Quantitative Research

Over many years, I’ve worked with DHM on virtually every type of research as a client, a consultant, and a project partner in such wide-ranging sectors as utility taxes, land conservation community giving and the judiciary. Regardless of circumstance and without exception they've been deep thinkers from the start and deliver unimpeachable work, exceptional analysis, and invaluable insight.

Paul Vogel, Principal, Vogel Communications
DHM research is a highly respected leader in providing independent quantitative opinion research tailored to our clients’ needs. With every project, as with our qualitative research projects, we bring to our clients:
  • More than 40 years’ experience designing and conducting opinion research throughout the Pacific Northwest and United States.
  • Capacity to add value to strategic recommendations by drawing upon decades of extensive work assessing attitudes on a variety of issues.
  • Experience assisting public, private, and nonprofit clients with decision-making, including visioning, strategic planning, program evaluation, budgeting, and communications.
  • Clearly presenting and communicating research findings to diverse audiences, including businesses, elected officials, community leaders, and boards of directors through informative, insightful, and actionable presentations.

DHM strongly believes our clients are often best served with a combination of quantitative and qualitative research to learn not only how a population feels about an issue, product, or service, but to also learn why they feel that way.

Telephone Surveys

For many projects, telephone surveys remain the gold standard when it comes to random sampling and statistical reliability. DHM’s commitment to sound methodology ensures accurate and comprehensive insight. Sampling capability includes cell phones, smartphones, multi-lingual interviews, and database sourcing. DHM works with each client to carefully identify and access the target population to provide the information they need.

Online Surveys

Online research provides opportunities to connect with populations difficult to reach by telephone, and allows participants greater control over when, where, and how they participate. This generates highly useful information for clients. Online studies also are used as community engagement tools, and provide interested residents with opportunity to make their voice heard.

DHM conducts online panel research in Oregon monthly about current issues. We publish the data and analysis online and through select media partners, and use the insights to provide greater context for clients.  An online national survey is conducted for the same reasons three times a year. 

At DHM, we are experts designing and deploying valid and reliable online surveys.  There are many websites promoting their own methodology for online surveys that are inexpensive because users have to build, launch, and conduct their own survey. They seem user-friendly, and include wonderful testimonials.  But they do not have over 40 years of experience and expertise that DHM provides to assure a study is valid and reliable, including objective, third-party analysis and reporting.

Conjoint, Discrete, MaxDiff

These are advanced research techniques that help show how people make choices and decisions. These techniques, most easily administered online, enable DHM to significantly augment conventional research by providing a much more in-depth understanding of the choices that people make. Survey respondents are initially exposed to different choice configurations and are asked to choose which they prefer. The outcome reveals the attributes that are most important to them and the relative acceptance of each choice.  Although similar, each technique has its strengths relative to the number of attributes and attribute levels tested, nature of the information collected, and cost.

Mail Surveys

Mail surveys provide the widest reach, because almost everyone has a mailing address. In some instances mail surveys provide higher response rates (and perhaps more representative results) than telephone surveys or online surveys. We take explicit steps in the design and administration of mail surveys to assure valid and reliable data.

Delphi Method

Using the Delphi method, we conduct multiple rounds of surveys and/or online forums with topic experts to determine the range of opinions about particular matters, to test questions of policy relevance, and to explore or achieve consensus about disputed topics.

Mixed Methodology

We use proven research methodologies alongside innovative approaches to meet the unique needs of individual projects. Greater societal changes, including demographic shifts, diminished willingness to participate in surveys, and awareness of the need to give voice to hard-to-reach populations all influence our research methods.

In an example that combines mail and online research design, an invitation to an online survey is mailed to respondents. This provides the reach of mail surveys and the questionnaire control of online surveys.


The DHM team has deep expertise in analyzing quantitative data and identifying differences in attitudes and behavior by demographic and psychographic (i.e., values, beliefs, lifestyles) subgroups. We use a variety of statistical methods to uncover meaningful stories in the numbers.

In addition to traditional descriptive analyses and conjoint, discrete, and MaxDiff studies, DHM can also support any client through completion of more advanced inferential statistical analyses, including:

Regression analysis is a statistical analysis technique used to examine the relationship between an independent and a dependent variable. This helps the researcher model this relationship and predict and estimate the behavior of the dependent variable for any value of the independent variable.

Cluster analysis is the process of grouping similar observations into smaller, more homogenous groups within the larger sample population. This is used to organize the data into a meaningful structure or pattern.

Our reporting does more than highlight or review results that is easily read from the abstract.  Links among demographic characteristics and expressed attitudes are explored and examined. We focus on the implication of those links and how they can develop effective planning, policy making, and communications.

Our Partners

Research at DHM is conducted directly with clients across a wide range of organization and interests. Frequently, communication agencies, public affairs firms, consulting firms, and others partner with DHM to enhance understanding of awareness, values, beliefs, and messaging. DHM is proud to partner with these exceptional firms, and others.
