Statistics has two meanings:
1. Statistics refers to numerical facts.
2. Statistics is a group of methods for planning studies and experiments, obtaining data, and then organizing, analyzing, presenting, interpreting, and drawing conclusions and making predictions based on the data.
Suppose we toss a coin 100 times
How many heads would you expect to get if the coin was fair?
If you got 55 heads, would you conclude that the coin was not fair?
If you got 95 heads, would you conclude that the coin was not fair?
If you got 75 heads, would you conclude that the coin was not fair?
We will study two main areas of Statistics:
Descriptive StatisticsMethods for organizing,displaying, and summarizingdata.
Inferential StatisticsMethods to make predictionsabout a population based on samples.
"Statistics: The only science that enables different experts
using the same figures to draw different conclusions."
~Evan Esar
