1. Working with Basic Functions

Mastering basic functions is fundamental for any business analyst. These functions simplify calculations, enable data aggregation, and provide insights with minimal effort. Below are the key functions, their descriptions, and practical examples of usage:

SUM

Description: Calculates the total of a range of numbers.
Syntax:
=SUM(number1, [number2], ...)

Example:
Suppose you have sales data in cells A1 to A5:

A
100
200
150
250
300

Using the formula =SUM(A1:A5), the result is 1000. This is useful for quickly calculating total revenue, expenses, or other aggregated values.

---

AVERAGE

Description: Returns the mean value of a set of numbers.
Syntax:
=AVERAGE(number1, [number2], ...)

Example:
Using the same dataset (A1 to A5), the formula =AVERAGE(A1:A5) will return 200, which represents the average sales amount. Analysts can use this to identify trends or benchmark performance.

---

COUNT

Description: Counts the number of numeric entries in a range.
Syntax:
=COUNT(value1, [value2], ...)

Example:
If you use the formula =COUNT(A1:A5) on the dataset above, it will return 5, showing how many data points exist in the range. This is particularly useful for analyzing datasets with missing or invalid entries.

---

IF

Description: Performs conditional calculations based on a logical test.
Syntax:
=IF(logical_test, value_if_true, value_if_false)

Example:
Suppose you want to identify if sales in column A exceed 200. In cell B1, enter:
=IF(A1>200, "High", "Low")

For the dataset:

A	B
100	Low
200	Low
150	Low
250	High
300	High

This categorizes sales performance as “High” or “Low” based on the condition.

---

VLOOKUP

Description: Searches for a value in the first column of a range and returns a value in the same row from another column.
Syntax:
=VLOOKUP(lookup_value, table_array, col_index_num, [range_lookup])

Example:
Assume you have a product price list:

Product	Price
A	10
B	20
C	30

To find the price of Product B, use:
=VLOOKUP("B", A1:B3, 2, FALSE)

The formula returns 20, helping analysts quickly retrieve specific data points from larger datasets.

---

INDEX and MATCH

Description: A more flexible alternative to VLOOKUP for finding data.

• INDEX: Returns the value of a cell in a specific row and column.
• MATCH: Returns the relative position of a value in a range.

Syntax:

• =INDEX(array, row_num, [column_num])
• =MATCH(lookup_value, lookup_array, [match_type])

Example:
Using the same product list, to find the price of Product C:

1. =MATCH("C", A1:A3, 0) returns 3 (the row number).
2. =INDEX(B1:B3, 3) returns 30 (the price).

Combining them:
=INDEX(B1:B3, MATCH("C", A1:A3, 0))

This is especially useful when working with dynamic datasets where column order may change.

Sales	Target	Meets Both Conditions?
150	100
80	90
120	110

To check if sales exceed 100 and meet or exceed the target, use:
=AND(A1>100, A1>=B1)

Results:

Sales	Target	Meets Both Conditions?
150	100	TRUE
80	90	FALSE
120	110	TRUE

This function is ideal for validating multi-condition scenarios in data analysis.

---

OR

Description: Returns TRUE if at least one condition is true; otherwise, it returns FALSE.
