Also available are data analysis tool-pack, pivot table and chart, solver, and user-defined formulas. Some of these functions can be used to perform data cleaning, web query, data visualization, and Analysis.

Each category serves a specific purpose and is essential for effective data analysis. Let’s now look at each category and the formulas you can use as a data analyst.

Basic Mathematical Functions

The mathematical functions in Excel, which let you carry out basic arithmetic operations on numerical data, are the most fundamental tools for data analysis. These functions serve as the foundation for more intricate calculations. Some of the commonly used mathematical functions for data analysis include:

SUM

The SUM function adds a range of numbers together.

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.

Statistical Functions

Statistical functions in Excel allow you to analyze data sets by providing measures of central tendency, variability, and more.

These functions are valuable for making data-driven decisions. Some of the commonly used statistical functions include:

AVERAGEIF

The AVERAGEIF function calculates the average of a range based on a specified condition.

Syntax: `=AVERAGEIF(range, criteria, [average_range])`

Example: `=AVERAGEIF(F2:F10, “>50”)` – This formula will calculate the average of values in the range F2 to F10 that is greater than 50.

MEDIAN

The MEDIAN function returns the middle value of a range of numbers.

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

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.
