What is Statistical Analysis?

Scientific rigor for business decisions

Statistical analysis applies mathematical methods to data to identify patterns, test hypotheses, and quantify uncertainty. Unlike descriptive analytics that simply reports what happened, statistical analysis helps you understand why things happen and predict what will happen with measured confidence.

Our statistical analysis services cover the full spectrum of analytical needs: descriptive statistics to summarize data, inferential statistics to draw conclusions about populations from samples, hypothesis testing to validate business assumptions, experimental design for A/B testing, time series analysis for forecasting, and advanced multivariate methods for complex relationships.

We bring scientific rigor to business decisions. Every analysis includes proper methodology selection, assumption validation, confidence intervals, and effect size estimation. You get not just an answer, but an understanding of how confident you can be in that answer and what factors might change it.

Why Choose DevSimplex for Statistical Analysis?

Research-grade methodology with business focus

We have completed over 150 statistical research projects and run more than 500 A/B tests, supporting publications in peer-reviewed journals and driving millions of dollars in optimized business decisions. Our team includes statisticians with advanced degrees and industry experience.

Our approach combines academic rigor with practical business sense. We do not just run tests - we design experiments that answer the right questions, select appropriate methodologies, validate assumptions, and interpret results in business context. We know that statistical significance is not the same as practical significance.

We are experienced across industries and domains. Whether you need clinical trial analysis for healthcare, experimental design for product optimization, time series forecasting for finance, or survey analysis for market research, we have done it before and know the specific considerations each domain requires.

We communicate results clearly. Statistical analysis is only valuable if stakeholders understand and act on the findings. We translate complex statistical concepts into clear recommendations, visualize uncertainty effectively, and provide the context needed for confident decision-making.

Requirements & Prerequisites

Understand what you need to get started and what we can help with

Required(3)

Research Question

Clear articulation of the question you want to answer or hypothesis you want to test.

Data Access

Access to relevant data with sufficient sample size for the analysis type required.

Context Documentation

Understanding of how data was collected, known limitations, and business context.

Recommended(1)

Domain Expertise

Access to subject matter experts who can validate findings and provide domain context.

Optional(1)

Historical Benchmarks

Previous analysis results or industry benchmarks for comparison and validation.

Common Challenges & Solutions

Understand the obstacles you might face and how we address them

Sample Size Limitations

Insufficient data leads to inconclusive results or false conclusions.

Our Solution

Power analysis and sample size planning before analysis, with appropriate methods for small samples when needed.

Multiple Testing Problems

Running many tests inflates false positive rates, leading to spurious findings.

Our Solution

Proper experimental design, pre-registration of hypotheses, and correction methods (Bonferroni, FDR) control error rates.

Assumption Violations

Using methods when assumptions are violated produces unreliable results.

Our Solution

Rigorous assumption testing with robust alternatives (non-parametric methods, bootstrapping) when needed.

Correlation vs Causation

Confusing correlation with causation leads to ineffective interventions.

Our Solution

Causal inference methods, experimental design when possible, and clear communication of what conclusions are supported.
