This course is the foundation stone of statistics, as its understanding will be helpful throughout the statistical analysis. We will learn different statistical parameters like central tendency, the measure of deviation, variance, standard deviation, moment, skewness and kurtosis, are use to describe a statistical variable completely and also the understanding of different frequency distribution curves, their skewness and kurtosis with easy to understand explanations and examples. We will also learn how to study inequalities in the distribution graphically and how to measure them through Lorenz curve and Ginni's index
At the end of my course, students will be able to...
Draw conclusions out of statistical data and graphs.
Will able to compare and draw conclusions based on statistical data using standard Deviation.
Able to draw Lorenz curve on excel and can calculate significant value for Lorenz curve using Ginni's index.
Understands the empirical relationship between different statistical parameters that are average, standard deviation etc.
Can calculate moment of variables.
Can use different coefficients based on moment to calculate skewness and kurtosis.
What will students need to know or do before starting this course?
Basic Microsoft Excel
Who should take this course?
Students pursuing courses in economics, statistics, management and biostatistics.
Professionals like Business analyst and Economist
Researchers like Ecologist, Bio-technologist etc.(having non- mathematical background)

I am a passionate academician and have earned my degree of Masters of Technology in Biotechnology. I worked as Assistant Professor in the department of biotechnology for 2 years and taught subjects like statistics, biochemistry, microbiology, immunology, biotechnology, genetics and instrumentation. I also worked for Transtutor's as an expert.
Biotechnology is all about techniques and their applications and to understand them it is important to read the lot of research papers, which contains a huge amount of statistical data and graphs. As an academician, I realised the difficulties faced by a student with non- mathematical background to interpret statistical data. Hence this encouraged me to make the course which starts from the basics of statistics .i.e. mean, median and mode.
My strength is to convey difficult ideas in a simple way and has used simple examples which make the concept easy to understand and apply.
This course will not only help non- mathematical background students or researchers but also help all those who want to make their career as an analyst or economist.
Let us, then, up and doing,
With a heart for any fate;
Still achieving, still pursuing,
Learn to labor and to wait.
