A pair of instruments will always have a coefficient that lies between -1 to 1. A coefficient below zero indicates a negative correlation. When two instruments have a correlation of -1, these instruments have a perfectly inverse relationship. If instrument A moves up by $1, instrument B will...
Example for How to Interpret Scatter Plots: Negative Correlation The scatter plot below shows the number of absences and the grade point average of students at a certain school. Describe the relationship represented by the scatter plot. Step 1:Per the labels of the axes of the graph, the hori...
I use the example below in my post abouthow to interpret regression p-values and coefficients. The graph displays a regression model that assesses the relationship between height and weight. For this post, I modified the y-axis scale to illustrate the y-intercept, but the overall results haven...
After fitting a regression model,check the residual plotsfirst to be sure that you have unbiased estimates. After that, it’s time to interpret the statistical output. Linear regression analysis can produce a lot of results, which I’ll help you navigate. In this post, I cover interpreting ...
A problem with covariance as a statistical tool alone is that it is challenging to interpret. This leads us to Pearson’s correlation coefficient next. Pearson’s Correlation Named after Karl Pearson, The Pearson correlation coefficient can be used to summarize the strength of the linear relationshi...

Background|Enter Data|Analyze Data| Interpret Data |Report Data Correlations Box Take a look at the first box in your output file called Correlations. You will see your variable names in two rows. In this example, you can see the variable name ‘water’ in the first row and th...
Negative correlations occur naturally in many contexts. For instance, as the amount of snowfall increases, fewer drivers appear on the road. Or, as a cow gets older, her milk production drops. As you exercise more, you tend to lose weight. The more cats there are in a neighborhood is re...
How Do You Interpret a Coefficient of Determination? The coefficient of determination shows the level of correlation between one dependent and one independent variable. It's also called r2or r-squared. The value should be between 0.0 and 1.0. The closer it is to 0.0, the lesscorrelatedthe dep...
