# The COUNT Function in Excel

The COUNT function is a powerful tool in Microsoft Excel that enables users to count the number of cells within a range that contains numerical values. It is particularly useful when dealing with large datasets or when you want to quickly determine the number of entries that meet specific criteria. In this lecture, we will explore the syntax of the COUNT function and provide examples using demo data.

## Syntax: The syntax for the COUNT function is as follows:

=COUNT(value1, [value2], …)

The COUNT function can accept one or more arguments, separated by commas. Each argument represents a range or value that you want to count.

## Examples:

Example 1:
Let’s consider a simple example where we have a list of students and their respective test scores. We want to count the number of students who scored above 80.

| A | B |
|——–|———|
| Name | Score |
| John | 75 |
| Sara | 92 |
| Mark | 81 |
| Emma | 78 |
| David | 86 |

## COUNT

COUNT(value1, value2, …)

• value1, value2, …: These are the values or ranges that you want to count. You can include up to 255 arguments, which can be individual cells, cell references, or ranges separated by commas.

Note: The COUNT function ignores any text or empty cells within the specified range. It only considers cells that contain numbers or dates.

COUNT(A2:B6)

This formula counts the number of cells within the range A2:B6 that contain numeric values.

It returns the value 5 which is the number of numerical values in the range.

## COUNTIF

To count the number of students who scored above 80, we can use the COUNT function as follows:

=COUNTIF(B2:B6, “>80”)

Explanation:
– B2:B6: This represents the range of cells containing the scores.
– “>80”: This is the criteria we want to apply, i.e., scores greater than 80.

The COUNTIF function counts the number of cells within the specified range (B2:B6) that meet the given criteria (>80).

Result: The COUNTIF function will return the value 3 since there are three students who scored above 80.

Example 2:

## COUNTA

Now, let’s consider a scenario where we have a dataset with missing values represented by blank cells. We want to count the number of non-blank cells in a given range.

| A | B |
|——–|———|
| Name | Score |
| John | 75 |
| Sara | |
| Mark | 81 |
| Emma | |
| David | 86 |

To count the number of non-blank cells in the range B2:B6, we can use the COUNTA function as follows:

=COUNTA(B2:B6)

Explanation:
– B2:B6: This represents the range of cells for which we want to count the non-blank cells.

The COUNTA function counts the number of non-blank cells within the specified range (B2:B6).

Result: The COUNT function will return the value 3since there are three non-blank cells in the range.

# Uncovering Patterns: Exploratory Data Analysis in Action

In the world of data science, exploratory data analysis (EDA) is a critical first step in any data analysis project. EDA is the process of inspecting, cleaning, and exploring data with the goal of discovering patterns and trends. By understanding the data, analysts can better ask questions, build models, and make predictions.

There are many different techniques that can be used for EDA, but some of the most common include:

Visualization: Creating charts and graphs to visualize the data can help to identify patterns and trends that may not be obvious from looking at the raw data.

Statistical analysis: Using statistical tests to measure the relationships between different variables can help to identify significant patterns.

Data mining: Using data mining algorithms to identify patterns and trends in large datasets can be helpful when the data is too complex to analyse manually.

## Uncovering patterns : Exploratory data analytics in action

EDA is an iterative process, meaning that it is often necessary to repeat the steps of inspection, cleaning, and exploration as new insights are gained. By continually exploring the data, analysts can uncover hidden patterns and trends that can lead to valuable insights.

Here are some examples of how EDA has been used to uncover patterns in data:

• A marketing analyst used EDA to identify that a particular product was being purchased more often by customers who lived in urban areas. This information could be used to target marketing campaigns more effectively.
• A financial analyst used EDA to identify that the stock price of a particular company was correlated with the price of oil. This information could be used to make predictions about the future performance of the stock.
• A healthcare researcher used EDA to identify that patients who were prescribed a particular medication were more likely to experience certain side effects. This information could be used to improve the safety of the medication.

These are just a few examples of how EDA can be used to uncover patterns in data. By understanding the data, analysts can make better decisions and improve the outcomes of their projects.

If you are interested in learning more about EDA, there are many resources available online and in libraries. There are also many data science courses that offer instruction on EDA. With a little effort, you can learn how to use EDA to uncover patterns in your own data. At Data Analytics Training and Advisory Services we train you to master the tools that you require to perform EDA.

