A relational database stores data in tables that consist of rows and columns. Each table represents a specific entity, with rows corresponding to individual records and columns corresponding to attributes of those records. This structure allows for efficient organization, retrieval, and manipulation of data using structured query language (SQL). Examples of relational databases include MySQL, PostgreSQL, and Oracle Database.

Qualitative data is information that can not be measured, such as the colour of your eyes. Qualitative data descriobes
Yes. Conditional distribution applies to fractions of rows/columns. Marginal distribution applies to the totals for each row/column
Natural prisms are geological formations that consist of columns or shapes created by the crystallization of minerals, often seen in volcanic rocks like basalt. These formations occur when lava cools and contracts, leading to the development of polygonal, columnar structures that resemble prisms. An iconic example is the Giant's Causeway in Northern Ireland, where thousands of hexagonal basalt columns are formed. Natural prisms can also occur in other contexts, such as ice formations in glaciers or certain types of sedimentary rocks.
Databases consist of rows and columns. Each piece of information is entered into a row, which creates a "record."
No. A spreadsheet grid is made of rows and columns, not diagonals.
A relational database.
Yes. Tables in general are made up of rows and columns. If it is a database table it can be said to be made up of records which are rows and fields which are columns.
A table can have only one primary key, which uniquely identifies each record within that table. However, this primary key can consist of multiple columns, known as a composite primary key. The primary key ensures that no two rows have the same values in the specified key columns.
A table consists of rows and columns where data is organized in a structured format. Each row represents a record or entry, while each column represents a specific attribute or field. Tables are commonly used in databases and spreadsheets to store, manage, and analyze information.

Relational database stores data in tables that consist of rows and columns. Each row represents a record and each column represents a field within that record. Relationships between tables are established through keys.
A graph is used for graphing lines and points. A graph consist of rows columns and units.
multiple-choice questions
Yes, tables are commonly used to organize and present data in a structured form. They typically consist of rows and columns where each intersection represents a piece of data. Tables are helpful for easily comparing and analyzing information.
Class is a higher taxon than order in the hierarchy of biological classification. Classes consist of multiple orders, which in turn consist of multiple families, genera, and species.
