Since we can’t subject the qualitative results to statistical analysis, as in quantitative data, you should employ them with care. As the name implies, a thematic analysis involves finding themes. And yes, you can apply useful statistical analyses even when dealing with small sample sizes. Statistical Analysis is the science of collecting, exploring, organizing, exploring patterns and trends using one of its types i.e. Within-Subjects: 1 group of participants is recruited and performs tests under all conditions. 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). Common qualitative techniques in design research include contextual analysis, ethnography, structured interview, and observation. This course is a base to all the analytical studies and research studies. If an experiment requires participants not to learn a behaviour between a set of task then between subjects is more suited. When you do the research with many participants, your data tend to be closer to the true population. Knowing these two research method will help to conduct UX research effectively. More specifically this post will look at the types of behavioural research, how to prepare data, and the factors to consider when running descriptive statistics including comparing means and the different variables in a test. 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). Data – both quantitative and qualitative – informs decision-making for design direction. Statistical analysis experts help collect, study and extract relevant information from vast and complex data. Statistical analysis reveals changes in UX quality.

UX Research is one of the key activities of the UXDT Division of National Informatics Centre. Statistical analysis is, according to one service provider, "the science of collecting, exploring and presenting large amounts of data to discover underlying patterns and trends." Statistical analysis is used in order to gain an understanding of a larger population by analysing the information of a sample. In many studies, 3 or more conditions need to be compared. No previous knowledge needed. Easier to organize – Organizing an in-person UX testing session does require a good deal of logistics: agreeing the date and time, figuring out travel plans, booking a room for testing, purchasing additional equipment, and much more. Some examples of dependent and independent variables in the context of UX design are as follows (Lazar et al., 2009): 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). Boston: McGraw Hill. However, statistics like analytics only identify behaviour.
