column is the first or last cell reference in a formula, the formula will not
automatically adjust. If the deleted row or column is the first or last cell
reference in a formula, the formula will automatically adjust the same as if
inserted within a range.
B. A function is an expression that performs common calculations and returns a
single value. Functions make a formula shorter and reduce the possibility of
errors. Excel functions provide one word access to a series of operations. Many
functions are built-in to Excel.
1. The most commonly used functions include SUM, AVERAGE, MIN, MAX, IF,
and ROUND.
a. SUM is a function in Excel that adds all the numbers in cells. When
creating programming functions, separate non-adjacent cells with commas:
=SUM (D4, E5, F8). Use a colon (:) to indicate adjacent cells or a range:
=SUM (G1:G5). Within the parentheses, list the first cell reference followed
by a colon and then the last cell reference. For example, (G1:G5) would
include cells G1, G2, G3, G4, and G5.
b. AVERAGE is a built-in function in Excel that calculates the average of a
group of numbers.
c. MIN is a function that finds the smallest number in a set of values.
d. MAX is a function that finds the largest number in a set of values.
e. IF is a function that is used to return one value if a condition is true and
another value if it is false. For example, if sales total more than $3,000
then return a “Yes” for Bonus, otherwise, return a “No” for Bonus. The IF
function is used often to analyze data by evaluating specific conditions.
f. ROUND is a function in Excel that rounds a number to a specified number
of digits. The ROUND function rounds up or down. 1, 2, 3 and 4 get
rounded down. 5, 6, 7, 8 and 9 get rounded up. For example, if the
number 543.678 is located in cell A1 and the user wishes the number to
be rounded to no decimal places, the formula would be =ROUND(A1, 0)
and the formatted response is 544, with no decimal places. If however, the
user wishes the number to be rounded to one decimal place, the formula is
=ROUND(A1, 1) and the response is formatted as 543.7.
2. Arguments are the values that functions use to perform calculations. Func
-
tions (built-in formulas) require data, i.e., arguments, to be entered, in order to
return a result. A function's syntax is the layout of a function, including the
function's name, parenthesis, comma separators, and its arguments. The argu
-
ments are always surrounded by parentheses and individual arguments are
separated by commas. A simple example is the SUM function. The syntax for
this function is: SUM (Number1, Number2, ... Number255). The arguments for
this function are: Number1, Number2, ... Number255.
Teaching Strategy:
Many techniques can be used to help students master this
objective. Use VM–D to illustrate Order of Operations. Use VM–E to review basic
formula use guidelines. Use VM–F to illustrate using functions in a formula. Use VM–G
to review reasons for formula error messages. Use VM–H to illustrate how formulas are
