Ascription
In The Real World, You Must Deal with Missing Data
The Incomplete Data Problem
No matter how well a market research
project is planned and executed, the reality is that there are usually some responses which are partially
incomplete. Dealing with these holes in your data is a delicate matter. Leaving them in could distort the
distributions. In addition, some systems cannot handle the empty values. Throwing away the responses is
wasteful and going back to the field would not be economically feasible and cannot maintain the statistical
integrity of the project.
The Ascription Solution
The best solution is to ascribe the data
using statistical methods whereby the ascribed data will have the same distribution as the original
distribution of the non-empty data cells.
Two Ascription methods
SM Research offers two technologies that
can be applied during the ascription process. The first involves accumulated distribution filling, which
fills empty cells with no special conditions. The second technology is called key demographic matching which fills the holes with the answers from
matched demographic respondents.
Both methods will create a non-distorted, no black-hole dataset that can be used in further studies.
