Please respond to this question. Thanks.

As it happens, there are real-life applications for interaction that we often come across. What is interesting to note is that it’s always beneficial to distinguish between the quantitative interactions with their qualitative counterparts. 

So, could you further describe what significance “qualitative” interactions would have in statistics? What about “quantitative” ones? How can you distinguish between the two types of interactions between variables R and S?

Thanks,
