Surveys are a key tool in collecting information about a "population", whether that population is a set of people, households, businesses or even pieces of equipment. Most surveys use information from a subset or sample of the population, which if done right will lead to an understanding of the whole targeted population. Such sample surveys require proper statistical input in their design and analysis.
Surveys can be a major investment, with results often playing an important role in strategic planning decisions. Therefore, it is critical to invest in a good design, good implementation and the best analysis. Data Analysis Australia's statisticians and survey researchers have years of expertise, specialising in ensuring surveys meet the individual needs of our clients.
Data Analysis Australia consultants can advise on all aspects of survey design, implementation and reporting:
- The implementation of a survey can use a mixture of collection techniques or modes, including telephone interviews, face-to-face interviews, door-to-door interviews, self completion forms and on-line questionnaires. Each method has its particular strengths, weaknesses and costs and for each survey Data Analysis Australia can guide the client so the right choice is made, and the best results achieved.
- A well designed questionnaire is vital to ensure that the information collected is accurate, unbiased and, most importantly, gathers the information needed to address research issues. Analysis of past survey results can sometimes provide valuable information for a new questionnaire, eliminating ineffective questions and directing resources to areas of more value.
