Helping students build confidence with data and statistics
For many science students, statistics is where maths anxiety resurfaces most strongly. Even those comfortable with basic numeracy can lose confidence when they encounter datasets, variation, or the challenge of choosing the right statistical approach. The worry of “getting it wrong” can overshadow the curiosity that should guide scientific inquiry.
As science degrees place greater emphasis on research projects, evidence evaluation and independent analysis, this anxiety becomes more visible. Students worry about misinterpreting a dataset or applying the wrong test, and that hesitation often limits their confidence during practical classes, report writing, or final year research.
Understanding the challenge
Educators across disciplines have noted that statistics introduces a kind of “second wave” of anxiety, frequently reporting that while students can manage basic calculations, confidence drops when they move into statistical principles or applied data handling. For international students, or those returning to study after time away from education, statistical terminology and expectations can feel unfamiliar. For neurodiverse students, the cognitive load of managing new concepts and symbolic notation can add an extra layer of pressure.
This contributes to an uneven starting point, making it harder to build the shared foundation needed for confident data interpretation. Effectively tackling this requires inclusive approaches that build confidence gradually.

“A major opportunity lies in addressing the deep-rooted fear of failure that many students develop from an early age. Long before they reach university, students often become conditioned to view mistakes as something to avoid, rather than as a natural and essential part of learning. In science, however, “failure” is fundamental: the ability to design experiments, encounter unexpected outcomes, and iteratively refine ideas is a critical skill for any scientist. In parallel, modern scientific careers are increasingly data-driven. Success in research now depends not only on subject knowledge, but also on the confidence to handle, manipulate, analyse, and interpret complex datasets. Embedding structured digital literacy and data handling earlier in the curriculum, alongside explicit teaching that normalises failure, iteration, and resilience, is essential for reducing anxiety and for preparing students to succeed in the working world.”

Inclusive approaches that build confidence
Across the sector, educators are redesigning early statistics teaching to reduce pressure and build security in the learning process. Dr Alison Hill and Dr Courtney Tremlett at the University of Exeter and Dr Michelle Cordingley at the University of Chester have been embedding more transparent, scaffolded, and inclusive approaches into their modules.
Their focus is on supporting students to explore statistical principles in a low-stakes environment, a space where they can attempt, reflect, and try again without penalty. Rather than expecting students to leap from descriptive statistics straight into complex applied tests, concepts are introduced gradually and in digestible stages.
Students are encouraged to question data, explore variation, and develop conceptual understanding before they make formal decisions about statistical tests. This stepwise approach helps build the security students need to engage deeply with quantitative reasoning.
These inclusive strategies support a wide range of learners. International students benefit from explicit language support and structured examples. Students returning to education after a break value the opportunity to practise at their own pace. And across diverse cohorts, the reassurance of low-stakes practice reduces the sense that statistics is a hurdle separate from science.

The impact of digital tools
Digital tools such as Statistical Principles Smart Worksheets have supported these changes by providing spaces where students can pratice, receive instant feedback, and reflect without penalty. These interactive activities encourage experimentation and reinforce understanding through personalised immediate feedback, a vital feature for students who may struggle with confidence or who learn best through repetition.
When used alongside inclusive teaching strategies, these resources can help close confidence gaps across diverse cohorts. With LearnSci Analytics, educators can also identify patterns in cohort performance, spotting areas and questions where learners may be struggling and tailoring their support accordingly.
Creating conditions for confident data work
When statistics stop feeling like a hurdle, students begin engaging with data as a tool for exploration. Educators consistently report that when students are given space to practise, with clear scaffolding, repeated low stakes opportunities, and supportive feedback, their confidence grows.
At the University of Exeter, internal feedback from a recent postgraduate taught (PGT) cohort using genetics-focused Smart Worksheets showed:
4.4 / 5 for improved confidence
4.4 / 5 for improved statistical skills and performance
At LearnSci, we’re proud to lead that shift. Our Statistical Principles Smart Worksheets and LearnSci Analytics platform help educators provide meaningful, accessible practice that nurtures data confidence across disciplines. By combining inclusive pedagogy with interactive digital tools, universities are showing that statistics doesn’t have to be a source of fear; it can be a foundation for curiosity and growth.
