**Syntax**: `=SUM(number1, [number2], …)`

Example: `=SUM(A2:A10)` – This formula will sum the values in cells A2 to A10.

#### AVERAGE

The AVERAGE function calculates the arithmetic mean of a range of numbers.

**Syntax**: `=AVERAGE(number1, [number2], …)`

**Example**: `=AVERAGE(B2:B10)` – This formula will calculate the average values in cells B2 to B10.

#### MIN

The MIN function returns the minimum value from a range of numbers.

**Syntax**: `=MIN(number1, [number2], …)`

**Example**: `=MIN(C2:C10)` – This formula will return the smallest value in cells C2 to C10.

#### MAX

The MAX function returns the maximum value from a range of numbers.

**Syntax**: `=MAX(number1, [number2], …)`

**Example**: =MAX(D2:D10) – This formula will return the largest value in cells D2 to D10.

#### COUNT

The COUNT function counts the number of cells that contain numbers within a given range.

**Syntax**: =COUNT(value1, [value2], …)

**Example**: =COUNT(E2:E10) – This formula will count the number of cells in the range E2 to E10 that contain numbers.

**Example**: `=MEDIAN(G2:G10)` – This formula will return the median value in cells G2 to G10.

#### MODE

The MODE function returns the most frequently occurring value in a range.

**Syntax**: `=MODE(number1, [number2], …)`

**Example**: `=MODE(H2:H10)` – This formula will return the mode value in cells H2 to H10.

#### STDEV

The STDEV function calculates the standard deviation of a sample.

**Syntax**: `=STDEV(number1, [number2], …)`

**Example**: `=STDEV(I2:I10)` – This formula will calculate the standard deviation of the values in cells I2 to I10.

#### VAR

The VAR function calculates the variance of a sample.

**Syntax**: `=VAR(number1, [number2], …)`

**Example**: `=VAR(J2:J10)` – This formula will calculate the variance of the values in cells J2 to J10.

### Lookup and Reference Functions

Excel’s lookup and reference functions let you get data based on specific criteria and search for particular numbers within a range. When generating dynamic reports and working with enormous datasets, these capabilities are quite helpful. Some of the commonly used lookup and reference functions for data analysis include:

#### VLOOKUP

The VLOOKUP function returns a value from the same row in a given column after searching for a value in the first column of a specified table range.

**Syntax**: `=VLOOKUP(lookup_value, table_array, col_index_num, [range_lookup])`

**Example**: `=VLOOKUP(K2, A2:B10, 2, FALSE)` – This formula will search for the value in cell K2 within the range A2:B10 and return the corresponding value from the second column.

#### HLOOKUP

In contrast to the VLOOKUP function, which searches the first row in a specified table range for a value, the HLOOKUP function returns a value from the same column in a specified row.

**Syntax**: `=HLOOKUP(lookup_value, table_array, row_index_num, [range_lookup])`

**Example**: `=HLOOKUP(K2, A2:D10, 3, FALSE)` – This formula will search for the value in cell K2 within the range A2:D10 and return the corresponding value from the third row.

#### INDEX

The INDEX function returns the value of a cell in a given range based on specified row and column numbers.

**Syntax**: `=INDEX(array, row_num, [column_num])`

**Example**: `=INDEX(A2:C10, 4, 2)` – This formula will return the value in the fourth row and second column of the range A2:C10.

#### MATCH

The MATCH function searches for a specified value in a given range and returns its position as a relative row or column number.

**Syntax**: `=MATCH(lookup_value, lookup_array, [match_type])`

**Example**: `=MATCH(K2, A2:A10, 0)` – This formula will search for the value in cell K2 within the range A2:A10 and return its relative position as a row number.
