A T-table is a statistical tool used to display data in a clear and organized manner. It consists of two columns: one for the values of a variable and another for their corresponding frequencies or counts. This format helps in visualizing the distribution of data and is commonly used in various fields, including education, business, and research. In addition to summarizing data, T-tables can also assist in performing statistical analyses, such as t-tests. These tests help determine if there are significant differences between groups. Overall, T-tables are essential for simplifying complex data and facilitating better decision-making.
