When conducting research or analyzing data, determining whether the results are statistically significant plays a vital role in drawing meaningful conclusions. The term “statistically significant” indicates that the findings are not due to chance and have an actual impact. In this guide, we will explore both formal and informal ways to express statistical significance. We will also provide you with useful tips, examples, and regional variations where necessary.

1. Formal Expressions of Statistical Significance
When communicating research outcomes in a formal setting or academic context, it is essential to use appropriate language. Here are some phrases commonly used to express statistical significance:
1.1. The Results are Statistically Significant
This straightforward phrase effectively conveys that the data, analysis, or experiment’s outcomes demonstrate a meaningful impact. It indicates that the results are unlikely to have occurred due to random chance alone.
The survey results are statistically significant, providing strong evidence to support our hypothesis.
1.2. We Observe a Significant Relationship
This expression is suitable when discussing the connection or association between variables in a study or experiment. It affirms that the observed relationship carries substantial weight and is not merely coincidental.
Our study reveals a significant relationship between X and Y, showing the influence of X on Y’s outcome.
1.3. The Findings Reach a High Level of Significance
This phrase highlights the strength of the findings in terms of significance. It suggests that the acquired results are highly reliable and reinforce the proposed hypothesis or research question.
After conducting multiple trials, we can confidently state that the results reach a high level of significance, supporting our initial assumptions.
2. Informal Ways to Convey Statistical Significance
In more casual or everyday conversations, you may need to discuss statistical significance without using formal academic language. Here are some alternative phrases that can be used in such situations:
2.1. The Results Are Meaningful
This phrase implies that the findings possess significance and provide valuable insights. It conveys a sense of importance without getting into technical details.
The data we gathered from the experiment are meaningful, supporting our prediction.
2.2. We Have Strong Evidence
This expression emphasizes the strength of the evidence or data collected, indicating that the results are not random and have a substantial impact.
Based on the extensive sample size and rigorous analysis, we have strong evidence to suggest that the observed effect is real.
2.3. There Is a Clear Pattern
When working with data that exhibits a noticeable trend or pattern, this phrase can be employed to imply statistical significance in a more informal manner.
The survey responses form a clear pattern, which strongly indicates a significant preference for product A over product B.
3. Important Tips for Expressing Statistical Significance
When discussing statistical significance, keep the following tips in mind:
- Use appropriate statistical tests: Ensure you employ the correct statistical methods for analysis to determine significance properly.
- Report relevant p-values: P-values quantify the level of significance, so be sure to mention them when appropriate.
- Context matters: Depending on the field and research objectives, the threshold for significance may vary. Consider the context when interpreting and expressing significance.
- Avoid overgeneralization: Be cautious not to make sweeping claims solely based on statistical significance. Strong conclusions require a holistic understanding of the research.
- Provide confidence intervals: Alongside significance, confidence intervals indicate the precision of estimates and help capture the uncertainty of the findings.
4. Examples of Statistical Significance Statements
Here are a few examples to illustrate phrases conveying statistical significance in different contexts:
4.1. Example in Biology:
Our study provides evidence of statistically significant differences in cell growth rates between Group A and Group B, with a p-value of 0.001.
4.2. Example in Psychology:
The experiment’s results demonstrate statistically significant improvements in anxiety levels for participants exposed to the new therapy (p < 0.05), supporting its effectiveness.
4.3. Example in Economics:
We find strong evidence of a significant positive correlation between inflation and unemployment rates, suggesting a direct relationship.
Conclusion
Effectively conveying statistical significance is crucial for presenting research or making data-driven decisions. By utilizing appropriate language and phrases, both formally and informally, you can clearly communicate the strength and impact of your findings. Remember to consider the context, use relevant statistical tests, and interpret results accurately. So, whether you’re discussing scientific findings or engaging in everyday conversations, understanding how to express statistical significance is an essential skill for anyone involved in research and analysis.
