-*Sample

A sample is a subset of a population.

-*Variable

A variable is a characteristic of a population or sample.

-*Data

Data is a collection of observations on a variable.

Statistical methods are used to analyze data and draw conclusions about a population. Some of the most common statistical methods include:

• -*Descriptive statistics

  Descriptive statistics are used to summarize and describe data.

-*Inferential statistics

Inferential statistics are used to make inferences about a population based on a sample.

-*Regression analysis

Regression analysis is used to predict the value of one variable based on the values of other variables.

-*Analysis of variance

Analysis of variance is used to compare the means of two or more groups.

-*Nonparametric statistics

Nonparametric statistics are used when the assumptions of parametric statistics are not met.

Statistical concepts and methods are essential for understanding the world around us and for making informed decisions.

Data Visualization and Interpretation

Data visualization is the graphical representation of data. It is used to make data easier to understand and to identify patterns and trends. There are many different types of data visualizations, including:
