Problems of Missing Values in Marketing Researches
Original language description
The paper gives a list of methods suitable for processing the data file with missing values. We focus on such methods which are useable without a need of the special statistical software. The choice of a certain method depends on various factors. The most important factors are type of a variable and a variability of a sample. Both samples with a high variability and samples with a low variability are researched. The used methods are compared then in term of their impact on sample properties. There are presented the methods suitable for work with ordinal, interval and ratio variables. Each of them has its own characteristics which cannot be missed out by a choice of the method. Lastly, the paper deals with the problem whether it is better to replace missing values or to work just with the data truly obtained.
