Data is a collection of facts, such as numbers, words, measurements observations or even just descriptions of things. when collecting data in a survey the following precautions must be taken to ensure that all results are unbiased 

• the sample of the population from whom the data is collected must be randomly chosen 
• the members of the sample must be proportional to the members of the population 
• the sample must not be too small as it would then be difficult to draw conclusions
