How To Find Frequency

The FREQUENCY is an Excel statistical analysis function that allows you to calculate. How many times certain values (also expressed for groups) occur within a list. (Example: age brackets, quantities, economic values, etc.). In this article, we will give you a complete guide about how to find frequency?

To apply the FREQUENCY, it is necessary to have two information matrices. Once the Frequency of Occurrence of a range of values ​​is calculated, Excel returns a vertical array of numbers. How to Find Frequency analysis in Excel can be calculated using the FREQUENCY function, with a Pivot Table. And the additional data analysis tool that the program makes available.

With this tutorial, we will see how to calculate the Frequency through the Functions and a Pivot Table. Regarding the Data Analysis Tool, Frequency has already been discussed in the section. Excel Data Analysis Tool: Histogram (analyze the frequency)

How to Find FREQUENCY function

In descriptive statistics, FREQUENCY is a calculation. That concerns the analysis of periodic phenomena or repetitive processes and verifies how certain values ​​occur within a data range.

Syntax of the FREQUENCY function

= FREQUENCY (data_array; class_array)

in which:

  • data_array is the set of values ​​whose Frequency is to be calculated.
  • class_array is the reference to the range by which you want to group values.

Definitions of: Absolute Frequency; Relative

The absolute frequency is the number of times an event occurs. The relative frequency is the result of the absolute frequency divided by the elements’ total to be analyzed. The absolute cumulative frequency is equal to the sum of the absolute frequency of the value and those that eventually precede it. Also, in this case, the data can be decentralized.

The absolute Cumulative FREQUENCY

Calculation of the absolute cumulative frequency. How many people are 31 years old will be calculated in the first cell. And then in the second, how many are (31 + 32) then (31 + 32 + 33) until reaching the general total in the last row.

In the example, the formula setting in cell G3 would be = FREQUENCY ($ C $ 3: $ C $ 16; E3). Using the absolute reference to indicate the data matrix allows you to drag the Function into the underlying cells.

The relative cumulative FREQUENCY

To calculate the Absolute Cumulative Frequency data percentage, divide each value obtained by the values’ total. And then format it as a percentage.To count exactly how many values ​​are present in the data matrix, the COUNT NUMBERS= FREQUENCY ($ C $ 3: $ C $ 16; E3) / COUNT NUMBERS ($ C $ 3: $ C $ 16) function is used.

How to Find FREQUENCY: Absolute

To calculate the absolute frequency, it is necessary to use the matrix formulas. In-depth analysis. The MATRIX formulas. Matrix Formulas are defined as those formulas whose result does not fit into a single cell. They must still be inserted in several contiguous cells (previously selected) when matrix formulas are inserted into the Excel sheet. They are automatically enclosed in curly brackets {} To insert a matrix formula in place of the enter command, type CTRL + SHIFT + ENTER.

In the example proposed, to insert a matrix formula, you must:

(a) Select the range of cells G3: G8

(b) Enter the function = FREQUENCY (C3: C6; E3: E8) in the formula bar without deselecting the area G3: G8

(c) Press CTRL + SHIFT + ENTER

the result of the insertion will be that the function will be entered in all cells: {= FREQUENCY (C3: C16; E3: E8)}

In this case, it is a question of decentralizing the result by dividing every single result by the total. As for the relative cumulative frequency, it is possible to count the total data to divide. The absolute frequency through the COUNT function. The result must be formatted as a percentage.

Calculate Absolute, Relative and Cumulative FREQUENCY

In version 365, a series of new features and functions have been added about matrices. Dynamic arrays have been introduced, i.e., functions that return the result, not in a single cell (the one that contains the formula), but are also distributed in adjacent cells (this characteristic is defined: spilling).

When inserting the Function, unlike the previous versions, not only is it no longer necessary to select the data area in which the result is to be returned in the form of an array, but it is not even necessary to insert the Function with the button combination: Ctrl + Shift + Enter. Consider the table below on which you want to calculate the Age Frequency relative to a certain number of employees.

