Data collection is sometimes performed without considering the effect poorly collected data has in the strength of statistical conclusions. When researchers properly design an experiment, they are ...

Statistics are an essential piece of scientific experimentation. Here, we discuss an almost 100 year old landmark experiment that separated a guessing game from a proven ability. In doing so, it ...

In science, the success of an experiment is often determined by a measure called “statistical significance.” A result is considered to be “significant” if the difference observed in the experiment ...

Explain why probability is important to statistics and data science. See the relationship between conditional and independent events in a statistical experiment. Calculate the expectation and variance ...

Let X1,X2,... be a sequence of i.i.d. random variables, $X_{i},F_{\theta},\theta \in \Theta $. Let N1 and N2 be two stopping rules. For a class of exponential ...
