Frequency Distribution Table
A frequency table is typically used for categorical or discrete numerical data. Examples include survey responses (e.g., yes/no answers), demographic categories (e.g., age groups, genders), or counts of occurrences (e.g., the number of pets owned by individuals). Continuous data can be categorized into intervals to create a frequency table, but it is not ideal for raw continuous data.
Intervals are used to organize data to simplify analysis and interpretation by grouping continuous data into manageable ranges. This helps highlight trends, patterns, and distributions within the data, making it easier to identify relationships and draw conclusions. Additionally, using intervals reduces the complexity of data presentation, allowing for clearer visual representation, such as histograms or frequency distributions. Overall, intervals facilitate more effective communication of information derived from large datasets.

A histogram is used when data is condensed into a frequency table. It displays the frequency of data within fixed intervals or bins, providing a visual representation of the distribution of the data.

A data table is used to organize and display information that are gathered.
The most important thing in creating intervals for a frequency distribution is that the intervals used must be non-overlapping and contain all of the possible observations. They are often equal intervals, but sometimes unequal ones are used. It all depends on the data.

A tablespace is a logical storage unit that contains segments, like tables and indexes, while a table is the structure within a database that stores data in rows and columns. Tables are stored within a tablespace, which provides the physical storage for the table's data.

A storage device
When data is in a table a form can be used to enter the data and it will add a new record to the table. This can be accessed from the Data menu or tabs.
