Another very important concept in Statistics is ‘Normal Distribution’. Remember that a distribution being ‘normal’ means it is symmetrical with respect to the mean. However, this post does not intend to explain the mathematics behind a normal distribution (your teachers, tutors, and textbooks are there for that!), but to nonetheless answer a…

Correlation does not imply causation!

A very important concept in Statistics is the idea of correlation: we observe the behaviour or trend of two different variables (one independent, one dependent) and aim to decipher whether there is a mutual connection or common pattern between both. However, it is equally important to understand that the fact that two variables are correlated…

Reply to Limits and continuity

Hi Marta! Yes sure, here’s an explanation along with some examples to help you grasp these concepts:

Limits: In calculus, limits are used to study the behavior of functions as the input (x-values) approaches a specific value or as it tends to infinity. The limit of a function represents the value that the function approaches as the input…
