❶Results are compared with results from groups not exposed to the variable. In other projects Wikimedia Commons.

In correlational research the survey is conducted on a minimum of two groups. In most correlational research there is a level of manipulation involved with the specific variables being researched. Once the information is compiled it is then analyzed mathematically to draw conclusions about the affect that one has on the other.

Remember, correlation does not always mean causation. Typically, you should not make assumptions from correlational research alone. Causal-comparative research looks to uncover a cause and effect relationship.

This research is not conducted between the two groups on each other. Rather than look solely for a statistical relationship between two variables it tries to identify, specifically, how the different groups are affected by the same circumstance.

As always the use of statistical analysis is engaged to synthesize the data in a clear method for presentation. Though questions may be posed in the other forms of research, experimental research is guided specifically by a hypothesis. Sometimes experimental research can have several hypotheses. A hypothesis is a statement to be proven or disproved. Once that statement is made experiments are begun to find out whether the statement is true or not. This type of research is the bedrock of most sciences, in particular the natural sciences.

It will help you use the types of quantitative research to great effect. Quantitative research can be exciting and highly informative. It can be used to help explain all sorts of phenomena. The best quantitative research gathers precise empirical data and can be applied to gain a better understanding of several fields of study. The world of information is waiting for you.

List and explain the four approaches to quantitative research. Provide an example of each method. Describe how to identify the appropriate approach for a particular research problem.

Quantitative analysis of the percentage of participants who created similar groupings can help establish which categorization approach would be understandable to most users. For example, imagine your product is a pet-supplies website, and this is your top-level hierarchy.

You might ask your participants in one task to find the dog collars. Quantitative analysis of the tree-test results will show whether people were able to find the right path to this item in the information hierarchy. How many participants picked the wrong category? Surveys are a flexible user-research tool. You can administer them in a variety of contexts — as short intercept surveys on a live website, in emails, or after a usability test.

They can produce combination of quantitative and qualitative data — ratings, proportions of answers for each choice in a multiple-choice question, as well as open-ended responses.

You can even turn qualitative responses to a survey into numerical data see the following section on coding qualitative comments. Even if you create your own custom questionnaire, you can still track your average scores over time, to monitor product improvements. From Strategy to Requirements to Design. This technique is less of a data-collection methodology, and more of an analysis approach for qualitative data. It involves grouping observations from a qualitative study for example, a diary study, survey, focus group, or interviews based on common themes.

If you have a lot of observations, you can count the number of instances when a particular theme is mentioned. You may count the instances when people used the product at work, in their homes, or on the go.

This method can identify the prevalence or frequency of a specific theme or situation — for example, the frequency of a user complaint or of a UI problem. This approach is a good way to mine numerical data from large amounts of qualitative information, but it can be quite time consuming. These studies can be customized depending on your research questions, but they generally involve first exposing participants to your product either by showing them a still image or by asking them to use the live product or a prototype.

With a large sample size that is representative of your population, trends start to emerge. Eyetracking can help you identify which interface and content elements need to be emphasized or deemphasized, to enable users to reach their goals. A major obstacle to running eyetracking studies is the highly specialized, prohibitively expensive, and somewhat unstable equipment that requires lots of training to use.

When trying to determine which quant method to use, lead with your research question. What do you need to know? There are some grey areas within those recommendations, however.

There are four main types of quantitative research designs: descriptive, correlational, quasi-experimental and experimental. The differences between the four types primarily relates to the degree the researcher designs for control of the variables in the experiment.
