Statistical analysis of a functional neuroimaging data set considers the importance of statistical approaches to attributing brain states to behavioral states, and to defining the strength of study inferences, and data-analytical approaches to defining behavior as processes of functional segregation (modularity) versus integration of brain activity.
Despite the importance of statistical concepts to health professionals, the teaching of statistics to students from this field has generally been unrewarding.
Of particular importance, the statistical properties inherent to the MVI data structure permit calculation of standard errors, confidence intervals and statistical tests allowing quantitative comparisons among MVI values.
Even if selection bias is not thought to be a major problem within a study, loss of participants because of not wearing the accelerometer for the required time could have importance for statistical efficiency and may reduce the potential for studies to make definitive conclusions because of lack of statistical power.
Nate Silver's accurate forecasting of Obama's election victory last year brought him acclaim, and it also highlighted the importance of statistical literacy in our data-heavy age.

The problem is that, unless you're a close follower of climate science, the overriding importance of statistical trends—as opposed to spot measurements can be baffling to lay people.
There is no disputing the importance of statistical analysis in biological research, but too often it is considered only after an experiment is completed, when it may be too late.
In this editorial we critically analyze the real data of this noninferiority study and the importance of statistical knowledge by oncologists for correct interpretation of study results.
Drawing from the authors courses on the subject as well as the first authors more than 30 years working in the pharmaceutical industry, Clinical trial methodology emphasizes the importance of statistical thinking in clinical research and presents the methodology as a key component of clinical research.
