INTRODUCTION
 FORMULA
 A formula, in science, is a concise way of expressing
information symbolically as in a mathematical or
chemical formula.
 For example, determining the volume of a sphere requires a
significant amount of integral calculus or its geometrical
analogue, the method of exhaustion
 Having done this once, mathematicians can produce a
formula to describe the volume in terms of some other
parameter (the radius for example) as follows
V = 4/3 π r3
 A formula is a special type of equation that shows the
relationship between different variables

 Formulas can range from basic mathematical
operations - such as addition and subtraction - to
complex engineering and statistical calculations.
 A formula in a spreadsheet is an instruction to carry
out some activity.
 For example Tot = 5 + 7 + …+ 20
 A formula allows the spreadsheet to perform
automatic calculations based on values in other cells
and to display the result.
 FUNCTION
 Spreadsheet programs also contain a number of built
in formulas called functions.
 A function is a predefined formula that performs
calculations using specific values in a particular order.

 The function name tells Excel what calculation to
perform. The arguments are contained inside round
brackets.
 For example: = SUM()
 One of the key benefits of functions is that they can
save you time since you do not have to write the
formula yourself.
 For example, you could use
an Excel function called
STDEV to quickly find the
standard deviation of a range
of numbers.

FILTER & SORT
 Data Organization
When working on a worksheet with many rows
of data, it can be difficult to view and analyse the
data easily.
1. Filtering is a quick and easy way to find and work with
a subset of data in an Excel range.
2. Filters enable you to quickly find all the entries for a
particular item, e.g. an employee name or a product,
in a large worksheet.
3. Filters allow you to select just the data you need, and
to hide any data that is not relevant to your search.

4. Unlike sorting, filtering does not rearrange your data,
it simply hides the rows you don’t want. This will allow
you to then edit, format, chart and print your filtered
data as you wish.
 Preparing to filter
 Ensure the data in your worksheet is neat and tidy
and you will find filtering easy. The following steps are
useful to prepare data:
 Use headings. The top row of each column should
have a heading.
 Don’t mix the data. The data in a column should all
be the same type – don’t mix text and numbers.
 Don’t interrupt. Don’t have blank rows or columns.
Individual blank cells are OK.

 Filtering Steps
1. Click inside a table, and then choose Filter in the Sort
& Filter group of the Data tab (or press Ctrl+Shift+L)

2. Click the filter arrow beside the column heading for the
column you want to filter.
3. Excel displays a drop-down list, which includes one of
each unique entry from the selected column.
4. Remove the check mark from Select All (All items in
the list are deselected).
5. Select the check
box for the entry
you want to filter
and then click OK

 Data Sorting
 Sorting data is an integral part of data analysis. Data
can be sorted by text (A to Z or Z to A), numbers
(smallest to largest or largest to smallest), and dates
and times (oldest to newest and newest to oldest) in
one or more columns.
 Data can be sorted by a
custom list (such as
Large, Medium, and
Small) or by format,
including cell color, font
color, or icon set.
 Most sort operations are
column sorts, but you
can also sort by rows.

1. String Functions
1. CHAR
2. LEN
3. CONCATENATE
1. CHAR
 This function is used to return the character specified
by a number.
 All characters that are available for use on a
computer have been assigned a number.
Unfortunately, not all computers use the same
numbering system or code when numbering the
different characters.

 The syntax
= CHAR (Number)
 Number is a number between 1 and 255 specifying
which character you want. The character is from the
character set used by your computer.
 Windows computers use the ANSI code system. ANSI
is short for American National Standards Institute.
 The opposite of CHAR function is CODE function

2. LEN
 This function is used to count the number of
characters in a cell
 The syntax
=LEN(text)
Space between two characters is also
considered as characters

 CONCATENATE
 This function is used to join up to 255 text strings into
one text string
 The syntax
=CONCATENATE(Text1,Text2,Text3,…)
 The symbol & can be also used to joint several texts
into one text string. This function may be of great
importance to reorganize texts copied from PDF file

2. Numeric/Mathematical Functions
1. COUNT & COUNTA
2. COS
3. EXP
4. IF
5. SUMIF
6. SUMIFS
7. SUMSQ
8. FDIST
9. FINV

1. COUNT & COUNTA
 This function is used to count the number of cells that
contain numbers, and counts numbers within the list
of arguments.
Syntax
=COUNT(value1, [value2], ...) or COUNT(cell range)
 This is similar to the COUNTA function that is used to
count the number of cells that are not empty in a
range.
Syntax
=COUNTA(value1, [value2], ...) or COUNTA(cell
range)

2. COS
 This COS function is used to return the cosine of the
given angle.
Syntax
=COS(number)
 The number is the angle in radian unit. An angle in
degree is converted to radian by multiplying it with
PI()/180, or use the RADIANS function to convert the
angle to radians.
=COS(PI()*angle/180) or =COS(RADIANS(angle))

3. EXP
 This function is used to return e raised to the power of
number (ex). The constant e equals
2.71828182845904, the base of the natural logarithm.
Syntax
=EXP(number)
 Number is the exponent applied to the base e.

4. IF
 This function is used to return one value if a condition
specified evaluates to TRUE, and another value if that
condition evaluates to FALSE.
Syntax
=IF(logical_test, [value_if_true], [value_if_false])

5. SUMIF
 This This function is used to add the cells specified by
a given criteria.
Syntax
=SUMIF(range,criteria,sum_range)
 Range is the range of cells to be evaluated by
criteria.
 Criteria is the criteria in the form of a number,
expression, or text that defines which cells will be
added. For example, criteria can be expressed as 32,
"32", ">32", or "apples“.

 Sum_range are the actual cells to add if their
corresponding cells in range match criteria. If
sum_range is omitted, the cells in range are both
evaluated by criteria and added if they match criteria.

6. SUMIFS
 This function is used to add the cells in a range that
meet multiple criteria.
 The order of arguments differ between the
SUMIFS and SUMIF functions. In particular,
the sum_range argument is the first
argument in SUMIFS, but it is the third
argument in SUMIF.
Syntax
=SUMIFS(sum_range, criteria_range1, criteria1,
[criteria_range2,criteria2], …)

Jumlahkah hasil penjualan (C3:C16) jika itu adalah hasil penjulanan
jagung (A3:A16) di Malang (B3:B16)

8. FDIST
 This function is used to return the F probability
distribution, and to determine whether two data sets
have different degrees of diversity.
 For example, you can examine the test scores of men and
women entering high school and determine if the variability in
the females is different from that found in the males.
Syntax
=FDIST(x,degrees_freedom1,degrees_freedom2)
probability
 X is the value at which to evaluate the function.
 Degrees_freedom1 is the numerator degrees of
freedom.

 Degrees_freedom2 is the denominator degrees of
freedom.
9. FINV
 This function is used to get the inverse of the (right-
tailed) F probability distribution. If p = FDIST(x,...),
then FINV(p,...) = x.

 This function is still available at present, and the new
functions should be considered. For more information
about the new functions, see F.INV function and
F.INV.RT function.
Syntax
= FINV(probability,deg_freedom1,deg_freedom2)
 The FINV function syntax has the following
arguments:
 Probability Required. A probability associated with
the F cumulative distribution.
 Deg_freedom1 Required. The numerator degrees of
freedom.
 Deg_freedom2 Required. The denominator degrees
of freedom.
