If the distribution is not normal but the variables are continuous, what type of test should I use to test the relationship between the two variables?

Hello, thank you for your video. I am trying to find the relationship between Happiness (Ordinal variable with more than 5 categories) and Income (continuous variable). In this case, I am having trouble deciding if I should run Pearson correlation (by treating the happiness variable as continuous since it has more than 5 categories) or whether run a spearman's correlation? Also, while I tried to check the assumption for Pearson correlation (treating happiness as continuous), I found that Income is not normally distributed. And when I generated a scatterplot for these two variables, the result is not clear and somehow visually indicates no linear relationship. What should I Do???

Hi! What is the best way to plot a spearman correlation so that we clearly see the information that it is giving? I think it's not useful to plot a regression line as it depends on outliers, while the spearman correlation doesn't.

@remusarizona21783 жыл бұрын
Thanks for posting…however, it would be nice to know where the heck the ‘6’, a constant, comes from in the formula for Spearman, but not in formula in Pearson’s correlation? Why is it in the formula no matter what the other info is? This seems strange indeed! I’d love to know…Thanks.
@aishafaisal22492 жыл бұрын
what if your hypothesis originally states that there IS a negative relationship , then you get a rho value of -0.2612922 and p value of 0.01042 what does this mean because its not -0.9 something which would indicate a strong negative? is it telling me there is a negative relationship but just not that strong?
@StevenBradburn2 жыл бұрын
If that's the case then you can conclude that the is a significant correlation. The coefficient value just suggests the magnitude of the correlation between the variables. You can still have a significant test with a low correlation value. The clinical significance of this will vary depending on what field of science you are studying. Hope that makes sense

How does it calculate de p-value if on the spearman correlation the distribution is not normal ?
@yosuke198412 жыл бұрын
Does ranked variables need to be ordered set or semi ordered set is allowed ? I feel semi ordered is sufficient to be monotonic.

The example for "independence of observations" is misleading. The reason why you should not recruit the siblings to the experiment is because that goes against "random sample", which is a lot more difficult to avoid, so it is rather acceptable depends on the research question. Independence of observations mostly happen when the observations are made together in space or time, which should be taken into consideration in the experimental design. For example, checking the correlation between scores of two exams. If the two exams held back to back without any break. Then the result of second exam might be affected by fatigue level coming from the first exam (which turns the research question into how a person's fatigue level affects the result of second exam). This, however, can be avoided by placing a break in between the two exams and assuming that participant's fatigue level is more or less the same at the beginning of each exam.

what if i dont know what the perason correlation coefficient is, I cant understand a single part of the video, bad examples too, fitness pain correlation with spearman just because you named the variables instead of had numerical value to represent the information.

@theneveristsofficial17323 жыл бұрын
Why do you say that it's necessary to give the two variables ranks in order to perform the test and then when you talk about performing a spearmans correlation test you show the table without the rank order.
