Organisation of data

The raw data can be grouped according to time. Such a classification is known as-----

• Spatial classification

• Chronological classification

• Qualitative classification

• Quantitative classification

Nationality, literacy, religion, gender, marital status, drinking habits etc are classified as:

• Quantitative

• Spatial

• Qualitative

• chronological

The frequency distribution of two variables is known as:

• Univariate

• Bivariate

• Multivariate

• None of these

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

• FREQUENCY DISTRIBUTION

• UPPER LIMIT

• LOWER LIMIT

• CLASS INTERVAL

Statistical calculations in classified data are based on:

• the actual values of observations

• the upper class limits

• the lower class limits

• the class midpoints

For a particular class boundary, the less than cumulative frequency and more than comulative frequency add up to:

• Total frequency

• Adjusted frequency

• either a or b

• None of these

For a discrete variable, the classification of its data is known as a----

• Frequency Array

• Univariate

• Bivariate

• None of these

Annual income of a person: or marks of a student are

• An attribute

• A discrete variable

• A continuous variable

• None of these

Tally marks determines

• class width

• class boundary

• class limit

• class frequency

In the construction of a frequency distribution, it is generally preferable to have classes of:

• equal class width

• unequal class width

• maximum class width

• None of these
