The Path to Becoming a Data Analyst: Skills and Responsibilities

Hey folks, thanks for much supporting my previous article if you have not visit yet then you should read once after this article. I'm Richa! today, let's take a look at the exciting path to becoming a data analyst.

How Data Helps Us Know the Weather

Do you like sunny days? Do you like to hear the birds sing and feel the cool wind? Sometimes you look at your phone and it says it will rain later. How does your phone know that?

Your phone knows that because of data. Data is information. Data can help us solve problems. One problem is to know what the weather will be like. Let’s see how data helps us with that.

Data is like a detective. A detective tries to find out what happened or what will happen. Data does the same thing. Data tries to find out what the weather was like before and what it will be like later.

But where does data come from? Data comes from many places. Some places are far away, like space. Some places are close by, like the ground. Some places are wet, like the sea. All these places have things that measure the weather. They measure how hot or cold it is, how much air there is, and how wet it is. They send this information to computers.

But this information is too much. It is hard to understand. That’s why we need data analysts. Data analysts are people who are good at data. They use special tools to help them. These tools are called artificial intelligence and machine learning. They are not magic. They are smart. They can look at all the information and find what is important.

But how does this help us know if it will rain? Let’s see an example.

Think of making a cake. You have a recipe, but you change it a little bit. You change it depending on how the cake looks and feels. Weather prediction models are like that. They are recipes for the weather. They change depending on the information they get.

Some information is old. It tells us what the weather was like before. This helps the models see patterns. For example, if it was hot and wet before and then it rained, it might rain again if it is hot and wet now. Some information is new. It tells us what the weather is like now. It updates the models. For example, it tells us if the temperature or the wind changes.

Here’s a real story. Imagine a town near the sea. The town wants to be ready for a big storm. Data analysts collect information about the wind, the air, and the temperature. They use their tools to make models. The models can tell them where the storm will go and how strong it will be.

With this information, the town can do something. They might tell people to leave, protect their houses, or get ready for the storm. People are safe, houses are not broken, and people are not scared because they know what will happen.

So, when your phone says it will rain, it is not guessing. It is using data. Data helps us know the weather. Data helps us plan our day and stay safe.

Now, even in education, schools are using Data Analytics to make smart choices. Students can use it to understand how they're doing in school and plan for their future. Here are 5 ways students can make the most of Data Analytics for a better education and career:

1. Personalized Learning:

Now, educational tools can look at how you're doing in your studies, follow your progress, and find where you can do better. This means your learning materials can be adjusted to fit exactly what you need, making your learning experience better and helping you do well in your studies.

2. Finding Strengths and Weaknesses:

Data Analytics helps you see where you're doing well and where you can improve. Knowing your strengths lets you focus on getting even better, while recognizing your weaknesses allows you to work on specific skills that need improvement.

3. Smart Choices in Your Education:

Data Analytics lets schools share lots of information about different courses, how many students are taking them, and how many finish. With this info, you can make smart choices about what to study. Schools can also suggest courses based on what might be good for your future career.

4. Career Insights and Internships:

Data Analytics tells you about jobs in the future, how much money you might make, and important facts about different industries. Armed with this info, you can make better choices about your career. It also shows what skills you need to succeed, helping you adjust your learning to match what industries want.

5. Improving Learning with Targeted Help:

Data Analytics helps schools see if things like textbooks and teachers are helping you learn. They can figure out what needs fixing and make your learning experience better. This means different ways of learning, like using pictures or audio, can be used to help you understand better.

Data Analytics makes your education better by showing how you learn, how well you're doing in school, what jobs are out there, and what skills you need. It makes learning work for everyone, no matter where they are, and helps schools give you the best help possible. With Data Analytics, you get the right tools and skills for a successful future.

Data Analytics Applications
1. Security:
Data analytics, specifically predictive analysis, helps reduce crime rates in some big cities like Los Angeles and Chicago. Imagine using historical and geographical data to pinpoint areas where crimes might increase. While police can't make arrests based on predictions, they can increase police patrols in those areas. For instance, in Chicago, data analytics pinpointed certain neighborhoods where crime was likely to surge. This led to an increase in police presence in those areas, resulting in a drop in crime rates.

2. Transportation:
Data analytics can completely change how we handle transportation, especially when moving large groups of people to specific locations. Think about the London Olympics a few years ago. By using data analytics, organizers could analyze patterns of people movement, identify potential bottlenecks, and optimize transportation routes. This ensured that athletes, spectators, and staff could move seamlessly between venues. For example, data analytics helped predict peak times for transportation, allowing authorities to adjust schedules and resources accordingly. This not only made transportation more efficient but also enhanced the overall experience for everyone involved.

Note: - 
Many freshers are confused about data structures in this field. My suggestion is that there is no need for data structures in data analysis. However, nowadays, a few companies include questions about data structures in their online tests and also data structure can give a analytical thinking to handle approach of problem. If you are relying on your academic knowledge, you can handle these questions easily. So, there's no need to delve deeply into data structures.
