Course Description
This course being the first course on Data Science and statistics aspirants. Starts with four lectures on essential concepts on probability which is a pre-requisite for any statistical or machine learning study
1. Explains the basic underlying concepts and definitions on probability involving, Chance experiments, Sample Space, Events, Likelihood
Two important theorems on probability namely
2. Conditional probability and
4. Bayes theorem
3. Various properties on Probability
The rest of the section focusses on the subjects pertaining to the title of this course
The second section focuses on
Probability distributions Starts with identifying the difference between a variable and a random variable. Explains discrete and continuous random variables and their characteristics. Move on to explain the need for the probability distributions. explains the basics, characteristics and definitions around the discrete probability distribution and continuous probability distributions. explains the graphical representations of probability distributions involving histograms and continuous functions Every aspect is illustrated with a simple case study to appreciate the details
The third section focusses on
two important discrete probability distributions namely Binomial distribution & Geometric distribution Explains - the conditions to be met for each of these experiments - derivation of mathematical functions that describe these distributions - mean and standard deviation (variance) for each of these distributions - applications of these distributions in certain real world using examples
The forth section explains
What is a Normal distribution? What is a standard Normal distribution ( z value / z curve )? How are probabilities evaluated for a standard Normal distribution and normal distribution? How to judge if a sample data is Normally distributed? What is a normal probability plot? How to transform data into a normal distribution when the sample is not? How to arrive at probabilities for a discrete probability distribution using normal approximations?
Goals
The essential concepts in probability form the most basic pre-requisite for carrying out any advanced statistical study or implementing machine learning algorithms. Understanding on random variables and their distributions are the next level pre-requisites in the above studies. This course covers right from the essential concepts in probability and cover in depth on random variables (discrete and continuous) and their corresponding important distributions namely normal, binomial and geometric distributions.
Prerequisites
None. Its the first course in the series of courses on essential statistics for data science

Hemakumar Kasala
Hi I am Hemakumar Kasala.
A passionate instructor who chose to train people in the area of Statistics, Data Science and Machine learning
A post graduate in Electrical Engg., from IIT Kharagpur India,
I have over 30 years of corporate experience working with multinationals like Robert Bosch, Philips and TPVision (subsidiary of TPV)
One of my primary responsibilities during my tenure with Philips/TPVision is to train people across sites worldwide on various technologies that we ventured into.
Currently I am on my own and my activities involve offering training courses on Statistics, Data science and machine learning.
Would love to engage with you and part my knowledge to the best of my understanding on the above subjects.