# 10 Excel Functions You Must Know

10 Microsoft Excel functions you must know:

(1) XLOOKUP

(2) Wildcards

(3) Sparklines

(4) Filter

(5) Pivot Tables

(6) IF

(7) SUMIFS

(8) COUNTIFS

(9) Transpose

(10) TRIM

## (1) XLOOKUP:

XLookup is an upgrade compared to VLOOKUP or Index & Match.

Use the XLOOKUP function to find things in a table or range by row.

Formula: =XLOOKUP (lookup value, lookup array, return array)

## (2) Wildcards:

A wildcard is a special character that allows you to perform partial matches in your Excel formulas. Excel has three wildcards: • asterisk “*” • question mark “?” • tilde “~”

## (3) Sparklines:

Sparklines allow you to insert mini graphs inside a cell to provide a visual representation of data. Use sparklines to show trends or patterns in data. On the ‘Insert tab’, click ‘Sparklines’

## (4) Filter:

The FILTER function allows you to filter data based on a query. For example, you can filter a column to show a specific product or date.

You can also sort in ascending or descending order.

The shortcut for this function is CTRL + SHFT + L

## 5) Pivot Tables:

A powerful tool to calculate, summarize & analyze data, which allows you to compare or find patterns & trends in data. To access this function, go to “Insert” in the Menu bar, and then select “Pivot Table”

## (6) IF:

The IF function makes logical comparisons & tells you when certain conditions are met.

For example, a logical comparison would be to return the word “Pass” if a score is >70, and if not, it will say “Fail” An example of this formula would be =IF(C5>70,”Pass”,”Fail”)

## (7) SUMIFS:

SUMIFS sum the values in a range that meet multiple criteria.

For example, use it if you want the sum of two criteria, for example, Apples from Pete. The formula is SUMIFS (sum_range, criteria_range1, criteria1, [criteria_range2, criteria2], …)

## (8) COUNTIFS:

CountIf counts the number of times a criteria is met. For example, it counts the number of times that both (1) apples and (2) price > \$10, are mentioned.

## (9) Transpose:

This will transform items in rows, to instead be shown in columns or vice versa.
To transpose a column to a row: • Select the data in the column • Select the cell you want the row to start • Right click, choose to paste special, select transpose

## (10) TRIM:

TRIM removes the extra spaces in data.
TRIM can be useful in removing irregular spacing from imported data =TRIM()

## 7 tools every Excel user must know

7 tools every Excel user must know were selected and presented by experts to help you get more out of excel.  7 tools which are set to improve your productivity and make you love excel more and more.

## 1. Slicers

Being able to quickly drill down into data is critical when analyzing. Instead of applying filters manually, add slicers to the data by navigating to the Insert tab > Slicers > select what you want to filter the data by and hit OK. Now just click any button to filter!

## 2. Power Query

Importing data into Excel never is as easy as it seems. Luckily, Power Query is here to fix that. Power Query imports data from various sources into Excel. So instead of copying data from the web, go to Data > From Web > enter URL > select the table and hit load.

## 3. Data types

Say goodbye to google searching and hello to data types. Data types pull in real-time data directly into your workbook. To create data types, select the data > Data tab > Select the data category. Now, you can select the data attributes you want to pull into Excel.

## 4. Named Ranges

Naming data will not only make your life easier when writing formulas but also make your formulas easier to understand. To name data, select the data > press CTRL SHIFT F3 > check where the headers are and press OK. Now you can reference the data by its name!

## 5. Custom Lists

If you enter recurring lists repeatedly, this one’s for you. You can create a custom list that Excel will recognize and autofill for you. Go to File > Options > Advanced > Edit Custom Lists > Import List > OK. Now, enter any value and fill with the fill handle.

7. Sparklines

Stay on top of (Excel) trends with sparklines. A sparkline is a mini line chart that visually represents data trends. To insert them, press ALT N SL > select the data range you want to visualize and hit okay. Lastly, fill the sparklines down using the fill handle.

