12. Step 2: Create the Frequency Table We will create a frequency table with class limits, class boundaries, midpoints, frequencies, relative frequencies, and cumulative frequencies. Class Limits Starting from the minimum value (1), and using a class width of 12: 1 to 12 13 to 24 25 to 36 37 to 48 49 to 60 Class Boundaries Class boundaries are used to avoid gaps between classes. They are typically 0.5 less than the lower limit and 0.5 more than the upper limit of each class: 0.5 to 12.5 12.5 to 24.5 24.5 to 36.5 36.5 to 48.5 48.5 to 60.5 Midpoints Midpoints are the average of the upper and lower class limits: (1 + 12) / 2 = 6.5 (13 + 24) / 2 = 18.5 (25 + 36) / 2 = 30.5 (37 + 48) / 2 = 42.5 (49 + 60) / 2 = 54.5 Frequencies Count how many data points fall into each class: 1 to 12: 12 data points 13 to 24: 9 data points 25 to 36: 7 data points 37 to 48: 10 data points 49 to 60: 12
