In this video we are gone talk about what inferential statistics does in 6 simple steps (Hypothesis, Population and Sample, Hypothesis Testing, p-Value, Statistical Significance, Errors). But, what is inferential statistics? Inferential statistics allows us to make conclusions or inferences about a population based on data from a sample.

![What is a Raincloud Plot? [Simply explained]](https://i.ytimg.com/vi/ituWaiJu3nI/mqdefault.jpg "What is a Raincloud Plot? [Simply explained]
A Raincloud Plot is a data visualization tool that provides a comprehensive view of a dataset by combining several plots into one figure. It essentially brings together the power of a box plot, violin plot, and a strip or swarm plot, making it easier to understand both the overall distribution and the raw data of a given variable or group.
But what are the components of a Raincloud Plot?
Cloud (Violin Plot):
The cloud in the Raincloud Plot is a rotated and horizontally aligned kernel density estimation (similar to a violin plot) that shows the distribution density of the data. It provides insights into the shape of the data distribution, highlighting areas of higher density.
Rain (Strip or Swarm Plot):
The rain consists of individual data points or raw data, represented as dots. This part of the plot shows each data point, giving a clear view of the raw data.
Boxplot:
Often theres a traditional box plot, showing the median and interquartile range.

What is a Pearson correlation? The Pearson correlation analyses the linear relationship between two variables. With the help of the Pearson correlation coefficient r which is between -1 and 1 we can determine:
How strong the correlation is
and in which direction the correlation goes.
