Statistical Significance For Dummies
Do you want to understand the concept of statistical significance but have no idea where to start? If you're dealing with research and data analysis, statistical significance is an important concept to learn. This article will explain the basics of statistical significance for dummies, so even a beginner can easily understand.
What is Statistical Significance?
Statistical significance is the probability that a relationship between two or more variables is not caused by random chance. In other words, a statistically significant result is one that proves the relationship between two variables is not the result of random variation. Put simply, it's the probability that the observed relationship is real, and not just a fluke.
How To Calculate Statistical Significance?
To calculate the statistical significance of a relationship, you first need to choose a statistic to measure it. Generally, this is done using a statistical test such as Student's t-test or Pearson's chi-squared test, but there are many others. Once you've chosen your statistic, you can calculate the probability that the observed result was due to chance.
What Does a Statistically Significant Result Mean?
A statistically significant result indicates that the relationship between two variables is real and not due to random chance. It does not necessarily mean that the effect is large, only that it is not likely due to chance. This is important because it means that the relationship is likely to remain consistent even when other factors are taken into account.
Examples of Statistical Significance
Let's look at a few examples of statistical significance. Suppose you are conducting a study to determine whether or not a new drug is effective at reducing symptoms of a certain medical condition. You would use a statistical test to calculate the probability that the observed difference in symptoms is real and not due to chance. If the probability is low, it indicates that the drug is likely to be effective at reducing symptoms.
Conclusion
In conclusion, statistical significance is an important concept to understand when studying research and data analysis. It is the probability that a relationship between two or more variables is not caused by random chance, and it can be calculated using a variety of statistical tests. A statistically significant result indicates that the relationship between two variables is real and not due to random chance. Understanding statistical significance can help researchers draw more accurate conclusions from their data.
