What is 'En-Coding' ? It is the process of shorting data in a database and or spreadsheet into codes like M = Male or F = Female
What are the 'Advantages' of Encoding Data? 1.Speeds up data entry as the codes are short and the user may click to select the code from a list 2.Reduces the chance of errors in Data Entry as there is less to type in 3.Codes are shorter than original data, so saves disc storage
What are the 'Disadvantages' of Encoding Data? 1.Coarsens data by fitting it into small number of groups (categories) 2. Value judgments needed to fit data into a certain group (category), so selection of category by data entry staff may not be consistent.
What is meant 'En-Coding Value Judgments' These are judgments when in a question say what its about; E.g What do you think of these Flashcards? Poor,Average, Good?
'En-Coding Value Judgments' have many issues with them. These are: 1. They are subject to personal opinion; E.g a persons good could be another persons poor. 2.They can be very difficult to En-Code without some loss in detail.
