## Importance of Data Analysis in Modern Society

Data analysis might sound complex, but we do it daily. When you decide what to wear based on the weather forecast or choose the quickest route to school using a map, you learn data analytics! Exploratory data analysis has become even more critical in our modern society and is used in various ways. Let’s take a look at why it is so crucial.

### 💹Making Informed Decisions

Imagine you’re part of your school’s student council and have to decide which movie to show at the annual film night. You could guess which film most students would like, or you could analyze data from a survey asking students about their favorite movies. By analyzing the data, you can make a decision that will make the most students happy.

### 💹Predicting Future Trends

Have you ever wondered how weather channels predict whether it will rain or shine tomorrow? They use data and statistical analysis! Meteorologists can predict future weather conditions by looking at patterns and trends in weather data. Similarly, businesses use business analysis to predict future trends, like what products will be popular next season.

### 💹Improving Services and Products

Companies like the ones that make your favorite video games or snacks use data analysis to understand what their customers like and don’t like. It helps them improve their products and services. For example, if a game company analyzes data and finds that players find a specific level too hard, they might adjust it to make it more enjoyable.

### 💹Solving Problems

Data analysis is a powerful tool for solving problems. For instance, if a city has a problem with traffic congestion, data analysis can help identify the busiest routes and times of day. With this information, the city can develop solutions, such as adding more buses during peak hours or creating new roads.

Imagine understanding complex concepts like linear regression and probability and using them to make sense of the world around you. That’s what this course on Udemy aims to do.

This course takes you on an exciting journey through the world of numbers. It begins with the basics of analyzing data, where you’ll learn about mean, median, and mode. It is like learning how to add and subtract in primary school. These are the building blocks of basic statistics. You’ll also learn about range and Interquartile Range (IQR), a fancy saying, “Let’s look at where most of the data is.” Plus, you’ll get to draw box-and-whisker plots like little pictures that tell you a lot about your data.

Next, the course dives into data distributions. Here, you’ll learn about the variance and standard deviation, which are ways of figuring out how spread out your data is. You’ll also learn about typical distributions and z-scores, which can help you understand how unusual or typical a piece of data is.

Moreover, the course wraps up with probability distributions. You’ll learn about unions and intersections, like the “addition” and “multiplication” of probability. You’ll also explore independent and dependent events, which can help you determine how likely two things will happen together. And you’ll learn about Bayes’ theorem, a powerful tool that lets you update your beliefs based on new data.

### Key Highlights

• Creating box-and-whisker plots to visualize data.
• Understanding the basics of business analytics, including IQR and range, as well as mode, median, and mean.
• Exploring data distributions, including standard deviation, variance, and mean.
• Diving into probability, understanding concepts like intersection and union, as well as independent and dependent events.
• Mastering Bayes’ theorem to update beliefs based on new data.
• Grasping the concept of Regression, including chi-square, RMSE, coefficient of determination, correlation coefficient, and scatterplots.

## Workshop in Probability and Statistics

## Complete Math, Statistics & Probability for Machine Learning

Check on Udemy

Imagine commanding a computer to solve complex problems using numbers and codes. Sounds cool, right? That’s exactly what you’ll learn in the “Complete Math, Statistics & Probability for Machine Learning” course on Udemy.

The course starts with probability, teaching you about dependent and independent events. Think of it this way: if you have a bag of different colored marbles, the color of the first marble you pick might affect the color of your next one. That’s dependent events! But if you replace the marble each time you pick one, then the events are independent because picking one marble doesn’t affect the next pick.

Next, you’ll dive into Bayes’ theorem, a special rule in probability that helps us update our predictions based on new information. It’s like when you change your guess in a game of hide-and-seek after getting a hint.

The course then introduces you to probability theory for machine and deep learning. It is like teaching a robot how to make good guesses and predictions! Also, you’ll learn about linear algebra and calculus for machine and deep learning. These might sound like big words, but they’re just fancy ways of saying, “Let’s use math to make computers smart.”

### Key Highlights

• Understanding dependent and independent events of probability.
• Applying Bayes’ theorem to update predictions based on new data.
• Grasping probability theory for machine and deep learning.
• Using Python to solve complex math problems.
• Linking probability with mathematical statistics to understand their relationship.
• Learning about linear algebra and calculus for machine and deep learning.
