This class will teach you the statistics needed to understand and analyze the numbers you get from UX research, and the types of inferences you can draw from such numbers. Any statistical methods used for a study should be Wrong method selection and misinterpretation of results can lead to false/inaccurate conclusions (Lazar et al, 2010). Become familiar with all the question formats and consider their analysis potential for your research … Delwiche, L. and Slaughter S. (2008) The Little SAS Book: A primer, 4th Edition. For more information on the measures refer to Hinkle, Wiersma, and Jurs, (2002) and Rosenthal and Rosnow, (2008). Only after identifying these is it possible to select the appropriate test group type (within-group vs between-group) and significance test to apply. With so much data available digitally, additional value can be gained by combining in-depth user research with expert data analysis. Using the Data Analysis tools, the dialog for correlations is much like the one for descriptives - you can choose several contiguous columns, and get an output matrix of all pairs of correlations. This is done to identify and rectify errors and mistakes in the data that might contaminate the entire data set, to identify higher level coding themes and to organise the data into predefined layouts or formats depending on what software is being used (Delwiche and Slaughter, 2008). Data export. Visit PayScale to research ux researcher salaries by city, experience, skill, employer and more. Data – both quantitative and qualitative – informs decision-making for design direction.

When comparing two groups or conditions independent samples t test and the paired-samples t test can be used. All research studies should be based on questions or hypotheses. Descriptive investigations, such as surveys and focus groups, are often the first step of a research project, that focus on identifying an accurate description of a situation or a set of events. Glaser and Strauss originally created these grounded-theory techniques in 1967. Houghton Mifflin Company. Many UX professionals are intimidated by quantitative data analysis and often stick to qualitative research methods. Statistics are useful when conducting design research to answer specific questions. The research methodology of grounded theory requires adhering to a set of principles that form the backbone of grounded theory. 10 Best Practices for Competitive UX Benchmarking —tips for running competitor usability tests. time to complete task). Providing meaningful opportunities for users to experience (rather than simply read about) features. Unlike web analytics, the relationships between variables can be tested to determine “why” something happens. Cary NC: SAS Institute Inc. Hinkle, D. Weirsma, W., and Jurs, S. (2002) Applied Statistics for the Behavioral Sciences, 5th edition. When research data should be trusted; what statistics to use when. Preparation and collection of data is essential for grouping and interpreting the data sets and results. Statistical analysis allows addressing a broad range of different research questions through online surveys. However, due to variances in the data it is not possible to directly compare the means of multiple conditions at the same time (Lazar et al, 2010). Once you've conducted UX research, you need to analyze it in order to glean valuable insights. Instead, statistical significance tests need to be used to evaluate the variances. Statistical analysis experts help collect, study and extract relevant information from vast and complex data. Copying, stealing, and inspiration: how to do competitor research —more detail on my approach to competitor research. Statistical analysis allows inferences to be drawn about target markets, consumer cohorts and the general population by expanding findings appropriately to predict the behaviour and characteristics of the many based on the few. Knowledge and understanding of the various factors and careful thinking is required to establish what are the number of conditions, groups and variables associated with the projects predefined hypothesis(es). Applied to a UX design project this information is useful to identify specific user groups. Knowing these two research method will help to conduct UX research effectively. There are many factors to consider when conducting statistical analysis. Common qualitative techniques in design research include contextual analysis, ethnography, structured interview, and observation. This is part 2 of Advanced User Research Techniques. The way you communicate your findings can differ greatly depending on the stakeholders involved. UX Research matrix with various methods Quantitative research is a methodology used to validate or invalidate hypotheses about people’s behaviours. The ultimate aim for any researcher conducting user studies is to find out whether there is any difference between the conditions or groups (Lazar et al, 2010). Experimental studies are often used in the field of medicine to identify treatment methods for disease or to create better drugs. It's suitable for those new to quantitative research. Coding involves assigning a numerical value to a response. The median measures the middle score of a data set, and mode measures the value with the greatest frequency in a data set. Great question! G (2000) A First Course in Design and Analysis of Experiments. When the interviews and observations are done, UX researchers are often left with a mountain of data and only a faint idea of what to do next. As the name implies, a thematic analysis involves finding themes. How can we provide better user experiences? This five-day short course will give you acomprehensive introduction to the fundamental aspects of research methods and statistics. They allow for better understanding of data and for teams to talk confidently in the numbers. In any test, independent and controlled variables are conditions the researcher can control while dependent variables are usually outcomes the researcher needs to measure (Oehlert, 2000). Data collected from experiments, usability tests, field studies and surveys needs to be carefully processed before statistical analysis can be conducted. As a method of UX research, task analysis enables designers to learn about their users' goals & observe the actions they take to achieve them.

