DESIGNING YOUR SAMPLE
CSR helps you decide on a sample size that suits your study objectives, design, and budget. We offer:
Computer-generated telephone numbers targeted to your study area produce representative samples of residential households, including both listed and unlisted numbers.
CSR can design your sample to increase the chances of reaching the population subgroups of interest to your study.
Sometimes the most cost-effective route to a good sample is from a list that you supply or that CSR obtains for you.
CHOOSING THE RIGHT MODE OF DATA COLLECTION
CSR can advise on the most productive and cost-effective method of collecting your data: telephone, mail, electronic, or in-person. We ensure scientific validity for your study by helping to specify procedures for selecting respondents within households, securing cooperation, and following up incomplete interviews or questionnaires.
CSR can write questions for you or assist you in drafting your own. We ensure that the responses to your questions provide the information necessary to your study.
Scales and Measures
CSR will help you determine the best question formats to measure people's opinions, experiences, attitudes, and behavior.
We can advise you on proper sequencing of items, a critical design feature for maintaining objectivity and ensuring that respondents understand your study.
Several effective strategies may be employed to elicit confidential or personal information that may be crucial to your study.
Before a survey is implemented, CSR will test your instrument in the field. We will then work with you to eliminate any problems with questionnaire design, wording, definition of terms, response categories, programming, sequencing, or timing.
