確率分布 これまで「分布」という言葉が何度も出てきたが、この「分布」とは確率分布のことを指している。ここでは具体的なさまざまな確率分布を紹介する。 まず確率分布の定義であるが、確率分布とは、確率変数の各々の値に対する、その生起しやすさをプロットしたものである。

Definition: Inferential statistics is a statistical method that deduces from a small but representative sample the characteristics of a bigger population.In other words, it allows the researcher to make assumptions about a wider group, using a smaller portion of that group as a guideline. It is used in salary, population, and many other similar statistics, where estimates are calculated using a sample.
After all, inferential statistics are based on the concept of using the values measured in a sample to estimate or infer the values that would be measured in a population.

With inferential statistics, you take data from samples and make generalizations about a population.. For example, you might stand in a mall and ask a sample of 100 people if they like shopping at Sears.

Inferential statistics can be contrasted with descriptive statistics. The second limitation of inferential statistics is related to the first one. Ultimately, there is always a degree of uncertainty in doing this.


Descriptive statistics describes data (for example, a chart or graph) and inferential statistics allows you to make predictions (“inferences”) from that data. Statistical inference is the process of using data analysis to deduce properties of an underlying distribution of probability. Inferential statistics is used when we have to generalize information about the available data.
