Statistics is about data: analysing data, making inference based on data and making predictions about the future based on the data.
Averages and Chebyshev's inequality
In this video you will learn about independent and identically distributed sequences of RVs and Chebyshevs inequality.
Graphical representation of data
In this video you will learn three graphical tools, which enable you to structure data easily: histograms, kernel density estimate and empirical distribution functions.
Numerical representation of data
In this video you will learn commonly used numerical summaries to find the centre or the spread of one-dimensional data.
Unbiased Estimators
In this video estimators are explained. You will learn about good and bad choices for an estimator and about unbiased estimators.
Maximum Likelihood Principle
In this video you will learn about the maximum likelihood principle with an example.
Confidence intervals
In this video you will learn about confidence intervals with help of some examples. You will also learn how you can interpret confidence intervals and how to calculate them.
Testing hypotheses
In this video you will learn about hypotheses testing. You will learn how to formulate a good null hypothesis and an alternate hypothesis and you will be made aware of the possible errors you can make.
The t-test
In this video you will learn about the t-test. You will also see an example of the t-test.
