Organisation of Data

Why is the organization of data considered an essential step in statistical analysis?

1. It replaces data collection.
2. It prepares raw data for meaningful presentation, analysis, and interpretation.
3. It eliminates the need for sampling.
4. It guarantees perfect conclusions.

Which of the following is the main advantage of organizing data?

1. It increases the amount of raw data.
2. It makes data easier to understand, compare, and analyze.
3. It eliminates the need for statistical methods.
4. It changes the original observations permanently.

Which type of frequency distribution is suitable for variables such as examination marks or income?

1. Qualitative distribution only
2. Continuous frequency distribution
3. Chronological distribution only
4. Geographical distribution only

In a frequency distribution, frequency refers to:

1. Total number of classes
2. Number of times a value or class occurs
3. Width of a class interval
4. Difference between class limits

What is a class interval?

1. Difference between highest and lowest values only
2. Difference between the upper and lower limits of a class
3. Total number of observations
4. Number of classes in a table

The difference between the highest and lowest observations is called:

1. Class interval
2. Range
3. Frequency
4. Midpoint

A frequency distribution is:

1. A list of observations arranged randomly
2. A table showing the number of observations corresponding to each value or class
3. A graphical representation only
4. A method of calculating averages

Classification of data according to place or region is called:

1. Chronological classification
2. Geographical classification
3. Quantitative classification
4. Qualitative classification

Classification of data according to time is known as:

1. Geographical classification
2. Chronological classification
3. Qualitative classification
4. Quantitative classification

Classification based on qualities such as gender or religion is called:

1. Quantitative classification
2. Qualitative classification
3. Chronological classification
4. Spatial classification

Which type of classification is based on measurable numerical values?

1. Qualitative classification
2. Quantitative classification
3. Chronological classification
4. Geographical classification

Classification of data means:

1. Randomly selecting observations
2. Grouping data into homogeneous categories based on common characteristics
3. Deleting unnecessary observations
4. Calculating averages

Arranging observations in ascending or descending order is called:

1. Classification
2. Array
3. Tabulation
4. Coding

Which of the following is known as raw data?

1. Data arranged in a frequency table
2. Data presented in graphs
3. Data collected in its original, unorganized form
4. Data arranged in ascending order

What is the primary objective of organizing data?

1. To increase the quantity of data collected
2. To arrange data systematically for easy understanding, analysis, and interpretation
3. To eliminate all observations from a dataset
4. To convert qualitative data into mathematical formulas only
