What are some examples of statistics to predict?
When polls are taken, they tend to predict the outcome of political elections.
What is the rationale of studying statistics?
There are very many things in life where the outcome is uncertain. Studying statistics gives you the tools to make sense of the information, validate the information and helps you to make rational decisions based on statistics.
Scientists use statistics to?
Find the likelihood of events whose outcomes include an element of uncertainty, or to find the measure of uncertainty in the outcome of events.
What is the meaning of the word likelihood?
In statistics, a likelihood function (often simply likelihood) is a function of a statistical model. The likelihood of a set parameter values, given outcomes x, is equal to the probability of those observed outcome.
Why are statistics always concerned with mass phenomenon and never a single observation?
Statistics deals with determination of enough data points to be able to predict future outcomes. A single observation is not enough to establish reality or predict the future outcome. If you flip a coin and it lands heads, is it enough to say that every time you flip a coin it will be heads? Of course not!
