ORGANISATION OF DATA

In a series, the number of times an item occur is known as:

• Number

• Frequency

• Class Frequency

• Cumulative frequency

The difference between the upper limit and the lower limit of a class is known as:

• Range

• Magnitude of a class interval

• Frequency

• Class Limits

Which of the following series have classes-

• Continuous

• Individual

• Discrete

chronological tabulation is based on

• time

• location

• both

Class mark =

• Upper limit -lower limit/2

• upper limit +lower limit/2

• none

......................CLASSIFICATION IS DONE ACCORDING TO THE ATTRIBUTES OF DATA.

• QUANTITATIVE CLASSIFICATION

• QUALITATIVE CLASSIFICATION

• CHRONOLOGICAL CLASSIFICATION

• SPATIAL CLASSIFICATION

................. IS THE THE DISTRIBUTION OF OBSERVATIONS OVER SEVERAL VALUES

• FREQUENCY DISTRIBUTION

• UPPER LIMIT

• LOWER LIMIT

• CLASS INTERVAL

............IS THE WIDTH BY FINDING DIFFERENCE BETWEEN UPPER AND LOWER LIMITS OF THE CLASS

• MID POINT

• CLASS INTERVAL

• CLASS FREQUENCY

• LOWER LIMIT

............IS THE SERIES WHERE OBSERVATIONS ARE ALL PUT INTO ONE COLUMN AND NOT LISTED IN GROUPS

• INDIVIDUAL SERIES

• DISCRETE SERIES

• CONTINUOUS SERIES

MID POINT IS EQUAL TO:

• (UPPER CLASS LIMIT + LOWER CLASS LIMIT) / 2

• (UPPER CLASS LIMIT - LOWER CLASS LIMIT) / 2
