Frequency Distribution Table

• HS – LS = Range
• Range + 1 = Potential Score
• R/(1+3.322logN) = Class Size
• Potential Score divided by Class Size = Class Interval
• Frequency = number of all collected data
• LL -0.5 / UL +0.5 = Class Boundary
• (UL+LL) / 2 = Class Mark
• Class Mark = midpoint of class size
• (<cf/N)100 = Cummulative Percent
