Scatterplots are also known as scattergrams and scatter charts. As one variable increases, Round the number to the nearest hundredth. So it's a positive. Once you do that, determining the percentiles of the standard normal curve is straightforward. You can also use the data featured in this tutorial by clicking on 'Open This Data in Chart Studio' on the left-hand side. are more obvious than others. A normal probability plot of the residuals is a scatter plot with the theoretical percentiles of the normal distribution on the x-axis and the sample percentiles of the residuals on the y-axis, for example: Making statements based on opinion; back them up with references or personal experience. So, I could try to do a fancier curve that looks something like this, and this seems to fit There is a strong correlation between the two measures. the other variable decreases. Then choose the desired colorscale from the respective dropdown menu. (-7,45) Arcu felis bibendum ut tristique et egestas quis: Recall that the third condition the "N" condition of the linear regression model is that the error terms are normally distributed. are all over the place. and I might even be able to fit a curve that gets a For example, the median, which is just a special name for the 50th percentile, is the value so that 50%, or half, of your measurements, falls below the value. But, there is one extreme outlier (with a value larger than 4): Here's the corresponding normal probability plot of the residuals: This is a classic example of what a normal probability plot looks like when the residuals are normally distributed, but there is just one outlier.

A model of the plan for the A: a) The problem is that to determine the percentile value of a normal distribution, you need to know the mean \(\mu\) and the variance \(\sigma^2\). You could view that as an outlier. This question is weighted zero but it is required.
