Positive Correlation: The slope of the line drawn is positive, the values of x and y are both increasing. Negative Correlation: The slope of the line drawn is negative, the values of x increase and y decrease. N
A scatter plot with increasing values of both variables can be said to have a positive correlation. The scatter plot for the relationship between the time spent studying for an examination and the marks scored can be referred to as having a positive correlation. Scatter Plot for Negative Correla...
If there is no apparent rise or fall of the data points then there is no correlation. Let's use these steps and definitions to practice interpreting scatter plots by working through three examples. The first example will deal with a positive correlation, the second example will deal with a...
From the plot, we can see a generally tight positive correlation between a tree’s diameter and its height. We can also observe an outlier point, a tree that has a much larger diameter than the others. This tree appears fairly short for its girth, which might warrant further investigation....
When the correlation coefficient is positive, the bivariate variables have a positive correlation (one increases as the other increases too). Now that you know the bivariate data definition, how to plot it in a scatter plot and how its variables correlate, it is time to take a look into a...

Positive correlation depicts a rise, and it is seen on the diagram as data points slope upwards from the lower-left corner of the chart towards the upper-right. Negative correlation depicts a fall, and this is seen on the chart as data points slope downwards from the upper-left corner of...
This graph shows a positive correlation. What are scatter graphs? Scatter diagrams and outliers An outlier is a piece of data which does not fit with the rest of the data set. It can be recognised as a point by itself. For example, here is a scatter diagram with an outlier. Outliers ...
When the two sets of data are strongly linked together we say they have a High Correlation.The word Correlation is made of Co- (meaning "together"), and RelationCorrelation is Positive when the values increase together, and Correlation is Negative when one value decreases as the other ...
It's also possible to replace the scatter plots in the upper triangle with the correlation between each pair of variables. The scatter plot matrix in Figure 15 shows these customizations. The legend at the right has a heatmap for the correlations, with dark red indicating a strong positive ...
