Types of Statistics

Descriptive statistics: methods of collecting, organizing, summarizing, and presenting data in an informative way.
Descriptive statistics describes and summarizes a given variable, value, or data of social phenomena.
It presents the character and distribution of some measured phenomenon.
Inferential statistics: interpreting data, generalizing from a sample to a wider population, and testing hypotheses.

Descriptive Statistics

Example: calculating the most popular college major (mode) and average age (mean).
Descriptive statistics uses numerical and graphical tools to summarize and present data.

Inferential Statistics

Inferential statistics is used to make generalizations from a sample to a wider population.
It is used in testing hypotheses and deciding whether the data is consistent with the research prediction.

Definition of Statistics

Statistics is a branch of applied mathematics that involves the collection, description, analysis, and inference of conclusions from quantitative data.
It is the study of numbers used to represent various aspects of life, including numerical description, counting, ranking, measuring sizes, quantities, opinions, and feelings.
Statistics is the practice or science of collecting and analyzing numerical data in large quantities, especially for the purpose of inferring proportions in a whole from those in a representative sample.
