How to Interpret Regression Analysis Results: P-values and CoefficientsJim Frost
the better-fitted the regression line you’ll get. Here, the value of R Square represents an excellent fit as it is 0.94. It means that 94% variation in the dependent variable can be explained by the independent
In this post, I show how to interpret regression models that have significant independent variables but a low R-squared. To do this, I’ll compare regression models with low and high R-squared values so you can really grasp the similarities and differences and what it all means. Related pos...
Regression is a complex statistical technique that tries to predict the value of an outcome or dependent variable, such as annual income, economic output or student test scores, based on one or more predictor variables, such as years of experience, national unemployment rates or student course gra...

Regression analysis is one of the most powerful multivariate statistical technique as the user can interpret parameters the slope and the intercept of the functions that link with two or more variables in a given set of data. There are two types of regression multilinear regression and simple line...
It’s difficult to understand this situation using numbers alone. Research shows thatgraphs are essentialto correctly interpret regression analysis results. Comprehension is easier when you can see what is happening! With this in mind, I'll use fitted line plots. However, a 2...
In all linear regression models, the intercept has the same definition: the mean of the response, Y, when all predictors, all X = 0. But “when all X=0” has different implications, depending on the scale on which each X is measured and on which terms are included in the model. So...

This is true irrespective of whether the test involves comparisons of means, Odds Ratios (ORs), regression results or other types of statistical tests. As readers of research, it is important to understand the underlying principles of hypothesis testing, so that when faced with statistical results...
