Easy p-values with an example
In this video, we will discuss p-values and how to interpret them- easily explained! We will go through p-values and what they mean with an example! You might have heard that a p-value lower than 0.05 or 0.01 is statistically significant... but what does that mean exactly?
And as always, you can find the full explanation at biostatsquid.com
Hope you like it!

    I have a question: Let's say I want to calculate the PCA of children's grades at school to know how it impacts the final grade average of each child. For that I have my sample, which would be all the children in a class, for example. Then I have the grades of those children in different subjects such as Math, History, Physical Education, etc. And I also have the average. Do I add the average as another variable to the PCA analysis? Or should I make a correlation, for example, between PC1 and the average and see the PCA loadings?

  • @苏秋羊

I have 2345 significantly differentially expressed genes, and when I try to plot all of the significant genes, I can see all of the gene names on the volcano plot. However, when I try to visualize merely 30 or 100 genes, the codes work correctly but I am unable to see them. Could you help provide me some advice on how to solve this issue? Thank you in advance.
