In mathematics, a table is a set of numbers or information organized in rows and columns. It is used to present data in a structured and easy-to-read format. Tables are commonly used in various mathematical concepts, such as representing data, organizing information, and solving problems.

A table consists of the following components:

**Rows:**Horizontal lines of data.**Columns:**Vertical lines of data.**Header:**The top row of the table that typically contains titles for each column.**Cell:**Each individual box within the table where a row and column intersect.

There are different types of tables, including:

**Numeric Tables:**These tables contain numerical data.**Frequency Tables:**Used to organize and display the frequency of values in a data set.**Two-Way Tables:**Also known as contingency tables, used to display the relationship between two categorical variables.

Tables are commonly used in various mathematical concepts, such as:

**Data Representation:**Organizing and presenting collected data in a tabular format.**Functions:**Displaying values of a function for different inputs.**Probability:**Creating probability tables to represent outcomes of events.

Here are some key points to remember when working with tables:

- Understand the components of a table: rows, columns, headers, and cells.
- Practice creating and interpreting different types of tables, such as numeric, frequency, and two-way tables.
- Learn to use tables to represent and analyze data in various mathematical contexts.
- Understand how to calculate and interpret data presented in tables.
- Practice solving problems using information presented in tables.

Data Analysis and Probability (NCTM)

Select and use appropriate statistical methods to analyze data.

Discuss and understand the correspondence between data sets and their graphical representations, especially histograms, stem-and-leaf plots, box plots, and scatterplots.
