The cumulative frequency gives us the number of observations lying below or above a particular value of a variable. Cumulative frequencies are of two types : a) Less than type, b) more than type.
- Less than type: We calculate the number of observations lying below each value of the variable. As the values increase we keep on adding the corresponding frequencies to get the cumulative frequency.

Example 1: The weights of 36 pumpkins from a vegetable market are recorded and presented as a frequency distribution table :

The table shows that there are 6 pumpkins weighing 4 kg, but there are 30 pumpkins weighing 4kg or less. Similarly there are 35 pumpkins having weight not more than 6kg.

This can be represented graphically as in figure 1.

Although victim characteristics is only one of many aspects considered in theoretical victimology, which studies the victim factors in the crime (Fattah, 2000), these characteristics has been found influential in the planning and eventual commission of the crime. Since the history of this field of study, there was a running belief that the victim may have a contribution in the genesis of the crime.

However, many parameters such as humidity, materials of manufacture of the ball, size of the ball, etc. control the movement of the ball in air. Research on golf balls and tennis balls reveal their aerodynamic properties and the various parameters affecting their flight. The effect of seams on a baseball on the flight has been evaluated along with the relationship between rotation and lateral forces (Watts & Sawyer 1987).

Asepsis

Microorganisms are the tiny microscopic structures that cannot be seen with naked eyes. They are present on all the living things and also in the environment. Some of these microorganisms are non pathogenic that is they do not cause any disease. However, many of the microorganisms are pathogenic in nature. The pathogenic microorganisms can cause disease or infections. Absence of these pathogenic microorganisms is known as asepsis.

Importance of asepsis

Asepsis is usually carried out in the laboratory mostly while dealing with microorganisms. The techniques used to carry out asepsis are known as aseptic techniques. If aseptic conditions are not maintained in ...

In naming this piece, Damien Hirst compels us to confront the message of End Game: our vanity and mortality.
