Basics of Statistics – Hypothesis

Viewer Rating [Total: 1   Average: 5/5]Today, I want to discuss on a very important topic on inferential statistics area and that is “Hypothesis”. Hypothesis means a conclusion based on some evidence collected from data for a certain time. In statistics , we explain hypothesis in two ways: When we have something already defined, we shall put the … Read more Basics of Statistics – Hypothesis

Basics of Statistics – Continuous Probability Distribution

Viewer Rating [Total: 0   Average: 0/5]Let us start today’s topic on uniform probability distribution (I will discuss on continuous dist today). Now, the concept comes in two forms: discrete and continuous. If I toss a coin then there are two possible outcomes: Head and Tail. If I roll a die, then it always return a digit (1 … Read more Basics of Statistics – Continuous Probability Distribution

Basics of Statistics – Binomial Distribution

Viewer Rating [Total: 1   Average: 5/5]Today, I would like to extend my previous topic on discrete probability distribution with the concept of Binomial Distribution. A binomial distribution is a specific probability distribution. It is used to model the probability of obtaining one of two outcomes, a certain number of times k out of fixed number of trials N of … Read more Basics of Statistics – Binomial Distribution

Basics of Statistics – Discrete Variable Distribution

Viewer Rating [Total: 1   Average: 5/5]In today’s topic I want to explain how we plot the distribution of a random discrete variable. Key terms: expected mean, probability, variance and standard deviation. Let’s explain it by an example. For rolling a Die, let us assume a random variable X (x=1,2,3,4,5,6). The probability is P(x) =1/6. That is exactly … Read more Basics of Statistics – Discrete Variable Distribution

Basics of Statistics – Sample Vs Population Data

Viewer Rating [Total: 1   Average: 5/5]In statistics, a sample is a part of a population and a population is a whole; it’s every member of a group. All elements in a sample must also by definition be part of the population as it is defined. The sample should be representative of the population from which it is … Read more Basics of Statistics – Sample Vs Population Data

Multiverse and Multiple Dimensions

Viewer Rating [Total: 3   Average: 5/5]The Human mind can perceive only four dimensions. The first three being physical dimensions such as length, breadth and height, and the fourth being the Time dimension. That is why we can see, hear, feel and touch only those entities which exist in the three dimensional world. Our sensory organs control how … Read more Multiverse and Multiple Dimensions

The Alien Theory

Viewer Rating [Total: 4   Average: 5/5]Since time immemorial, humanity has been perplexed about the possibility of extra terrestrial life and visitors from outer space. There have been numerous reports of sightings of spaceships and natural phenomenon which did not have any logical explanation and which could not be attributed to any other event or source. Cave paintings … Read more The Alien Theory

What is a Black Hole?

Viewer Rating [Total: 3   Average: 5/5]A black hole is a region of space-time exhibiting such strong gravitational effects that no particle or electromagnetic radiation, such as light, can escape from inside it. The theory of general relativity predicts that a sufficiently compact mass can deform space-time to form a black hole. The boundary of the region from … Read more What is a Black Hole?
