Quantitative Market Surveys

Phone Surveys

Random probability samples can be generated from firms such as Survey Sampling, Inc. (SSI)

Best for mostly close-end questioning, when dimensions and ranges of issues are known.

Success depends highly on filtering sample to those consumer or business users who find topic or category relevant.

10-12 average interview length is maximum target unless highly specialized population or incentives paid.

Optimum use is for top-of-mind awareness, branding and brand comparisons, and perception studies.

Response rate is critical, especially with growing privacy issues and phone screening among consumers and business executives alike.

Low relative cost 

Generally, fast implementation.

Skilled interviewer can extract more information than a self-administered method (mail, online)

Critical to monitor response rate to ensure sample is representative of target sampling frame.

Personal Interviews

and

Central Location Interviews

Random probability sample -OR- convenience sample, depending upon design.  (Central location usually use a convenience sample, i.e. mall traffic)

Used where a face-to-face environment is desired.

In B2B market research, personal interviews may be done by appointment where interviewer goes to respondent's office.

Some special consumer studies may be done in-home by appointment.

Often respondents are recruited to come to a central location, or recruited from mall traffic to a nearby office to conduct interview.

Used for complicated or sensitive issues, B2B market research environments, or where extensive physical or visual display requirements exist along with need for specialized interviewing skills (depth probing, time for evaluation and reaction.)

High cost. 

Can provide good hybrid method combining features of qualitative and quantitative research by asking quant-type questions first, followed by in-depth probing questions and projective techniques.

Skilled interviewer can extract more information than a self-administered method (mail, online)

Online Surveys

(Web Surveys)

Can employ true random probability sampling

Complicated survey questionnaire formats can be used. For example, piping, rating, rankings, constant sum questions, etc.

Easy to display visual information previously available only in a face-to-face interview format. (advertising copy, concept statements, projective stimuli, etc.)

Allows deployment of complicated respondent tasks. (card sorts, conjoint ratings, etc.)

Low relative cost 

Generally, fast implementation.

Sampling control is critical.

Large pre-recruited panels allow quick access to willing respondents, although sampling validity must be carefully assessed.

Hybrid Surveys -- Methods

Hybrid methods combine two or more techniques to optimize response or measurement validity. 

Examples:

>Mail or phone invitation to online surveys.

>Online surveys with phone follow-up to permit depth probing of key market research questions by expert interviewer.

>Quantitative surveys from which participants are selected based on their answers for a follow-up qualitative phase (focus group, depth)

>Panel recruited from a one-time quantitative survey. (see Panel Research FAQ)

Higher cost  

More time required for implementation.

Enhances quality through higher response rates, and better response quality or validity.
