![]() The "effect" goes on the y-axis because it is the dependent variable. In such a situation, the "cause" is the independent variable and therefore goes on the x-axis. The quickest way to identify which is which is to think about the cause-effect situation. Still, in general, you want to have the independent variable on the x-axis and the dependent one on the y-axis. As we said before, it's only significant for mathematical analysis of the data. The important things to master when learning how to read a scatter plot are variable choice, trend-spotting, and knowing the difference between correlation and causation. We can define this trend mathematically, but, as humans, we've evolved to be great at spotting patterns and relationships, sometimes too good, so we can do a lot without formal analysis. This noise is what we call any deviation from the underlying trend. Here we have 30 variables that don't seem to have any relationship, but, if we plot them, we can clearly see that we are dealing with a linear scatter plot with some noise. Let's look at some scatter plot examples and learn how to interpret the results from our scatter plot maker. We told you that we have your back at Omni, and we do. What information is it showing me?ĭo not worry. It is much more important to answer the questions that come after you make a scatter plot: what does that mean? I don't know how to read a scatter plot. You might be wondering if you should learn how to create a scatter plot by hand, and we would argue against it. Now, once you have inputted all your data, the scatter plot calculator shows you your cloud of data-points. Just remember that the scatter plot chart graph gets updated with every new input (you need to input the full x-y pair) but it only starts showing values after the second input, as it's not useful to create a scatter plot one piece of data, to be honest. Unless you want to analyze your data, the order you input the variables in doesn't really matter. You just need to take your data, decide which variable will be the X-variable and which one will be the Y-variable, and simply type the data points into the calculator's fields.
