What do you think about the astonishing result: 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + ... = -1/12 ?

Dear researchers: As counterintuitive as it can be, the infinite sum of all the integers : 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 ... to infinity can be understood as = -1/12 i.e. Sum(all...

How thick is the Al2O3 thin film layer grown on Aluminum due to environment exposure? What is its Growth Rate ?

Dear colleagues: When you have an Aluminum plate, and then, lets say you sand its surface with a sandpaper, you remove its native Al2O3 thin layer previously formed on the surface. Instantly,...

What is your perception on using visual analysis or quantitative approaches to evaluate data from single-case research designs (n of 1 trials)?

Results of single-case research designs (i.e., n-of-1 trials) are often evaluated by visually inspecting the time-series graph and computing quantitative indices. A question our research team is...

What test should I use to compare two or three means, if data is not normally distributed but sample size is > 30 in each group?

I personally feel this as a most confusing question. As per my understanding, if sample size is > 30, and sample is skewed, we can still use paramteric approach, as it will follow Z...
