Many people ask this common question “Can I get a job with just SQL and Excel?” or “Can I get a job with just Power BI and Python?”.

The answer to all of those questions is yes.

There are jobs that use only SQL, Tableau, Power BI, Excel, Python, or R or some combination of those.

However, the combination of tools you learn impacts the total number of jobs you are qualified for.

For example, let’s say with just SQL and Excel you are qualified for 10 jobs, but if you add Tableau to that, you are qualified for 50 jobs.

If you have a success rate of landing a job you’re qualified for of 4%, having 5 times as many jobs to go for greatly improves your odds of landing a job.

Does this mean you should go out there and learn every single skill any data analyst job requires?

NO!

It’s about finding the core tools that many jobs want.

And, in my opinion, those tools are SQL, Excel, and a visualization tool.

With these three tools, you are qualified for the majority of entry level data jobs and many higher level jobs.

So, you can land a job with whatever tools you’re comfortable with.

But if you have the three tools above in your toolbelt, you will have many more jobs to apply for and greatly improve your chances of snagging one.

Starting exploratory data analysis (EDA) can be tricky. Many of us often feel lost at the beginning. Here's a simple way to get on track: start by creating hypothesis questions and defining KPIs based on your dataset and the field you are working in.

Will AI Tools for Data Analysis Replace Data Analysts?

AI and Data Analysis are two closely related scientific areas, that have been developing rapidly for the last several years. As technology continues to evolve, the question arises: Will AI tools for data analysis replace data analysts?

This article aims to describe how AI is related to Data Analysis, what it can do, and will AI tools for data analysis replace data analysts. Starting with the introduction to AI and its fundamental aspects, to how it is going to affect the world in the distant future, the article addresses that and also focuses on how AI is associated with Data analysis.

The moderate generation of AI comprises Machine Learning, Deep Learning, and Generative AI. While generative AI is the capability to produce materials and contents like images, sound, and music, Machine Learning is a specific type of GI that prepares an algorithm to feed information to make a prediction.

Let’s go back to the basics...!

Here’s what you do to become a Data Analyst

10 Data Cleaning Techniques Every Data Analyst Should Master:

1. Handling Missing Data

Use methods like imputation (mean, median, mode) or deletion to handle missing values.

In Python, pandas functions like fillna() or dropna() are useful.
 
Example: df.fillna(df.mean()) replaces missing values with the column mean.
 
2. Removing Duplicates

Identify and remove duplicate records to ensure the dataset is accurate. Use drop_duplicates() in pandas.
