In this video I explain the Log Rank Test. We will go through what the Log Rank Test is and how it is calculated. What is the Log Rank Test? The log rank test is used in survival time analysis and compares the distribution of time to occurrence of an event of two or more independent samples.

In this video we are gone talk about descriptive statistics and I will explain the four key components in a simple way. Descriptive statistics aims to describe and summarize a dataset in a meaningful way. It provides a simple overview of the main characteristics of data. But it is important to note, that descriptive statistics only describe the collected data without drawing conclusions about a larger population. To describe data descriptively, we look at the four key components:
Measures of Central Tendency, Measures of Dispersion, Frequency Tables and Charts

What is a hypothesis? How are hypotheses formulated? And what types of And what types of hypotheses are there?
A hypothesis is an assumption or conjecture about a relationship.
For example, your hypothesis might be:
Men earn more than women in Germany.
Our goal now is to test this hypothesis.
So we want to know whether to reject or retain the hypothesis.
But what is it about null and alternative hypotheses?
Two hypotheses are always formulated, that assert the opposite.
These are called the null and alternative hypotheses.
