Which data type allows field values to contain letter digits and other characters?
The data type that allows field values to contain letter digits and other characters is typically called a "string." Strings can store a sequence of characters, including letters, numbers, symbols, and spaces. They are commonly used in programming and databases to represent textual data.
What is string array?
A string array is an array whose contents are strings.An array is when you use a single variable names to store different data items. The data items are distinguished by a number (sometimes by more than one).A string is a data type used to store texts. It may contain letters, digits, or other symbols.A string array is an array whose contents are strings.An array is when you use a single variable names to store different data items.

Column Names.
How are significant digits related to calculations using measurements?
Significant digits, or significant figures, reflect the precision of a measurement and convey the reliability of the data. When performing calculations with measurements, the number of significant digits in the result should be determined by the measurement with the least number of significant digits. This practice ensures that the final answer accurately represents the precision of the input data, preventing false precision and maintaining the integrity of the calculations.
How is a check digit used as a validation check?
A check digit, typically the last digit of a number, can be computed from the other digits. For example, if you have an account number 1234, the bank might add a 5th digit of 0 because 1+2+3+4=10 and the low digit of 10 is zero. So they would tell you your account number is 12340.Then if you type it in by mistake as 12350 or 12347 or some such, a web page could immediately know it was wrong before looking it up in the database.If you typed in 33310 by mistake, it would think the check digit was correct -- so you can see it is good for saying what is probably wrong, but not what is RIGHT.Real check digits will detect swapping of two digits (which the sum above does not). Also, today a check digit is less important than it was in 1980 as it is quick to actually look it up and see if it is a valid account number without using a check digit at all.

What data does the computer record?
Computers record data in the form of "bits", Binary Digits.
What is the advantage data in a table over data presented in a paragraph?
number of digits that can be included
What device works with discrete data or digits?
analog
Can frequency distribution contain qualitative data?
frequency distribution contain qualitative data
What is the purpose of a check digit?
A check digit is a form of redundancy check used to verify the integrity of a set of data, such as a barcode or identification number. It is a single digit added to the end of a sequence that helps detect errors in data entry or transmission, ensuring that the information is accurate. By performing a specific calculation based on the other digits, the check digit can indicate whether the data has been entered correctly or if there are discrepancies that need to be addressed.
