Key Concepts

Data Collection

Data collection is the process of gathering information from various sources through methods such as online searches, surveys, or experiments. It is fundamental in gathering accurate and relevant data that can be analyzed effectively, and it often involves validating and organizing the data to ensure its quality and reliability before further processing.

Bivariate Data

Bivariate data refers to the collection of observations on two different variables for each subject or case. It is used to explore the potential relationship between the two variables, often visualized using tables or plots, allowing analysts to investigate how changes in one variable may correlate with changes in the other.

Scatter Plot

A scatter plot is a graphical representation of bivariate data in which each point represents an observation with its coordinates determined by two variables. This visualization tool helps in identifying patterns, trends, clusters, and potential outliers, thereby providing insights into the relationship between the variables.

Correlation Analysis

Correlation analysis is the statistical method used to assess the strength and direction of the relationship between two quantitative variables. It quantifies how changes in one variable are associated with changes in another, offering a foundational approach to understanding patterns in data and informing further analysis or decision-making.