Relational investigations enable discovery of connections between events (spelling ability) and variables (amount of time spent reading). The central tendency is where the bulk of a data is located and can be measured by the mean, median and mode (Rosenthal and Rosnow, 2008). and Schindler. New York: Freeman and Company. Jeff Sauro talks to Gerry Gaffney about quantifying UX. The UX Researcher’s work is to provide answers to the most challenging questions in the product’s design. MacKenzie, S. (2013). Commonly used ANOVA tests include one-way ANOVA, factorial ANOVA, repeat measure ANOVA and ANOVA for split-plot design (Lazar et al, 2010). This relates to how much the data points deviate from the center or how spread out the data set is. Between-Subjects: 2 groups of participants are recruited and each group performs tests under different conditions. Tags. However, for industries that would result in harm to an individual or extreme severity of circumstance such as in medicine, airline engine turbines or banking software the use of statistics would play a vital role. For example, evaluating the effectiveness of two checkouts; group one uses Amazon checkout to purchase a book, group two uses Ebay checkout to purchase a book. Our purpose-built research facility includes a user testing area and separate control room to achieve the optimal testing conditions. No previous knowledge needed. It can tell how a situation or set events occurred and, in some experiments, why it happened. Statistical analysis is used in order to gain an understanding of a larger population by analysing the information of a sample. If the probability of the difference is less than 5% then a claim with high confidence can be made that the observed difference is due to the difference in the independent variables (Lazar et al, 2010). UX research interviews: what to expect (part 2), How I wound up being a Quantitative UX Researcher. If the mean of one group is much higher than another group, significance tests, such as a t test can examine if the difference is statistically significant (Lazar et al, 2010). UX researchers typically borrow research techniques from grounded theory—whether knowingly or not—when analyzing data from studies. Measuring users’ reactions Every UX designer faced with a 6-inch stack of research notes and a looming deadline has wanted to take a nap and wake up with the most important insights neatly tagged. Statistical Analysis courses from top universities and industry leaders. In UX, we often collect and report numbers: how many people completed the tasks, what the mean satisfaction rating was, how many users converted with design A compared with design B. Controlled variables: These are the measurements and methods used to measure the change in the independent variable. The other important group of descriptive measurement is the measure of spread (Lazar et al, 2010). Using Quantitative and Qualitative Research Together . Learn Statistical Analysis online with courses like Business Statistics and Analysis and Satellite Imagery Analysis in Python. However, relational studies are not suited for determining the causal relationships between multiple factors (Cooper and Schindler, 2000; Rosenthal and Rosnow, 2008). James Mordy A voracious reader, an avid researcher, a logophile, and a tech geek he loves to read about the latest technologies that are shaping the world. Applied to agile software development the use of statistics may be difficult to implement due to quick iterations. Boston: McGraw Hill. Descriptive Type (for describing the data), Inferential Type(to generalize the population), Prescriptive This might be insightful however, it does not establish if there are correlations or relationships between factors or explain why certain things happen. The mean measures the “arithmetic average” and can be used to show how groups relate to each other. When you do the research with many participants, your data tend to be closer to the true population. There are two main types of user research: quantitative (statistics: can be calculated and computed; focuses on numbers and mathematical calculations) and qualitative (insights: concerned with descriptions, which can be observed but cannot be computed). The first post in this series discusses Analytics as an Advanced User Research Technique. Frequently used research methods for studying interfaces and applications, such as, observations, field studies, surveys, usability tests and controlled experiments are all kinds of empirical investigations that can be catagorised into three groups: descriptive investigations, relational investigation experimental investigation (Shneiderman et al, 2009; Rosenthal and Rosnow, 2008).
