Answer» i. Width of the class: The difference between the upper and lower limits of class called width of the class. It is denoted by c or i. i/c = Upper limit(UL) – Lower limit(LL) ii. Class mid point: The central value of a class called mid value/point; m/x = LL+UL/2 iii. Define Frequency Density: The frequency per unit of class interval is the frequency density. i.e. frequency density = (Frequency the class/width of the class) = f/w iv. Relative frequency: Relative frequency.. is the ratio of frequency of class to the total frequency of the distribution Relative Frequency f/N. |