# Jobs where Excel skills will pay you handsomely

Jobs where Excel skills will pay you handsomely are probably the main reason why you should master Excel. The basic spreadsheet may hold the secret to the profession you want, whether you are currently an Excel pro or still have a ways to go. The demand for basic computer abilities in middle-skill professions has significantly increased over the past two years, according to 27 million job advertisements on various recruitment portals. This includes desirable skills for employers like word processing and of course, mastery of spreadsheets.

According to a survey by Capital One and Burning Glass Technologies, having these abilities is not only necessary for the vast majority (82%) of middle-skill professions, but it also opens the door for people without university degrees to high-paying careers.

Excel’s interface may appear straightforward and familiar to everyone, but behind are strength and sophistication that, 30 years after its introduction, are still unsurpassed. Because of this, anyone who wishes to advance in their career should have solid Excel skills. In fact, a sizable percentage of occupations require Excel, according to thousands of job advertisements. This extensive selection may contain the ideal option for you:

## Accountants and auditors

These people may have been in mind when Excel was created, with the traditional accounting ledger serving as the basis for spreadsheets. To keep businesses profitable, these experts produce and carefully examine cash flows, income statements, balance sheets, and tax reports. Without a college degree, getting this job would be next to impossible, but having solid Excel accounting abilities and certifications can put you in a better position for leadership positions and promotions.

## Administrative assistants, office clerks, information staff

Business operations are facilitated by administrative assistants, who include secretaries and other general office clerks. They set up appointments, handle records, arrange paperwork, create reports, and assist workers, clients, and guests. They frequently use spreadsheet programs like Excel and word processing applications.

## Business, management, and market analysts

Business analysts can use a potent Excel function called PowerPivot to extract more insightful information from vast amounts of data and this tool was made specifically for them. These experts support their firms’ strategic business decisions, particularly when it comes to market trends, competitive environments, and long-term profitability. To develop projections, identify strengths, weaknesses, and other patterns, they examine both historical and current data.

## Cost estimators

Cost estimators are the best resource for getting the most value for your money. To provide precise estimates of the sum of money, time, and labor needed for a particular project, cost estimators frequently collaborate with project managers and engineers. Excel is used to input all necessary information and perform automatic computations for benchmark amounts.

## Educators, teaching assistants, and teachers

In addition to their subject-specific expertise, educators must be adept in planning their classes, monitoring student attendance, and creating lesson plans. The majority of teachers can complete these activities using Excel’s features and support system, making them proficient users of general spreadsheets. Excel is a very important tool for many teachers in their assignments as well as graduate and postgraduate research, in addition to helping them keep track of their students’ contact information.

## Financial analysts, investment bankers, and loan officers

Excel is a favored app among financial analysts, bankers, and other money-focused professionals because of its grasp of money.

Financial analysts assist people and businesses in making wise loan or investment decisions. Although they employ a plethora of financial software, spreadsheets are among the most effective tools for analyzing various financial data sets. Excel has therefore become a requirement for this position.

## Market research analysts and digital marketers

Data science is at the centre of hard core marketing. Professional market researchers rely on their abilities at acquiring, processing, and analyzing field data, drawing on both creative and analytical thinking. These employees rely on Excel spreadsheets to compile and analyze their research. To reach and convert audiences, marketers look for new market opportunities and employ a variety of tactics, including search engine optimization (SEO). To persuade executives of the effectiveness and return on investment of suggested initiatives, they also employ charts, graphs, and other data visualizations.

## Project managers, project coordinators, and construction managers

Project managers can be found in a variety of industries, with the construction and IT sectors dominating. They organize, coordinate, and oversee the creation of software or the construction of various structures. They establish standards, allocate responsibilities to workers, control expenses, and zealously maintain timeliness and budget compliance. Microsoft Excel is one of the main tools they regularly utilize, even if they frequently employ specialist software, to handle a variety of jobs quickly.

## Sales, marketing, training and administrative managers

Given that both sales and marketing are referred to as “numbers games,” it is evident that they incorporate numbers. Spreadsheet software follows numbers wherever they go. While planning, scheduling, and organizing various tasks and resources, frequently with associated budgets and timestamps, are necessary for administration and training. Excel naturally helps make sense of everything when time and money are important. Managers rely on Excel to carry out their primary duties, which range from market research and inventory management to financial modeling and data analysis.

The list is not exhaustive but a good illustration of why everyone needs to learn Excel.
