About sorting and filteringEssentially, sorting and filtering are tools that let you organize your data. When you sort data, you are putting it in order. Filtering data lets you hide unimportant data and focus only on the data you're interested in.
Data cleaningOne reason for filtering data is to remove observations that may contain errors or are undesirable for analysis.
In signal processing, a filter is a device or process that removes some unwanted components or features from a signal. Filters are widely used in electronics and telecommunication, in radio, television, audio recording, radar, control systems, music synthesis, image processing, and computer graphics.

Data sorting is any process that involves arranging the data into some meaningful order to make it easier to understand, analyze or visualize. Data is typically sorted based on actual values, counts or percentages, in either ascending or descending order, but can also be sorted based on the variable value labels.
A sorting algorithm will put items in a list into an order, such as alphabetical or numerical order. Sorting a list of items can take a long time, especially if it is a large list. A computer program can be created to do this, making sorting a list of data much easier.
Sorting is the process of placing elements from a collection in some kind of order. For example, a list of words could be sorted alphabetically or by length. Like searching, the efficiency of a sorting algorithm is related to the number of items being processed.

Sorting a database means arranging the records in a specific way to make reported data more usable. You sort records by choosing a specific field(s) within a record by which to sort. For example, an alphabetical sort by the last name field will arrange text data in ascending alphabetical (A-Z) order.
The items are arranged from largest to smallest in order. What are steps you should take to make sorting and filtering easier? Arrange the header in a single row, add a blank row and column to separate the group of data, remove blank rows and columns from the group of data. What does Ctrl-A do?
