Both qualitative and quantitative methods of user research play important roles in product development. Data from quantitative research—such as market size, demographics, and user preferences—provides important information for business decisions.

Qualitative research provides valuable data for use in the design of a product—including data about user needs, behavior patterns, and use cases. Each of these approaches has strengths and weaknesses, and each can benefit from our combining them with one another.

Quantitative studies provide data that can be expressed in numbers—thus, their name. Because the data is in a numeric form, we can apply statistical tests in making statements about the data.

These include descriptive statistics like the mean, median, and standard deviation, but can also include inferential statistics like t-tests, ANOVAs, or multiple regression correlations MRC.

Statistical analysis lets us derive important facts from research data, including preference trends, differences between groups, and demographics.

Multivariate statistics like the MRC or stepwise correlation regression break the data down even further and determine what factors—such as variances in preferences—we can attribute to differences between specific groups such as age groups.

Quantitative studies often employ automated means of collecting data such as surveys, but we can also use other static methods—for example, examining preferences through two-alternative, forced-choice studies or examining error rates and time on task using competitive benchmarks.

Some respondents may feel that President Obama is too liberal, while others may feel that he is too conservative in his actions, but without the necessary data, there is no way to tell. Only someone with a firm grasp of how they should use and interpret quantitative statistics should conduct such a study.

In a product-development environment, this data deficiency can lead to critical errors in the design of a product. Additionally, only someone with a firm grasp of how they should use and interpret quantitative statistics should conduct such a study. For most tests, there is an overreliance on the p-value and sample size.

The p-value is a statistic that indicates the likelihood that research findings were the result of chance. If a p-value is less than.

If your study is underpowered because of its having two small a sample size, you may fail to achieve statistical significance—even if the finding is accurate. The reality is not too far off. However, it is possible to increase sample sizes to a point where statistical significance is barely meaningful.

In such a situation, it is important to look at the effect size —a statistic that tells you how strongly your variables effect the variance. Basically, statistical significance tells you whether your findings are real, while effect size tells you how much they matter.

Typically, if you are able to achieve statistical significance with a smaller sample size, the effect size is fairly substantial.

It is important to take both statistical significance and effect size into account when interpreting your data. Qualitative Studies Qualitative research studies can provide you with details about human behavior, emotion, and personality characteristics that quantitative studies cannot match.
