What is data editing and data coding?
Data editing: Information altering is characterized as the procedure including the audit and alteration of gathered study information. The intention is to control the nature of the gathered information. Information altering can be performed physically, with the help of a PC. Data coding: Coding is an explanatory procedure in which information, in both quantitative structure is sorted to encourage examination. Coding means the change of information into a structure justifiable by PC programming.
What are the elements of data analysis?
editing coding classification calculating measures testing
The advantages and disadvantages of primary data?
Advantages and Disadvantages of primary data are: Advantages 1. Data is basic 2. Unbiased information 3. Original data 4. Data from the primary market/ population 5. Data direct from the population. Disadvantages. 1. Large volume of data. 2. Huge volume of population. 3. Time consuming 4. Direct and personal intervention has to be there. 5. Raw data.
What are 3 advantages of data validation?

What are the advantages of performing a database normalization?
There are many advantages of performing a database normalization. Some of the advantages include faster index searching, data commands are faster with less indexes and a more compact database with less null data.
Define line coding in data communication?
process oftransfer of digital data to digital signal is known as line coding
What is the features and the advantages of coding system in an organisation?
A coding system in an organization typically involves standardized codes for categorizing and organizing data, products, or processes. Key features include systematic classification, easy retrieval of information, and enhanced communication among departments. Advantages include improved efficiency, reduced errors in data handling, and streamlined operations, leading to better decision-making and resource management. Overall, a well-implemented coding system fosters consistency and clarity, facilitating growth and scalability.
What are the advantages and disadvantages of coding data?
Coded Data is used to lessen the number of keystrokes used when inputting data. For example, entering 'F' rather than Female and 'M' rather than Male. This was the user is less likely to make a spelling mistake; they will save time and they will also save file storage space. However the user may not understand the exact coding rules and therefore make mistakes in the first instance; it will take longer to train the user and incorrect entries in a database can cause untold number of errors or mistakes.
What is data coding?
Coding data means condensing large data sets into codes to represent the data and to allow processing to be more effective as well as producing more useful information for the user

What are the advantages of shanon fano coding?
Shannon-Fano coding offers several advantages, including simplicity and ease of implementation, making it accessible for basic data compression tasks. It effectively reduces the average length of encoded messages by assigning shorter codes to more frequent symbols, thus optimizing storage and transmission efficiency. Additionally, it is a prefix coding method, ensuring that no code is a prefix of another, which allows for unambiguous decoding. However, while it is straightforward, it may not yield the optimal compression compared to more advanced methods like Huffman coding.
What are the Advantages of arithmetic coding over Huffman coding?
1.the compression ratio is higher compared to huffman coding. 2.efficiency is greater comparatively. 3.Redundancy is much reduced.

What advantages does the Internet offer as a consumer and business communications medium?
There is no need for data entry or interviews, and responses are collected automatically, saving time and money while eliminating coding errors and interviewer bias.
