Structured Data Analysis (which is more commonly known as Statistics) helps us to better understand data by looking at different kinds of information (or "structures") and the relationships between them. For example, if we wanted to know how people of different ages responded to a survey, we could use Statistics to look at all the different age groups and see how they answered the questions. By doing this, we can better understand how people from different age groups responded to the survey and this can help us make better decisions.
