CUSTOMIZED PROJECT DESIGN

• DESIGNING YOUR SAMPLE 

CSR helps you decide on a sample size that suits your study objectives, design, and budget. We offer:

 Random Digit Dialing Samples:

• Computer generated telephone numbers targeted to your  study area produce representative samples of residential  households, including both listed and unlisted numbers. 

Targeted Samples:

• CSR can design your sample to increase the chances of  reaching the population subgroups of interest to your  study. 

Listed Samples:

• 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. 

• INSTRUMENT DEVELOPMENT

Writing Questions:

• 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. 

Question Order:

• We can advise you on proper sequencing of items, a  critical design feature for maintaining objectivity and  ensuring that respondents understand your study. 

Sensitive Questions:

• Several effective strategies may be employed to elicit  confidential or personal information that may be crucial  to your study. 

Pre-testing:

• 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. 

PROFESSIONAL INTERVIEWING AND DATA COLLECTION

• COMPUTER ASSISTED TELEPHONE INTERVIEWING 

Computer-Assisted Telephone Interviewing (CATI) increases the efficiency, accuracy, and flexibility of surveys, operating in the background while the trained interviewer asks the questions and probes for accurate responses. The computer system stores a data base of phone numbers and streamlines the process of sampling numbers, dialing, scheduling call-backs, and recording the outcome of each call attempt. Accurate, instantaneous data entry is assured by the CATI system: questions appear on a computer screen in programmed sequence for interviewers, and responses are recorded directly in the computer. The costs and inaccuracies of separate data entry are eliminated. View our CATI lab.

• SPECIALIZED INTERVIEWING 

When you need to survey organizations or businesses, CSR interview specialists can get answers from busy professionals. Our trained interviewers can also manage complex quota designs or mixed data-collection modes.

• MAIL SURVEYS 

CSR uses the "Tailored Design Method" to organize multiple mailings that maximize response rate and minimize non-response bias. CSR can do your questionnaire layout work in-house.

Additional data collection services offered by CSR include: 

• Web survey design
• semi-structured in-depth interviewing via telephone 
• mail surveys using electronic CATI/CAPI techniques on diskette or via computer networks 
• focus groups 

STATISTICAL ANALYSIS

• descriptive statistical analysis of survey responses 
• cross-classification analysis with demographic or other predictive factors 
• adjustments for stratified and strategic sampling 
• multivariate analysis: ANOVA, linear and non-linear regression, logistic response models, categorical methods 
• comparisons over time, longtitudinal analyses 
• sensitivity analysis, significance testing 
• content analysis of open-ended responses 
• matching to U.S. Census and other geosocial data 
• data entry from your questionnaires
