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 negative correlation, and the third example will deal with a situation in which there is no correlation...

1、Scatter plot with No Correlation In this type ofscatter plot, the data points are spread all over the graph randomly. Therefore, you cannot draw a straight line through them. As a result, it shows that there is no correlation between the variables. It is also known as 'Scatter Diagram...
Scatterplot MatricesWhen we have more than two variables and we want to find the correlation between one variable versus the remaining ones we use scatterplot matrix. We use pairs() function to create matrices of scatterplots.SyntaxThe basic syntax for creating scatterplot matrices in R is −...

Since we already inspected this data file (and set missing values) we can simply run correlations whours salary. and see that the correlation is 0.648, quite a strong linear relation. Some would leave it at. However, a scatterplot will show that there's way more to this relation. SPSS...
Beneath this syntax, we find all 6 unique scatterplots. Most of them show substantive correlations and all of them look plausible. However, do note that some plots -especially the first one- hint at some curvilinearity. We'll thoroughly investigate this in our second example....
By depicting data as a mass of points across two axes, scatterplots are effective in visualizing trends, correlations, and anomalies. But using them for large datasets often leads to overlapping dots that make themmore or less unreadable. ...