In the case of the Absolute FREQUENCY calculation, there is no longer the need to select the entire E2: E7 data area! Just go directly to cell E2 and enter the Function: = FREQUENCY (B2: B17; D2: D7) and press enter. The spilling (data expansion) will calculate the absolute frequency data in correspondence with the classes, row by row. Once the Function has been inserted, if you click in cell E2, it is possible to enter the Function modification. As far as the data percentage is concerned, there is nothing different from the previous setting. Directly in cell E2 it is possible to enter the Function: = FREQUENCY (B2: B17; D2: D7) / COUNT. NUMBERS (B2: B17) also, in this case, just press ENTER to obtain the dynamic matrix that expands in cells E2: E7

Absolute Frequency calculation example with a Pivot table

Pivot Tables are the most powerful data analysis tool that Excel offers. Let’s analyze, step by step, creating an Absolute Frequency calculation with a Pivot table. So this section does not cover the meaning and explanation of how Pivot Tables work. For these contents, please refer to the numerous sections on this site. EXCEL general menu section 14: Pivot tables As an example, we consider a table of about 150 rows relating to four sellers’ sales operations.

Specifically, we want to calculate How to Find Frequency relative to how many invoices are issued in certain amount classes, or how many invoices have been issued up to 1000 euros; from 1001 to 2000 euros; from 2001 to 3000.

  1. Insert the Pivot Table into the Excel Worksheet
  2. Place the invoice field in the Rows item and the Values item in the Pivot Table Fields tool. The result will be the creation of a long table of two columns for each type of amount. The first column is a label; the second column reports or any sum (if there are more equal amounts) the invoices.
  3. Right-click on any label (first column of the Pivot Table).
  4. In the shortcut menu, select the Group … item, which opens the dialogue box of the same name.
  5. In the Group dialogue box, you have to create the classes you want to calculate the Frequency. So in the Group window, Excel initially proposes Starting from the lowest value present in the archive (110).

The procedure for using the FREQUENCY function

We must have all registered athletes’ age column in the same Excel sheet and the categories table.

  • Place the mouse on the right of the first row and column to insert the frequencies.
  • Keeping the mouse pressed, we select the column where we want to insert the number of frequencies; release the left mouse button at the end of the selection.
  • Click in the formula bar and write =FREQUENZA (after inserting the parenthesis, EXCEL proposes the formula FREQUENCY with data matrix in bold;
  • We have to insert in the formula in matrix data the column where the data is.
  • with the mouse go to the first cell where the data are and holding down the left mouse button select all the data;
  • release the mouse button and click in the formula bar by inserting an; after the range, you see selected. At this point, it becomes bold in the formula matrix classes;
  • Position the mouse in the class column and, keeping the left mouse button pressed, select all the class data;
  • Return to the formula bar and close the parenthesis, and press at the same time. ctrl + music + INVIO
  • At this point, you will see the number of frequencies (the number of subscribers in our example) next to each category.

We have prepared the example for your tutorial on an EXCEL file that you can freely download.

To give you concrete examples, on a Samsung smartphone, open the numeric keypad and type the code * # 0011 # to display all the relevant information on the smartphone’s frequency/network on the screen. So you don’t have to call this “number,” enter it on the keypad.

As for Huawei devices, however, usually, open the numeric keypad and type the code * # * # 232338 # * # *. On the iPhone, the code to enter is * 3001 # 12345 # *: you may have to press the UMTS Cell Environment item to access information relating to the data network. For other manufacturers, such as OPPO, the code might be * # 0 * #. However, these codes may not work on all models, as various manufacturers decide them.

Some screens may not contain frequency/band data but only a code called UARFCN. To do so, connect to the CellMapper site. And press the Calculate button: in this way, you will get the frequency at which your device is connected.

How to find the frequencies on my mobile via applications

In addition to Service Mode, several other applications allow you to understand at which frequency/network your mobile phone is connected. Below you will find the solutions of this type that I believe to be more valid.

There will also be the EARFCN code, which allows you to calculate the frequencies used. I have already explained to you how to use it. So this data in the chapter is dedicated to CellMapper (the procedure to follow).

Final remarks: How To Find Frequency

In this article, although a bit long, various ways of calculating FREQUENCY have been considered. When setting up the functions, it is essential to consider the Excel version you are working on. Certainly, in the Excel Microsft365 version, the dynamic matrices greatly simplify the application of some functions. Such as the FREQUENCY function.

Another opportunity that Excel makes available for calculating the frequency is the Analysis tool. (Datasheet – Add-on). Using the Data Analysis Tool to calculate Frequency has been specifically covered in the section: Excel Data Analysis Tool: Histogram (analyzing frequency).
