Statistical significance between 2 values
WebAug 28, 2024 · The p-value (also known as Alpha) is the probability that our Null Hypothesis is true. Obtaining a significant result simply means the p-value obtained by your statistical test was equal to or less than your alpha, which in most cases is 0.05. A p-value of 0.05 is a common standard used in many areas of research. WebSep 30, 2024 · Statistical Significance Formula The image below is the chi-squared formula for statistical significance: In the equation, Σ means sum, O = observed, actual values, E = expected values. When running the equation, you calculate everything after the Σ for each pair of values and then sum (add) them all up. 5. Calculate your expected values.
